Where does the power go in a Dodge Ram?
Where does the power go in a Dodge Ram?
Power flows to the relay control coil from fuse 11 (10A) in the junction block in the left kick panel. Remove the compressor clutch relay, start the engine, and turn the A/C to MAX. Check for battery voltage on terminals 86 and 30 in the relay socket.
What to do when Clutch stops cycling on Dodge Ram?
When the clutch stops cycling, the first thing I’d want to know is if it’s getting power from the compressor clutch relay. You can check that by removing the electrical connector from the clutch, starting the engine, turning the A/C to MAX, and testing for battery voltage on the dark blue/black wire.
How does a / C work on a Dodge Ram?
Here’s how those sensors work. The PCM supplies power to the A/C switch in the heater control head on the light green/white wire. When you turn the A/C switch to ON or MAX, the switch completes the path to ground on the black/orange wire terminating in the center of the dash. The PCM sees the voltage drop and that’s its signal that you want A/C.
Where is the relay control coil on a Dodge Ram?
Power flows to the relay control coil from fuse 11 (10A) in the junction block in the left kick panel. Remove the compressor clutch relay, start the engine, and turn the A/C to MAX. Check for battery voltage on terminals 86 and 30 in the relay socket. If you’re getting voltage, check for PCM ground on terminal 85 in the same socket.
When did Cummins come out with the 5.9L diesel?
By the late ‘90s the era of electronically controlled diesels was upon us. As the deadline to meet stricter emission regulations neared, Cummins developed the 5.9L ISB to power all Dodge Ram 2500 and 3500 trucks beginning by January 1, 1998.
Where does the engine run off the Cummins controller?
The engine runs off the Cummins controller (ecm) on the side of the block. It can only communicate with the pcm. The P1693 sets in the pcm when there is a code in the ecm.
Why does my Cummins engine cut out while driving?
The engine runs off the Cummins controller (ecm) on the side of the block. It can only communicate with the pcm. The P1693 sets in the pcm when there is a code in the ecm. We’ve got a code definitely hiding in the ecm that points to your problem.
What kind of cylinder head does a Cummins have?
Four-valve cylinder heads have always been a great way to squeeze more performance out of a given engine’s displacement and the ’98.5-’02 Cummins is no different.
