Mystery brake failure

Chefmick · Jul 12, 2014

Bought second hand ABS pump.Lasted 2 weeks then kept whirring even when engine was off.Got very hot. Disconnected battery before overheating it.This is the third pump of three and fitted by reputable 4 x 4 garage. We assume there is an underlying problem to cause pumps to die, so would it be a relay? Any useful ideas appreciated.

+1, could also be the fuse box

Yep that as well.

We have tried the relay (replaced) and driven it for one week before brakes failed again.
Aren't fuses either alive and working or just dead? Would they have an intermittent fault?

Fuses are good or bad, fuse boxes on the other hand can be intermittant.
