12volt compressor

.
Hi Trouper,

The symptoms suggest that it could be either the motor or maybe just the " Automatic Thermal Overload Protector". I would put my money on the latter.
These devices can be unreliable. Especially once operated they can develop poor contact conductivity and require replacement. If you can locate the device it can be 'bridged-out' and the compressor run to determine if the fault is the O/L protector or the motor. A good auto electrician could perhaps do this but at a compressor replacement cost of $220 his charge may not be reasonable.

Why not give Derek Bester of ABR Sidewinder a call on 07 3890 5899 and discuss it?

Have you tried it run off a different vehicle?

A couple of possibilities, best case scario is Brushes worn out. I don't thing it would have a brushless motor??? This is simple and relatively cheap to fix.

Worst case scenario, short circuit in motor windings, better off buying new one!

It is most likely the thermal cut out, I had one fail on my dual ARB compressors. You can get new ones from Wagners for about $8 or on eBay for about $2.
If you need the part No let me know and I will see if I can find It.

Cheers
Peter.

Dobinsons suspension have the Thumper on sale for $90. Just bought one and it goes well.
