1.Remove power to the
2.Perform the Cover and Spindle Mount removal procedure.
3.Locate and remove the two solenoid leads 552 & 553 from the solenoid valve. See Figure F.4.
4.Make sure the gas supply for the solenoid is hooked up, and then apply 12 VDC to the gas solenoid.
5.If the solenoid activates and allows gas flow, then the solenoid valve is good.
NOTE: There should not be any gas flow until the solenoid is activated.
6.If the solenoid does not activate and allow gas to flow, then the solenoid is faulty. Replace.
7.The normal solenoid resistance is approximately 20 to 21 ohms.
8.Normal voltage (with gun trigger activated) measured at the solenoid is 6.5 VDC (leads 552 & 553).
9.If the voltage is not present at leads 552 & 553 the feed head control board may be faulty.
