3. Strip back 2” of insulation from each end of cable.

a. Start by making a circumferential cut into only the insulation. b. Next, score the end piece of insulation linearly along the entire length. c. Peel back the insulation to reveal the shielding.

4. Peel back the shielding to reveal a white and red wires as well as a bare wire and two more wires in another layer of shielding.

5. Peel back the second layer of shielding to expose two more wires; green and black .

6. Cut away excess shielding up to the insulation.

7. Repeat process for both ends of the splice to get to the point pictured above.

8. To keep the splice small, offset the wires by trimming each ¼” more than the last as pictured.

9. Trim the wires of the other side of the splice in opposite order of the last so that the wires match up as shown above.

Checking The Load Cell Follow these steps:

1. Check the Wheatstone bridge a. Set your multimeter to ohms (Ω). If your meter does not auto scale, set it to the

just high enough to read 350 Ω. This will likely be the 2k or 2000 setting. b. Referring to the picture above, place one of the probes on terminal 1 (red wire). c. Place the second probe on terminal 2, 4, and 5 recording the resistance at each

terminal. The resistances should match the table below.

2. Check Static Output a. Set your multimeter to the millivolt (mV) setting. b. Check and record the voltage between terminals 1 and 5. A good load cell will

read very close to 00.0mV at rest with no vehicle loaded.

3. Check Dynamic Output a. Set your multimeter to millivolt (mV) as with the last test. b. Place the multimeter pins on terminals 1 and 5 again. c. Have another person rock the drum back and forth a couple inches (careful not to

pinch fingers) each way while you watch the multimeter display. d. Record the high and low numbers seen while rocking the drum. e. Depending on the force applied in rocking, the readout should be ~±.3mV.

3.c.2 - Calibration

1. With no bike on and load cell at top dead center, take note of the dyno torque in settings.

(Dyno torque will only show up without speed if you manually select it in settings and watch in the settings screen. Dyno torque should display where the yellow box is in picture 2)

a. If your dyno torque is within +-5 of 0 with no bike on and load cell TDC, then your

low number is good and does not need adjusting and you may skip to step 2.

b. If your dyno torque falls outside of this range, then the zero torque value should

be adjusted for maximum accuracy.

c. In settings select one of your AUX channels and change the settings to match the

settings in the orange box in picture 1 below.

d. With these settings entered, a non-zero value should show up in the green box in

picture 1 below. Note this voltage.

e. Navigate to the 'AVS 1.1' folder by right clicking the 'AXIS 1.1' desktop icon and

selecting "Open File Location."

f. From within the 'AVS 1.1' folder open the folder named 'AXIS-SETTINGS.' g. Open the file named ‘baseconfig.txt.’ h. Replace the number next to the label “vLi” with the number from step (d). The

number in question is shown in the blue box in picture 3 below. (Note, be sure not to change anything but the number itself. Any change to the syntax such as deleting a comma or parenthesis will make the software crash or not boot up correctly. Attached is a picture of the number that needs to be replaced.)

i. Repeat step 1 to ensure that your dyno torque now rests within a few ft-lb’s of 0.

If it does, move on to step 2.

2. To adjust your resulting HP and torque values, navigate back to the baseconfig.txt file as

described in steps (e) through (g) above.

3. Adjust the value shown in the purple box below in picture 3. Increasing this number will

increase your overall HP and torque values, and lowering it will decrease your numbers.

4. After making an adjustment, do a couple runs with a known vehicle and evaluate the

results. You’ll likely have to make a few adjustments to get the numbers correctly dialed in.

Dyno Manager Calibration Input Follow these steps to set your Dyno Manager calibration figures:

1. In the drop down menu, select which dyno you are using. “Default-MC” for motorcycle,

“Default-UTV” for UTV, and “Default-TRI” for trike.

2. Enter your low input, “vLi,” in the blue box.

3. Enter your high input, “vHi,” in the orange box.

4. Enter your high value, “vHv,” in the green box.

5. Click “Calculate.” The value in the “Gain” box will change.

6. Calibration numbers are now set.

General Troubleshooting Guide

Step 1: LED Check

A. Remove the top panel/cover of the dyno to the left of the drum when viewed from

behind.

B. With the cover off, power on the dyno. C. Locate the red chassis board (the red board mounted to the chassis, NOT the drum). D. On the red board there are 3 LED’s

a. Green LED: This LED should always be on while there is power coming to the

chassis board.

b. Blue LED: This LED will flash while the drum is rotating at a frequency

determined by the speed of the drum

c. Red LED: This LED blinks (~50Hz) to indicate communication with the drum

board. If this light is solid or not on it means the chassis board is not communicating with the drum board and torque is not being read from the load cell. If this is the case, skip to Step 4.

Step 2: Load Cell Wires

A. Open up the software and navigate to the “technical” tab which displays the raw labjack

inputs.

B. Locate the red drum board on the side of the drum. C. While watching the input voltage of AIN06 wiggle each of the wires going into the green

terminal block on the drum board. (See picture) If the voltage jumps at all while agitating any of the wires, try to narrow down which wire it is and examine for loose connections or broken wires.

Step 3: Load Cell Check

A. Check the Wheatstone Bridge

a. Set your multimeter to ohms (Ω). If your meter does not auto scale, set it to the

just

high enough to read 350 Ω. This will likely be the 2k or 2000 setting. b. Referring to the picture above, place one of the probes on terminal 1 (red wire). c. Place the second probe on terminal 2, 4, and 5 recording the resistance at each

terminal. The resistances should match the table below.

Terminals

Resistance

1 > 2

~ 280 Ω

1 > 4

~ 280 Ω

1 > 5

~ 350 Ω

Step 3: Load Cell Check - cont.

B. Check Excitation Voltage

a. Set your multimeter to measure up to 5V. This is commonly the 20V setting. b. Place the black probe on terminal 3 (bare wire). c. Place the red probe on terminal 2 (black wire). The meter should read between

-5.1V and -4.9V.

d. Place the red probe on terminal 4. The meter should read between 4.95V and

5V.

C. Check Static Output

a. Set your multimeter to the millivolt (mV) setting. b. Check and record the voltage between terminals 1 and 5. A good load cell will

read

very close to 00.0mV at rest with no vehicle loaded.

D. Check Dynamic Output

a. Set your multimeter to millivolt (mV) as with the last test. b. Place the multimeter pins on terminals 1 and 5 again. c. Have another person rock the drum back and forth a couple inches (careful not to

Step 4: Grey Cable Check

A. Locate the Grey Cable connecting the red drum board to the black drum coil board. (see

picture below)

B. While watching the input voltage on AIN06, wiggle the wires at each end of the

connector. In addition to watching the voltage on AIN06, also look to see if wiggling the wires have any effect on the red LED.

C. Unplug the grey cable from each connector and using a multimeter check for continuity

through each wire. To do this set your multimeter to ohms and place one probe on either end of the wire in question. A good wire will read within a few ohms of 0.

D. With the grey cable still unplugged check to see that each end is pinned the same.

When viewed from behind with the tab up and order should be red-white-black.

E. Plug the grey cable back into each board.

F. If the grey cable checks out proceed to step 5.

Step 5: Air Gap Check

A. Loosen the set screw on the plastic collar holding the drum coil board on. (See picture

below)

B. Move the collar and drum board towards the other black board so the two black boards

are in contact.

C. Check to see If the red LED is blinking now. If it is, back the collar far enough so the

black boards are no longer touching but the red LED is still blinking and tighten the set screw.

D. If the red LED still is not blinking, place collar back in original location and tighten set

screw.

RPM Troubleshooting Guide

1. First check to make sure that RPM is the only reading not present. If other readings are

also not present then a bigger issue is likely present causing the loss of RPM. If only RPM is not present, continue on to step 2.

2. Check that the ground cable is connected between the electronics box and the vehicle.

In order to read RPM, the box needs a common ground with the vehicle. Once connected check again for RPM. box as well as the USB which provides the 5V power. Wait 30 seconds then reconnect the USB and DC power, order is not important. Check again for RPM.

3. If the injector harness used has two connectors to mate with the RPM harness, try

4. Power cycle the entire system by unplugging both the DC power to the electronics

swapping them. One of the connectors will have the injector signal while the other will have a steady ~12V. Applying the 12V to the RPM input will not damage anything; however you will not have an RPM reading with this configuration. After swapping check again for RPM.

5. Check for continuity in the injector harness as well as the RPM harness with a

multimeter.

a. If no continuity is present, narrow it down to which harness has the open circuit

and contact Dobeck Performance for a replacement.

b. If both harnesses have continuity, move on to the next step.

6. Disassemble electronics box to expose the internals. Depending on the generation of

box in question the procedure to accomplish this will vary.

7. Make sure that the white/yellow wire is going into the terminal labeled FIO4 on the

labjack.

a. If the wire is going into wrong terminal, swap wires to match the picture below.

Check for RPM.

8. Measure the resistance between FIO4 and VS on the labjack. There should be ~1k

between the two.

a. If resistance reading varies beyond 10 ohms, contact Dobeck Performance.

9. With vehicle hooked up and running, probe the yellow wire inside the electronics box.

Work the throttle to increase RPM’s and look for a corresponding decrease in voltage on the yellow line.

a. Repeat previous step on while probing the white/yellow wire. If decrease in

voltage with rising RPM is seen only on the yellow wire, then the RPM smoothing

box is bad; contact Dobeck Performance for replacement.

4.a.3 - Drum Board Voltage Rail Check & Air Gap Adjustment

1. Remove dyno panel to expose the drum board, which is mounted on the side of the

drum. On most models this is on the back left side of the dyno (while looking from behind).

2. Set multimeter to the highest precision DC voltage readout while still being able to read

5V (generally a 20V setting).

3. Place black/common probe on the center terminal (labeled A in the picture above) of the

green 5 position terminal block located on the drum board.

4. Place red probe on the terminal adjacent to the common terminal, labeled B in the

picture above. Reading should be between -4.95V to -5V.

5. Place red probe on the other terminal adjacent to the common terminal, labeled C in the

picture above. Reading should be between 4.95V and 5V.

6. If either of these readings falls out of the acceptable range check the distance of the air

gap between the transformer boards.

a. Loosen the set screw on the collar holding the circular transformer board. b. Adjust the air gap spacing while checking the two readings to bring them into

range.

c. Make sure the transformer boards are not so close that they may rub with

vibration or flexing.

d. If adjusting the air gap space has no effect on the voltage readings and they are

still out of range, contact technical support at Dobeck Performance.
