Testing The Gun
Motor Check
Disconnect 4-pin CPC.
Check the resistance across pins “3” and “4”. The resistance across the
motor should be between 15-25 ohms.
If an open circuit or short exists, check the motor leads and motor
independently of each other. Replace the defective part.
Testing the Micro Switch
Check for continuity across pins “1” and “2” when the trigger is pulled. The
signal should be open when the trigger is released.
