Now i freely admit im no electrician, or a pro at reading schematics, but its nearly 100 degrees outside and I need this to work properly.
I spent half the day getting intimate with my 90 RAM 50 Electric FSM and attempting to diagnose my issue. My problem is that I am trying to make a VR4 ecu work with wiring for a 90 MM. MM has two leads that power/control the unit while the VR4 has 3. They both also use different circuits to activate. Well in my diagnosing I realized that I only had 1 circuit connected to the ECU and needed to tie in the other one somewhere. Well before tying it in i decided to test it to ground. It sparked, so i touched it again, then....nothing.
Ive managed to short out the circuit. Checked all the fusible links in the diagram that I see and they are good. I also get power to the main AC relay which is good, but I now when I go to ground the pin that used to trigger the AC clutch before, I get nada. Not sure what I killed, so im pissed.
I thought I heard something make a click sound from under my dash when it went, but Im not sure. One step forward, two steps back.[/quote]
Update:
Found the culprit of my AC no longer switching on. There is a small controller box under the passenger dash. I picked up another one, plugged it in, and it works again with my jumper wire. Now i just need to hard wire it in. Probably wont mess with it much more until the weather gets a bit better.
While I was at it I took the old girl out for a ride. Man, with the new 31's it drives and cruses soooo much better! I can actually climb a hill in 5th gear on the highway. Anyways there is a fun mountain road that leads up to a Crystal Mine on the opposite side of town. It can get unpassable during the winter, but I thought why not see how it looks. I made it about half the way up until I hit some heavy snow. I might have been able to push it further, but I was alone, and although the 31's are nice, they are not aggressive enough for this kind of off-roading.
Made it about another 1/2 mile up the road until it turned into deep snow and ice.
Looking back from where I came. Opposite mountain range below me. Note: I had to reverse down about 2 miles before I could chance a turnaround. That sucked.
