Section 21 Testing the Torch
21.1 Motor Check
Remove the torch connector from the cabinet.
Using the torch Amphenol, check the resistance across pins “A” and “B”
(motor leads). The resistance across the motor should be between 5-10
ohms.
If an open circuit or short exist, check the motor leads and motor indepen-
dently.
21.2 Testing the Potentiometer
Using the torch Amphenol, check the resistance across pin “D” (wiper) and
pin “C”. The resistance should vary from 0 - 5K ohms.
Check the resistance across pin “D” (wiper) and pin “G”. The resistance
should vary from 5K - 0 ohms.
21.3 Testing the Micro Switch
Using the torch Amphenol, check for continuity across pins “E” and “F”
when the trigger is pressed.
