Over the winter the rear suspension air compressor on my '86 345 stopped working. I typically start the rig and inflate the airbags once or twice a month when in storage. The motor isn't getting power. I show 12v
to the air pressure switch, but get nothing when I jump the switch and go direct to the compressor. I applied external 12v
power to the motor and it fired right up. My multimeter shows nearly 12v
on the line I jumped to the compressor. I made sure it was grounded properly...nothing. I'm a novice where 12v power is involved. Any suggestions would be greatly appreciated? Thanks for your time!
