Converting Super H to 12V generator

I’m considering using my SH as my snow plow. I have working pancake 6V headlights on her. For plowing in the dark, I’m considering LED lights and the only pancakes I’ve seen are 12V. I have a 12 V genny on the shelf and don’t want to go with an alternator. Other than a 12V battery and a 12V positive ground VR Is there anything else i need to change? Thanks
 
Should do it other than a resistor if using present coil. Maybe the fuse depending on what size is there now.
 
From comments I've read on other forums using a 12 volt alternator with internal voltage regulator could
prove to be much more reliable than the currently available voltage regulators. Most appear to be imported
and more trouble than anyone needs. Alternators charge so much better at low rpm than generators too.

12V sealed beams for these old tractors are expensive enough for me, not a big fan of LED's, they do
produce a lot of light for the amperage they use but I've never felt the need for them the 22 years I've
pushed snow with my Super H.
 

A 12 volt generator will fit under the hood just like the original 6 volt generator. MOST 12 volt alternators will NOT fit.
 

I would suggest to not go cheap on the VR. I converted my Super C and used a solid state VR. It was about $110 and looks stock because it fits inside the original VR case. Not cheap, but works perfectly. The LED lights are amazing and made it worth it to me.
 
I did my 300U with a 12 volt generator. The generator has worked find for many years but I go through a voltage regulator every 3-4 years.
 
Thanks for the Replies. I always forget something. The coil prolly explains why my SA doesn’t start after i rewired it and converted it back to 6V. Still got a 12V coil. Duh

Which regulators are you using? The local electrical shop sells a $70 USA made regulator that he says is as good as the originals. Are yours USA or Chinese made?

Do you own a cell phone? You didn't 22 years ago.
Do you use the internet? You didn't 22 years ago.

If you are in favor of "upgrading" from a gen to an alt then why would upgrading the lights to LED be a negative?

I mean all this in a light hearted way, but times change. If I were pushing snow with a work tractor it would have LEDs on all four corners if I could swing it. You can never have too much light.
 
Hmmmmm, the Delco 10SI 37 amp alternator on MY Super H fits with a finger's width of clearance to the
valve cover and the hood. GUESS AGAIN about alternators NOT FITTING! The only difference you can see on
my tractor is the lack of a voltage regulator. The price these guys are stating for just a 12V regulator
are TWICE what a new or rebuilt 12V 37 or 61 amp alternator costs, so you can run ALL the sealed beam
lights you can find. No need for expensive LED lights because your 12 volt generator only makes 15 amps.

I see all these hoods Butchered and it really pizzes me off. Do the install RIGHT or hire someone to do
it! Makes me wonder what else the owner half-azzed on the tractor!
