Hi all,

Last week I was out for a drive, and while airing back up my little 28l/m ARB compressor shorted out.

The 30A fuse blown and the leads were hot hot hot!

Today I checked alternator output at 2000rpm and was all good at 14.2V so no issues there. I chucked another 30A fuse in the compressor and instant blowout when hooked up to the battery.

Hmm, pulled the lead plug apart and lo-and-behold it's melted to the shizenhousen.

So cut the M/F plugs off and hard wired the leads back together.

Goes like a ripper again, no problems noted in my very quick run without load this afternoon.

So my question is, what could have caused the plugs to melt like this? Could it just be that every time I air up the little compressor is pumping for a good 20 minutes without stopping? It works hard the little thing and it's probably got 25-30 hours run time on it.

Was worried about the input voltage but all seems OK in this regard.

Could there be anything more sinister going on here?
