I'm about to rewire the TEA20.
The electrics have been butchered and modified over the years. I'd now like to start from scratch. I need to look at everything from the ignition switch onwards.
Which is the best way to go for good reliability, alternator, generator, points, electronic ignition, regulator, battery, starter motor, coil? :roll:
If you were to build your tractor electrics from scratch what would you have?

G'Day Doc

I'd do exactly the same again as I've already done on my TEA20:

1. New wiring loom, available from Bareco around $60.

2. Move earth lead from dash to block.

3. Generator and starter overhaul or at least a check. The Lucas generator was fine for Old Harry, worked for 50 years, given me no problems, no reason to change to an alternator.

4. Pertronix Igniter and Pertronics 40 KV coil - a must!! Around US$100 including freight.

5. Make sure every electrical connection is clean and good.

6. Make sure you have a good battery.

Changing the generator for an alternator is a very expensive way to put off replacing a tired battery!

If I were wiring-up my tractor from scratch, and I had no existing 6V battery/generator already , I would go with an alternator, mainly because I like high power 12V accessories like LOTS of super bright lights, a 12V sprayer pump, and whatever other gadget I might like to hook-up. As far as points vs. electronic ignit., electronic is nice, but more expensive. Points work just fine and are very dependable. Go with a 12V coil, not a 6V coil with a resistor. But having said all that, I did re-wire my tractor from scratch but had a good 6V generator and 6V battery, so I stuck with a 6V system and oversized the wiring, all 12 gauge or 14 gauge with super fat truck battery leads to the starter. It's very dependable, but I can only run two 6V headlights without pushing my amp meter into negative territory with my meager 6V generator output, and the lights are not as bright as I would like. I'm waiting for my generator to burn-up to give me an excuse to convert to 12V.... been waiting for 6 years now and that darn generator is still running fine.

Shucks George don't you know that generator will be fine for another 20 years. If you didn't want it to die it would have been gone 7 years ago. LOL Richard
