Subject: C650 & V220 No Charge-Q901 & F900 Open
Model Affected: GSM C380, C381, C381P, C650, C651, V180, V188, V220, V226
Level of Repair: 2
Problem
C650 & V220 customer units are being returned with complaints of “Unable To Charge”
or “No Charge”. Development has traced the root cause to a non-conforming charger
manufactured by Leader Elections Inc. (LEI), China. The LEI charger does not have a
bleeder resistor, making it unregulated and susceptible to spikes in the line voltage,
which can lead to excessive charging current-damaging Q901 and blowing F900.
Solution
Short Term:
A global purge is in process to instruct DC’s to remove and return all LEI chargers. LEI
will be replaced with Phihong or Salom.
Long Term:
Product will be sourced from Phihong & Salom-not from LEI.
Service Action
Customer Returns:
Perform the following service procedure on all C65x & V220 returned with an LEI
charger with Charger related customer complaints.
Note: As a precautionary measure, this procedure must be followed if a charger is not
included with the returned unit.
1) Verify that the charger accompanied with the unit is LEI. LEI chargers have the
supplier model number 35048035-A1/A2/C5 printed on the charger’s label. If the
charger is not LEI, proceed to troubleshoot the unit per normal servicing
procedures. Refer to the photo below to aid in identifying a LEI charger:

2) Disassemble the unit to gain access to Q901 & F900.
3) Visually inspect Q901 for damage. Replace if necessary.
4) If no damage is evident, measure the resistance of the Q901 collector-emitter
junction. Replace if the junction is shorted (approx 1 ohm or less). A known good
unit can be used for comparison purposes.
5) Measure the resistance of F900. Replace if open.
6) Reassemble the unit
7) Connect either a Phihong or Salom charger to the unit and verify proper charger
operation.
8) Scrap the LEI charger and replace with either Phihong or Salom.
Service Inventory:
Purge all LEI chargers from inventory and replace with Phihong or Salom.
