I am posting this here because nothing else makes sense
A tip I heard about when working on the electrical and you need power. First, disconnect the battery and hook up a low amperage battery charger. You'll still have power and can tell about a short, but you won't have all the amps.
A much much better way is to wire a light bulb in series with the battery
I keep, besides the usual commercially made test lamps.................
A junk stop/ tail socket with 1157 lamp...............
and one or two old headlamps
So in order of low to more current flow, you have
commercial test lamps with fairly small bulbs
The lamp socket using the two hot leads, which puts the two filaments in series
The socket using the tail filament
The socket using the stop filament
The socket using both wires in parallel, both filaments
A headlight bulb.................
and if it's a single, or a low beam quad, you can wire either
low beam, or
both low and high beam in parallel.
There is no wire that I'm aware of in your car, that two headlight filaments won't protect against burn--out.
