Hey gang - I have a 1965 Imperial and I've run into one of those little electrical issues that just come out of now where. The fun kind. So the back story first.
I have auto pilot equipped and it does sort of work, never had it to cause a fuse to blow. Now recently I had my A/C worked on - it's an old school RV2 compressor and all original to the car. It was supposedly rebuilt according to the prior owner but who knows. I took it to my garage to get everything working for the summer heat. They got it running and for a short time it was working. SO I turned my attention back to servicing the AP ( auto pilot ). It was not quite holding speed like it should, but the "speed minder" function was working well. Well one day the A/C stopped working and found out that the compressor was broke and would need to be rebuilt, maybe for the first time. SO I paused my work on the AP and went back to the A/C. After a few weeks, the compressor came back and I had everything re installed and ...working again ...so far it's beed fine.
This bring us up to current time. Now since I've got the A/C working now for the 2nd time, an new issue has arose. I have discovered that the AP is blowing a fuse. The first time the A/C was worked on and working for a short time, I was able to also operate the AP with anything blowing. Now I can't even run the power to the AP w/out it blowing the fuse as soon as I turn the key. And BTW when it blows the fuse, it also disables the A/C from running. Apparently the AP and the A/C share the same fuse; which is a 20amp, and is marked on the fuse block as the ACC --- RR. A/C fuse. What does the RR. stand for? Is the A/C on the correct fuse here? Accourding to the wirirng diagram the AP should be there, but I'm not sure about the A/C or RR. A/C whatever that means. And why is it blowing fuses now, when before both accessorins were operating fine w/out blowing a fuse? No one has messed w/ any wiring, so I'm at a loss ...please chime in with any ideas on this.
