I have used a key switch for a lawnmower on other tractors. here I needed to use the mag single terminal kill switch.

Very interesting subject. My Fluke meter is really giving me problems and too expensive to replace or repair. What DVM meter would be a good replacement for a (true) TRMS Resistance: 500 MΩ? Manual settings would be fine for cost savings.

Tractor's light switch.

then you would need to turn on the lights to get the exciter active, and risk leaving them on.

the best answer by far is a one wire alternator.

CRS. Can't help with a memory problem.

Me cheap. I have a WD Allis that I use a separate toggle switch to excite the alternator. Start engine, flip toggle switch up/on, then immediately off. Once the alternator is excited, it will charge until the engine stops.

Plan to leave the 3 wire alternator on the Allis until it dies, probably in another 20 or 30 years. On another Allis, several years ago the 3 wire alternator quite. Replaced that it with a single wire alternator.

a delco 10SI alternator is the way to go. This has a built in regulator. if you have to have use a mechanical switch to excite the alternator then the alternator will charge full blast all the time. This will eventually burn the battery up and or alternator or both.

considering also that the tractor is a customers who probably does not have a lot of experience or knowledge in this area. KISS and fool proof. even if it was my tractor, I would not want to have to remember to flip the extra switch every time I turn it off. odds are i'll forget...probably the first time I use it.

Art, you are correct, keep it simple :D

Absolutely not true. The Delco 10SI has been used in vehicles for years. The vehicle manufacturer utilizes an electrical mechanical switch at some point in the start or ignition circuit to excite the alternator.

Agree with Art. Since it's not your tractor, KISS, single wire alternator.

Oh for you cheapsters who what to use the $25 3 wire set up , use a horn button :D , That is what I did before the one wire Delco

Let me correct myself.. I use a 10SI delco I buy rebuilt from the auto parts store that has a built in regulator and a 1 wire hook up.39 bucks with core. The old delcos either had a electronic or mechanical regulator. If you use a old delco with a 3 wire system and twist the two wires on the plug together it will charge full blast all the time.
