Thread: Winch with or without engine running?

Not worth recoing if the rectifier or stator is gone, too exxy for parts.

New they are pretty $$$, if the Transit one Pat suggests is a goer, give it a whirl. Could you post up some part numbers please? I may go that way in the future if the value is in it for a conversion.

Both regs looked remarkably similar, only the brushes are replaceable on the Marelli but not on the denso. So I hacked out the brushes my Denso and put them in the Marelli regulator to see if that was the problem, put the Marelli regulator in the Denso alternator (all bolt and fittings matched up)and fired the disco up. The volts went immediately from 12.3 to 14.2. Yippeeeee. So now all I will do is buy a new Regulator, think I will go for the Marelli regulator the Denso one has no heatsink, that crappy filling behind the regulator and no possibillty of replacing brushes without destroying it.
I feel like going back to those 2 so called Auto Elecs and telling them what I now think of their expert diagnosis.
Also as advised by all the above previous posts. YOU DEFINATELY CAN AND SHOULD WINCH WITH THE MOTOR RUNNING!!
Thankyou Drivesafe and Justin, I as well as others value your experienced input.

Good stuff Pawl!! There is a definate advantage in 'having a go' sometimes, this sort of thing is what keeps vehicles going enough to get home in remote ares etc. That is also a reason to keep some of your old gear...just not too much or the misses will freak out when it starts being stored in kitchen cupboards
In defence of the auto elecs to a degree, the cost of repairing it to a reliable and warrantable standard is too much usually, I wouldn't repair an alternator like you did and then expect to charge them for it

I am however impressed with your ingenuity
