I am working on my sisters 99 Caravan. The issue started by the Ignition fuse blowing when the switch would be put in the "RUN" position, no other time. Did this for awhile then ran for about a week then died and started doing it again. Then it would blow the fuse only when off idle and now its back to doing it in the run position. I have done a lot of reading and youtubing but have not seen this issue. All acc work, the engine cranks, the only issue is the fuse blowing in run position. With all the research, reading wiring diagrams, youtubing and tracing wires I have found that it only blows the fuse if the alternators 2 wire plug is connected, no other time. Had the alt tested (off vehicle) and it tested good. Any one have any idea if the the alt could have a short that would blow the fuse and still test good or any other idea?
