Let's talk about an electrical overhaul

Apparently there is such a thing as a 12v generator. And a 12v battery is now made that is the same size as an old 6v, so it will fit in the new battery box I am getting. That sounds like a good ticket. The power of 12v, with the stock look of a 6v. But what do you all think?
What about replacement wiring harnesses? Are they necessary? Do they look stock?

Also, I want the look of the original operator's starting system that used a simple button. However, I want to secure my tractor when I'm not there for the safety of my kids. Can a key lock be hidden somewhere? Or is there some other safety device that I can install that will ensure the tractor can't be started until I want it to be started?

YES you can get an exact and same sized genny for 6 or 12 volts NO PROBLEM, either get a new or used or rebuilt (or even have old 6 volter upgraded to a 12) genny and a Voltage Regulator to match what voltage you choose, piece of cake.

You can still use the original 6 volt starter regardless what voltage you choose.

The light bulbs have to be 6 or 12 volt depending on what you choose.

If you go 12 volts you can EITHER use a 6 volt coil but add a series external voltage dropping (12 to 6) ballast resistor or else get a full true 12 votl rated coil, no ballast needed. Of course if you stay at 6 volt use a 6 volt coil. I see no reason to convert an H myself, why go the expense of making her look original when original itself is fine??? so pay your money and make your choices.

If all you're after is to make the tractor LOOK stock, you can tuck that alternator up under the hood and nobody will be the wiser. I've heard that it's tight but it will fit.

Alternatively, you can get a Hitachi 14231 alternator. It sorta looks like an old Delco generator, tucks up under an H hood quite nicely, and again, nobody will be the wiser.

What I found that fit well into a stock H battery box was the Champion Group 25 12V battery. Used to get them at K-mart but they've since switched to DieHard now that they merged with Sears.

Replacement wiring harnesses are readily available – some look just like the original. The one’s I’ve seen from Agri-Services (www.wiringharnesses.com) are excellent but there’s other good ones out there. Or if you want to spend less, buy the appropriate (braided insulation) wire and tape and make your own harness.

As you note 12 volt batteries to fit in the old box are readily available.

As for “key switch” security with the OEM style pushbutton starter, you might install a key operated master cutoff switch (punch below) near to battery or starter. I’ve seen several on tractors at shows – they're unobtrustive and they work great.
