Converting from generator to alternator
Discussion
I'm looking for a little project to do and thought converting my old tractor from a generator to a dynamo might be fun and not too complicated. At present it has a titchy generator and as I have added a few extra lights it's probably not a bad idea to make the swap.
Does anyone know of a generic basic guide to what's involved electrically? I know I will need to source a second had alternator that will physically fit.

Converting from dynamo to alternator was very common in the classic car world. Just be aware that in those days some were positive earth, not the normal negative earth common today so if yours is positive earth & has anything fitted that requires a positive earth you'll have to change that as well. The first car radio I bought - 1971 - had a switch fitted which enableb it to be used with either but anything since has been neg earth only.
Any amount of 'how to' on the net,try a Google "converting from dynamo to alternator". Here's a random one:

That Link above does not show the correct way of doing the job, it is a very poor method and not one that is used by any true tradesmenAny amount of 'how to' on the net,try a Google "converting from dynamo to alternator". Here's a random one:

The heavy brown and yellow wire that originaly connected to the D Terminal on the Dynamo should be discarded, a suitable gauge wire should be used for the power supply to the Alternator and it is the Alternator Maximum output that defines that gauge of wire
Keep well away from that link unless you wish to burn out your tractor
I started driving in 1971 & the majority of cars my friends & I were able to afford were fitted with dynamos. Changing to alternators was a fairly common mod & I was involved with a few, but the last was a long time ago! Worked & we didn't set any on fire or melt the wiring.
Thank you for the diagram, I'm sure the OP will find it most helpful.
