charging options

mike paulson · Feb 13, 2010

hey guys i was just talking to a auto/tractor electric shop owner about options for putting a charging system back on my 6v IH 300. he said for about 100 bucks he would make me a 6v altenator with a built in reg, and all i had to do was hook up one single wire to the batt. the advantage to this is an alt will put out some 40 amps in comparison to 20 that the original generator would have. also the original Volt reg would no longer be needed....i bought this tractor with no generator and thought this might be a thrifty way to put a charging system back into it...i would of course just have to fab some brackets..

You can also buy them brand new from The Brillman Company for 102.00. 40 amps 6 volt pos or neg ground.

Call John Brillman at 1-888-274-5562 and ask if these alternator like some others he sells have been reworked inside for low rpm exciting.

I use some of the reworked 12 volt single wire alternators he sells with the 2 1/2 inch pulley and they excite very well.
The small pulley get's the rpm's up at the alternator.

I wouldn't do it. The 300 never started very good with 6 volt when it was new. Unless you are an absolute purest. (which you are not if you use an alternator) I'd go with 12 volt.

Jeff Z. · Feb 13, 2010

Other than changing over to 12 volts you could also use a 8 volt battery on the 6 volt system.

If I was doing the job to my tractor I would go with a 12 volt three wire internal regulated alternator with a voltmeter and also a alternator warning light on my dash.
This alternator will also provide voltage sensing for maintaining a steady 14.5 volts to the system.
Really nice set-up.

I use voltmeters when using alternators.
You can also use a ammeter and a voltmeter.
You decide what you want to use.
Good Reading Voltmeter/Ammeter

f i go with a 12v pos ground i iwll of course have to get a hold of a 12v batt but will i have to do anything to beek up existing wiring like on my gauges etc? doesnt have headlights...

No Mike. Actually 6 volt takes heavier wire than 12 so you are fine there. With no light bulbs the only thing you need to do is put a resistor ahead of your 6v coil. The only electrical gauge on a 300 is the ammeter and it dose not care what voltage there is anyway.

Jeff Z. · Feb 13, 2010

You would need a 12 volt coil with internal resistance or use a ballast resistor on the 6 volt coil. The starter will be ok with 12 volts.
If you have a pos ground system now you will need to switch around the wires on the coil.
It will work either way but better if the wires are switched.
+ side from the battery to the coil.
- side of coil to dist for neg ground.

hanks for input Cowman. what type of resistor as far as ohms, would it be like the ones they used on the firewalls of like the old Chryslers.

Jeff Z. · Feb 13, 2010

I don't know that model to well if it's gas or diesel. If diesel you don't have to worry about the coil.

I think it only came gas or propane.

Jeff Z. · Feb 13, 2010

I usually use 2 gauge battery cables for 12 volt.

Jeff Z. · Feb 13, 2010

You can just get a coil like this one at NAPA and you won't need to mess with the resistor.

ea a standard 12v coil with built in resistor, yes the tracor is gasoline. maybe i just will go for the 12v upgrade....thanks Jeff...

Owen Aaland · Feb 13, 2010

If your battery is good and it is starting well for you you might consider installing a six volt negative ground alternator. I would wire it for a three wire hook up, install a diode in the excite wire, reverse the wire on the coil, ammeter, and battery. Then if in the future you would want to convert it to 12 volt all you would need to do is change the battery, regulator, and light bulbs, and add a resistor to the coil.

Alternators are simpler if you stay with negative ground and the only difference between the six volt version and the twelve volt one is the regulator.

Jeff:

That's exactly what I'm doing with my 350 Utility. I got a 12V 3-wire alternator and a really nice universal mounting bracket through eBay from Kansas Select Products for about $95 including shipping. New Sunpro gauges (water temp, volts, and oil pressure) came from Advance Auto.

The hardest thing about the whole installation was finding room in the gauge panel to squeeze in the idiot light.

I appreciate originality, but sometimes functionality trumps it.

Original is ok for some but with the right modifications it makes for a better tractor.
The way I look at it it's a tractor not a $100,000.00 sports car.

ea Jeff, i say we are paying pretty good homage to these 50 yr old machines by using them for exactly what they were originally built and designed for...no corporation in the world that wants to make something that is functional for 50 years today.

i wonder what these new cutsie Kabotas with plastic and stamped sheet metal all over them are going to be doing 50 years from Now???
