In my car I have 2 cigarette lighter outlets.
Dashboard outlet has a 25A fuse in the engine compartment.
Cargo area outlet has a 30A fuse next to it, probably 6 inches of wire between them.
Using one of those small 12V air compressors, rated for 150PSI not 250PSI, I can plug into the dashboard outlet and run on the 25A fuse until the compressor gets so hot I thing it's going to melt the aluminum housing.
However if I plug into the 30A cargo area outlet it will blow the 30A fuse within 5 seconds. Anything else I plug into the back works fine. The plug on the compressor isn't loose or damaged.
How could a compressor (BTW - looks like 18AWG wire) run on 25A but repeatedly blow 30A? Plus, I did try a 25A in the back too, blew that.
Really missing those 1969 carbureted, no electronics power houses.
