les,
on the supply side they do not need to be DOT approved fittings. some of my spares are and some are not.
before you start tracing wires etc, you should check to see if you have 12v at the compressor itself.
it is the startup current (locked rotor amps) that is blowing the fuses on these things.
these 12v compressors seem to be pretty finicky if they sit unused for a long time. they have a variety of bearing types based on the year they were made. some just have a shaft riding on a oily cloth packing, some have sleeves and some have actual bearings. the newer ones have bearings. how do i know you ask? i had a bad compressor and i took it apart. i bought a NOS one that was still old but never used. it had different bearings in it.
so before you start tracing wirings, make sure you have 12v at the right places AND make sure the compressor is getting it.
you dont want to replace a good compressor. those little babies are quite pricey. no surprise.
