I've got a reproduction Rally Pac on my '65 convertible. Ever since I bought the unit 5-6 years ago, I've never been able to make the rally pac lights come on at night with the regular instrument cluster lights. Things work great until I plug in the leads for the rally pac lights; the minute the rally pac light leads are plugged into the underdash harness, it immediately blows the instrument light fuse in the fuse panel. It acts exactly like there's a dead short somewhere.
I seem to remember hearing that there was a run of reproduction rally pacs made with the illumination wires crossed. With the hot wire going to ground and the ground wire going to hot, it would yield a short exactly like I'm experiencing.
Has anyone run into this yet? I've taken the Rally Pac out of the car and have it disassembled on the workbench. I expected to find an obvious wiring mistake, but so far, nothing sticks out. Again, the regular instrument lights light up fine until the rally pac is plugged in, leading me to think that there's a problem in the rally pac itself.
Thanks for any help!
