I have an underhood light and a second wire with a female spade underhood. I probed it with my meter to the battery, measured 4V to one terminal on the battery, -8V probed to the other terminal.
This seems to me that we have a voltage divider with two different resistances on either side, one twice or the other.
Question becomes, what is the best way to trace the location of the short that is causing this, when the wires are caught up in harnesses under the dash?
I think it must be some sort of supplemental underhood light or something. There is no functionality I miss, no fuses open. Battery holds strong at 12.7V. It is disconnected underhood. But I’d like to see where and why it is doing this.
Fortunately I’ve never had to diagnose shorts like this before. Whats the best bet to start?
