So, knowing that I have a good dynamo (belt tensioner!) but the rest of the loom is burnt toast, and the regulator and dashboard were full of something that defied identification but may have been the fossilised remains heaven knows what, I find myself looking at an alternator sitting on the shelf. Don't know what it came off of, don't know if it works. It's a Lucas, no model id on it, 2 large spade terminals connected together + power out, and one small terminal ind. Anyone know how to bench test it? I've spun it up with a nut gun and only got 0.2v from the large terminal so do I need to put 12v in the ind line to excite it?
Wifey suggested the 'ABC book of AC/DC' by IC Sparks, but Amazon haven't got it...

I've already changed the tractor to -ve earth so led lights could be fitted and an accessory socket for a phone charger perhaps and will create a new loom as I go so the odd extra wire or ind light won't be an issue, but I don't want to get into modifying the brackets and mountings if it doesn't work. I've looked at, but not sure about, new 1 wire units - I've read a lot about them draining power as well, anyone tried these?
I'm not bothered about losing the dynamo etc., being able to use it far outweighs the cosmetics.
