What to do if the air solenoid valve is sticking in my Rosco Utility Vehicle?
If the air solenoid valve is sticking, it might be due to dirt or gummy deposits causing the spool to hang up, damaged or warped valve bodies. The most reliable repair is to replace the valves. You can also check the truck air system for water or contamination.
Why are the solenoids hot in my Rosco Maximizer 3B Utility Vehicle?
If the solenoids are too hot to hold after being energized, it could be due to a short in the solenoid wiring. Check the voltage marked on the side of the solenoid; it should show 12V DC.
How to fix air solenoid valves leaking in Rosco Utility Vehicle?
Leaking air solenoid valves can be caused by a jammed or sticking spool section on the air valve. To fix this, replace the spool. Remember to block at A & B ports with pipe plugs and bench test the assembly with shop air supplied to the inlet. Manually and/or electrically operate each valve section to ensure proper operation.
