need help with vac 12volt

[steven in Tn]

tired of buying a 6 volt batt. every year or so,
so i am switching over to 12 volt. just finished
making my brackets and hooking every thing up.
am using a 3 wire alt. with built in regulator.

i know i have to run a jumper from #2 on alt.
to the stud on the alt. and also a wire from the stud on alt. to the ampmeeter.
but where does the wire from the #1 go?

thanks for any help

This is a Delco 10si that someone on TT posted a couple years ago. You can use a diode like shown, a resistor, or a lamp like a brake light in the sensor wire to prevent run-on.

I change the ignition switch to a 4 terminal switch, connect the sensor wire to the acc terminal and don't need the diode, etc.

I think you are making a good move despite what some of the guys here respond with larger gauge cable, clean connections, etc. I don't doubt I have hand cranked more times than anyone here and that was back in the day when an alternator was still some engineer wet dream.

i have hand cranked these things several times,
but i use this tractor to push up brush piles
and burn the brush. nothing like backing in a burning brush pile and choke the tractor off,
and hitting the starter and hearing it grunt.

Any ideas why you have to replace batteries every year? I seem to get 5-6 out of a little 6 volt on the farm.

It might be easier to use a battery tender. I have doubled the life of every 6 volt battery that I own. I can easily get 4 years out of one. The battery tenders are pretty inexpensive at about $40. It might save you the hassel of switching to 12 volt. If you do the switch, be sure to save your generator for someone who may want to go back to original.

If you are going to use your 6 volt starter and the tractor gets used a lot, plan on replacing a broken starter drive about once a year, keep a couple on the shelf.

I changed my VA over to 12 volt 25 years ago and have never had one problem with the starter at all, just a guess but around a 1000 hrs in that time,my two cents cnt

I am pretty sure my DC has been 12 volt since about the time my Granddad picked it up from the dealer in 1954, and it has never had a broken starter. I don't have any charging system on it. About once a month pull the battery and put it on the charger. As long as I can get the motor to roll over at all, it fires right off!

I don't see a problem, doesn't the resistance to rotation of the engine determine the torque required of the starter?

the batteries around here are junk like every
thing else. and are hard to get around here
