Chapter 2: Overview

The inTELLECT EXP-1000 HD tests 6- and 12-volt heavy-duty automotive and commercial batteries, and 12-volt and 24-volt charging systems. In addition to a standard single-battery test, the EXP has a test routine designed for multiple-battery vehicles and a specialized heavy-duty battery algorithm for larger batteries. Other tools in the EXP include a digital multimeter with a scope, and a conductance cable drop test.

The large backlit graphical screen and icon-based user interface make diagnostics simple for the novice and experienced electrical technician. An alphanumeric keypad with selection scrolling and soft (multifuncti

on) keys make the EXP as easy to use as a remote control or cell phone. A memory card system allows

for upgrades, quick storage, and transfer of test data.

Chapter 4: Test Preparation

Inspecting the Battery

Before starting the test visually inspect the battery for:

Cracked, buckled, or leaking case. If you see any of these defects, replace the battery.

•

Corroded, loose, or damaged cables and connections. Repair or replace them as needed.

•

Corrosion on the battery terminals, and dirt or acid on the case top. Clean the case and

•

terminals using a wire brush and a mixture of water and baking soda.

Low electrolyte level. If the electrolyte level is too low, add distilled water to the level specified

•

by the battery manufacturer, and fully charge the battery. Do not overfill.

Corroded or loose battery tray and hold-down fixture. Tighten or replace as needed.

•

The preferred battery test location is in the vehicle. However, if you plan to test out of the vehicle:

Always disconnect the negative cable from the battery first and reconnect it last.

•

Always use a carry tool or strap to lift and transport the battery.

•

CAUTION: To ensure accurate test results for Group 31 batteries, the clamps are designed to connect to lead stud adapters or to the lead bases of threaded studs. Never connect the clamps directly onto the threaded studs. When testing at side posts, always use lead terminal adapters. Do not use steel bolts. To avoid damage, never use a wrench to tighten the adapters more than 1/4 turn. Failure to properly install lead terminal adapters, or using adapters that are dirty or worn, may cause false test results.

At the start of the test, make sure all vehicle accessory loads are off, the key is not in the ignition, and the doors are closed.

Additional Test Requirements

For a more decisive result the analyzer may ask for additional information or further explore the battery’s condition. The following messages and instructions may appear before the analyzer displays the results of your test.

System Noise Detected

The analyzer has detected computer, ignition noise, or parasitic drain, and will attempt to retest. Make sure all vehicle loads are off, doors are closed, and the ignition is in the off position. The analyzer will automatically retest when it no longer detects system noise. If the message reappears:

You may be testing too close to a noise source, such as a charger or other high-current

•

device. If so, move away and retest. If you are unable to find the source of the noise, fully charge the battery and retest. If the

•

message appears after recharging, test the battery out of the vehicle. Disconnect the battery cables and retest.

•

Unstable Battery Detected

A battery that is weak, or that has just been charged, may retain enough electrical activity to be detected by the analyzer and will adversely affect the test results. A fully charged battery should stabilize quickly, after which the analyzer will automatically retest. Weak batteries should be charged and retested. If the battery is fully charged, check the clamp connections.

Deep Scan Test

In some cases the analyzer may need to further analyze a deeply discharged battery to determine

whether the battery should be replaced or if it has a chance to be recovered. It then briey conducts

a Deep Scan Test of the battery. The EXP may also ask you to enter the battery’s six-digit serial number, which is located on the

Check to ensure there are no loose connections and that the ground connection is normal. If there are no connection problems, replace the regulator. (Most alternators have a built-in regulator requiring you to replace the alternator. In older vehicles that use external voltage regulators, you may need to replace only the voltage regulator.)

The regulator controls voltage output based on the battery voltage, underhoo

d temperature, and vehicle loads used. In other words, it controls the maximum voltage the system can produce based on the current needs and amount of current that can be produced by the spinning of the rotor in the alternator. The normal high limit of a typical automotive regulator is 14.5 volts +/–0.5. Refer to the manufacturer specifications for the correct limit, which may vary by vehicle type.

A high charging rate will overcharge the battery and may decrease its life and cause it to fail. If the battery test decision is REPLACE and the charging system test shows a HIGH OUTPUT, check the battery’s electrolyte levels. A symptom

Chapter 9: Cable Drop Test

If the test results for the starter or charging systems indicate that there may be a problem, you may want to perform the Cable Drop Test to determine if it is due to worn cables or bad connections between the battery and the alternator or starter. Worn cables or bad connections create higher resistance, which causes a drop across the circuit. The voltage drop reduces current carrying capability that displays the same symptoms as a weak alternator or starter and causes premature battery failure.

There is no need to run the engine. The Cable Drop Test uses Midtronics’ conductance technology to send a signal through the circuit to the component under test. The EXP then simultaneously calculates voltage drop on the positive (+) and negative (–) sides of the circuit as well as the total voltage drop. The amperage range for each of the four tests is 0 to 1000 A. When you change the setting from the factory defaults, the EXP will store your setting in memory for your next test.

There are four preset tests for components up to 1000 amps:

The test requires two test lead connections, as shown in the illustration below.

Connect the battery test leads at the component’s output lead (the B+ or output screw on the alternator) and the component’s housing as ground.

2. Connect the DMM test leads at the battery terminals. NOTE: The test requires a complete circuit. If you are testing a system with a remote solenoid, you
