Testing The Gun
Reference the “W” clocked gun wiring diagram on
the Prince XL Lincoln Compatible electrical diagram
for information about pin-outs and locations.
Motor Check
Remove the gun connector from the cabinet.
Using the gun Amphenol connector, check the resistance across pins
“A”
and
“B” (motor leads).
If an open circuit (more than
K ohms) or short exist (less than 2 ohms)
exists, check the motor leads and motor independently.
Testing the Potentiometer - “W” Clocked
Using the gun amphenol connector, check the resistance across pin
“D”
(wiper) and pin
“C”. The resistance should vary from 0 - 5K ohms as the
potentiometer is turned.
Check the resistance across pin
“D” (wiper) and pin “G”. The resistance
should vary from
5K - 0 ohms as the potentiometer is turned.
Testing the Micro Switch
Using the gun amphenol connector, check for continuity across pins
“E” and
