Solenoid Body Electrical Check
All solenoid body electrical functions can be checked in two stages.
The first check determines if the solenoids have a good circuit through the solenoid body to the proper ground paths.
The second check determines whether the solenoids have any ground paths that are shorted, as well as checking pressure switch function and resistor integrity
Check 1:
Connect one ohmmeter lead to solenoid body pin # 4. Connect the other ohmmeter lead to pins 5, 6, 7, & 8 one at a time. If all readings show 1.5 to 3.0 ohms, the solenoids have good circuits through The solenoid body.
Check 2:
Connect one ohmmeter lead to the aluminum body of the solenoid body. Connect the other ohmmeter lead to solenoid body pins 5, 6, 7, 8 one at a time. There should be no continuity or out of limits (OL) on all four pins.
A. If the voltmeter shows a resistance of less than 300 ohms on any pin, there is a short to ground in a solenoid circuit. Replace the solenoid body.
B. If the voltmeter shows a resistance of between 300 and 325 ohms, there is a closed pressure switch circuit. The solenoid body should be replaced, or disassembled and inspected.
C. If the voltmeter shows no continuity, apply air pressure to the solenoid body ports shown in figure two in the following manner:
Apply 60 psi to make sure that the pressure switches can close under minimal pressure conditions.
Apply 150 psi or more (up to 250 psi) to make sure that the circuits can handle the high pressure sometimes sent to the switches.
The pressures, when applied to each of the switch passages, should cause the ohmmeter to read between 300 and 325 ohms. As pressure is released, the ohmmeter reading must immediately change back to an open circuit. If the voltmeter shows any readings other than those outlined here, either replace the body, or inspect it according to the Solenoid Body Service section of GEARS Magazine, issue September '94, "Having An Impact".
