how to find a short
I pulled three marker lights to replace them with Led's.
I installed 1 LED assuming the wire I tested for zero OHM was the ground.
When I put a spade fuse in the plug it blew. I tested the marker light terminal on the plug and it is grounded somewhere (not inside the plug , I checked).
Can a more precise OHM reading tell me which of the marker light wires is the culprit. (since I have to assume upon removing one of the three lights, I must have pulled on the positive wire and grounded it)
I already tried to push the wires back in as far as I could to see if that might remedy the problem. And the lights worked just fine before I pulled the three marker lights.
