2000 BB TC1000 w/2 Carriers. Compressors are hung on the bottom of the engine, run off two separate belts.
Rear comp. is not getting 12v. I can feed 12v to it and runs fine. I guess the pressure sensor is not sensing
the 134a is a bit low but not much.... maybe enough to cause this.
Problem: I can't find the sensor. Thought I'd ask first if anyone knows, otherwise I will tear into the loom and trace the wire. I need a tone thingy but.... All the A/C plumbing is under the bus. I guess it would be on the hard high pressure line somewhere?
