Bench Testing an Alternator.

Closing post for this one...
Finally fitted isolation block kindly donated by Mocki...
Added a regulator and tested using method above. Ran at high speed with a 240v drill and alternator output topped 13.8 volts. That's good enough for a spare alty. So many thanks to all contributors. Still learning.
Who would have thought the isolator block plays such a minor/major part.

Whilst I’m getting on a bit these days , I’m fairly sure it wasn’t me that sent you a isolator block ....
glad to hear it’s working all the same .....
isolation of the positive from the negative is pretty damn crucial tho...

Oh! How embarrassing.

A quick check reveals it was Rob. Sooo. A big thanks to Rob for donating the isolator block and to all for the replies.

I have been called a lot of things in my time, but Mocki is a first.

Easy mistake to make , Robs the short a*** one

Hang on, isn't that what Timmy called you.

[Mocki]

Yeah....

Well that put's to bed the urban myth you will never see Mocki and Rob in the same room!
