just a tip that may help at times

BTW if your ignition, or any other electrical component is blowing fuses step one is getting a shop manual so you can easily trace the wires and colors, obviously if it blowing the fuse the indications point to a short or ground, being the cause,but a component that got wet or a wire that got pinched during an accident or during a repair is most likely, I generally remove the fuse and Ive got a test fuse I soldered two wire leads to that connect to a 9 volt battery powered buzzer, it plugs in where I removed the fuse and buzzes,unlike a light so you don,t need to keep looking at it, I then I go looking for loose or rusted connectors, pinched wires, loose grounds, etc. when you find one the buzzer either tends to get louder or stops

 

you simply take a blown fuse and solder the leads to the buzzer to the legs and insert it into the fuse box just during testing, but its a very good idea to put a inline fuse in the leads so you don,t have problems, obviously you don,t need more problems caused by testing

That is wicked smart Grumpy! I am going to make one of those myself.

I use something similar that uses a automotive circuit breaker instead of fuse. It will save a bunch in fuses and reset itself.

Will this work for any car, because my 72 Suburban's brake lights won't light up.
