Blowing #4 Fuse/ No Tail lights, Cluster, Parking Lights, License Plate light

I just provided general information on how to test a circuit that is blowing fuses. I don't think the tail bulb is a better way but they both work. The tail lamp bulb is the same test and finds the same "hacks" as the meter, but you have to check/see it with each disconnect versus hearing it and requires a "heavier draw" than a meter beeper.

You can also use door buzzers or anything that runs on 12vdc that can handle continuous operation while testing (not a car horn) and provide an audio indication it is working.
