I was installing a set of Meso’s puddle lights and after running the wires from the doors to the a-pillar I disconnected the wiring connector in the a-pillar where the y-harness connects. I then plugged the y-harness in and reconnected the battery. I immediately saw smoke from under the dash and attempted to disconnect the y-harness but had already melted some wires. I never made it as far as connecting the wiring from the doors to the harness.
Confused about why the wires melted at first but eventually realized I had mistakenly swapped a 30 amp fuse with an adjacent 7.5 amp fuse at some point in the past.
Cant explain why installing the y-harness would have caused a short though. I’ve tested the harness and couldn’t find a problem with it. Prior to installing though, everything worked fine.
At this point I’m looking for help to understand what I’m experiencing. It actually seems to be two problems. One with the panel illumination and one with the dome light circuit. Currently the dome circuit is shorted to ground and I can’t seem to find where. I’ve checked it with the roof harness disconnected at the A-pillar and the dome wire appears To be grounded somewhere under the dash. Stranger fact is that the panel illumination circuit also appears to be shorted but only when the doors are closed. In other words, the panel illumination fuse blows immediately when the doors are closed but works fine as long as they’re open. I don’t understand why the panel illumination would be connected to the door switch or the dome circuit.
I‘d Like to try to solve this one problem at a time so if anybody can offer a suggestion on the panel light circuit, I’d sure appreciate it.
