1.Remove input power to the machine.
2.Perform the Case Cover Removal Procedure.
3.Locate the gas solenoid and lead connections. Do not disconnect the leads. See Figure F.2.
WARNING
ELECTRIC SHOCK can kill.
•Have an electrician install and service this equipment. Turn the input power OFF at the fuse box before working on equipment. Do not touch electrically hot parts.
4.Turn the machine on and pull the gun trigger to con- duct the voltage test.
5.There should be approximately 6.5 VDC at the sole- noid.
6.If the 6.5 VDC is missing or is low, check the leads and connections between the solenoid and the con- trol board. See Wiring Diagram.
7.If the leads and connections are good to the board, verify the correct supply voltage 9
8.If voltage is correct at P3, the control board may be faulty. Replace the control board.
9.If the 6.5 VDC is present at the solenoid leads and the solenoid does not activate, the solenoid may be faulty. Normal solenoid coil resistance is approxi- mately 22 ohms.
10.The solenoid can be further checked by discon- necting the solenoid leads and applying 12VDC directly to the terminals. If the solenoid does not activate, the solenoid is faulty.
11.Replace all disconnected leads and replace the previously removed case cover.
