Recently I noticed that the left side of the instrument panel was very dim at night. (87 Towncar) I thought that bulbs needed replacing, but I was wrong.
While replacing the electric window motor on drivers rear door I had motor and cigarette lighter disconnected. Suddenly the dim dash lights were very bright again. I left the cigarette lighter disconnected and dash lights are fine now. I suspect there was a small short or something draining power.
I replaced both batter cables. The negative black cable touches metal on several places so i put one of those plastic flex tubes over it. After doing so the drivers door electric window now moves much faster as if it has more power. Could it be that the new battery cable could of been leaking power on the places it touched metal?
How do I find other small shorts or places where current is being leaked?
