Electrical system decisions

I need help making a decision about my H's electrical system. First let me say for anyone who has been following... I won't be able to make my personal goal of October for having my H up and running. It's just not in our budget because of taxes this year for the new house, but next year should be better, and I'm hoping to use some tax refund for restoration.

Anyway, my electrical system seems to be an eclectic smattering of parts wired together. I'm going to be adding a light bar with lights and a rear light. Also I have to add a light control box with the ammeter in it, and the start button mount opposite of that. I'm going to be switching from a distributer back to an original mag as well.
It has been suggested to me by some local tractor club members that I should convert to 12v, especially for a tractor like mine that won't see a lot of work. Ease of starting, and less wear on the starter were two main reasons. Plus the lights of a 12v system are actually brighter and usable, I am told. And I can make it all look like the original 6v system. So, I've been chewing on that idea.

Let me show you what I have right now.

Here is the battery mount. I'm not sure if these are the correct 0 or 00 cables needed for 6v. How do I tell?

Here is, I'm assuming, a voltage regulator. I can't read that sticker. It's sitting where the starting tank will go, rather than under the main tank mount, where I will move it, or whatever replaces it.

And here is, I'm assuming, the solenoid. There is a up and down switch, I'm assuming acted like a key. I didn't know you could use a solenoid for a 6v system.

So, there is my electrical mess. What should I do with it?

Mike, I am with the guys that say get it going first. If you put the mag on it you can still use the starter to start it. If you end up taking the other electrical stuff off you can still hook the battery to the starter to get it to crank instead of breaking your arm. third party image

My A has a mag and nothing else electrical else on the tractor. I start it by hand crank, but I can hook a battery to the starter and start it that way when it is cold. Ron

Hmmmm.. That is an idea I never considered. third party image

We could start a YT betting pool on how long before I break my arm! :lol:

I would have to get thoroughly schooled on how to properly crank the engine first, but that is certainly a good idea that doesn't force me one way of the other with the battery. Thanks for this!

I am thouroughly confused but as far as a solenoid goes you dont need one if you have the proper starting button. If you are using a key swich you will need on . ----- ---Im still confiued

Be sure to note where the rotor is pointing when you pull the distributor. When you install the mag rotate the rotor to the position the distributor rotor was pointing. Connect the plug wires in the 1-3-4-2 firing order and it should start. You will need to connect a grounding wire
for shutdown. Hal
PS: All you need is gas and you can use the tractor. It was done for years by hand cranking
most tractors.

That was my thought as well, however, my questioning came up when I thought I'm going to spend $70-$80 on a 6v battery. And if I change to 12v I will have to spend another good chunk to replace the perfectly good battery.
It's me trying to be cheap, really.

In my opinion, the starting point would be to get it running the way it is. the prior owner did fair wiring, and at least bundled it. When money and time permit, hunt for and get a wire loom for the tractor (commercial pre-made unit) and hunt for a 12 volt generator and correct regulator. for 12v negative ground. (if you want to be correct police perfect, it needs to be 6v pos ground) The wires look serviceable and are OK and probably located where they belong. The battery shelf is wrong, it needs a battery box with sliding bolts on the bottom and a lid that slides under the fuel tank in that location. The best bet is to get it running. JimN

One of the battery cables has a replacement end on it. Many people are of the opinion that they are a tempory solution at best. Take it to the parts store and ask them for a replacement of the size you need an then decide if it matches the diameter of the one still on the tractor. One photo shows the rubber insulatiion pulled away from the connector. It will corrode at that point and it will create more resistance. I usually let that type of stuff go, but it will be a problem eventually.
