AMC Eagle automotive breakers

 

Original diagram of inexact provenance

While replacing the dome light bulbs with LEDs (that post will be up when I’ve figured out what I broke to make them stay on all the time) I blew the dome light fuse, and I didn’t have another one.

original fuses (and my electronic flasher with polarity swapped)

Rather than buy a fuse I checked and found that for most higher values of automotive fuse there are breakers available.  These breakers take more to blow them than the original fuses, I know this because I blew the dome light one intentionally so I wouldn’t run down the battery and it takes more than a tap with a screwdriver to make them pop.  Despite the danger of having something less sensitive as part of my ‘please don’t go up in a ball of fire’ safety system I decided to go with breakers for convenience.

ditched

Our Eagles use standard (not mini, maxi, or micro) automotive fuses and values of 3, 7.5, 10, 15, 20, and 25 amps.  The 30A one is already a breaker in mine and I don’t have power windows so I can’t report on that one.

Living in the future

I replaced my 3A fuse with a 5A breaker, my reasoning is that usually there is not a low resistance path that causes heat build up that will hurt the vehicle.  Usually there is a dead short that if left alone to pass 50 amps or so will burn up the wiring quickly.  This breaker will still protect against that, but I admit I am opening myself up to potential problems on the lighting circuit.  If I ever find a 3A breaker I’ll install it.
