My setup. I believe I spec'd a 1973 Chevy, 6 cylinder alternator....as I had a 73, V8 Chevy pickup, as a teenager and didn't remember it having a external voltage regulator--and I had to mechanic on it all the time-LOL! My thinking was the 6, would have a lower rpm range. I went thru the suggested checks..BAT at alternator and #2 terminal are hot all the time/switch OFF and battery hooked up. #1 terminal was around 10.5 volts, with the switch ON, no voltage with switch off. On the cluster, the BAT wire from the alternator goes to the - side of the amp gauge, voltage from the battery goes to the + side of the amp gauge. The "red" wire pictured goes from the open side of the switch, thru 11 ohm resistor and also now a 12v LED light(have tried with/without LED before) and runs to terminal 2 on the alternator. I found no resistance in the LED light, so thought I'd give that a whirl. IF I cut the switch on, amp meter moves slightly to discharge, headlights, tail light on...moves further to discharge, with the tractor off. My Super A doesn't have a water pump, alternator is driven off the fan pulley(new, aftermarket) and the crank turns the fan. I purchased the "kit" that included brackets to mount the alternator. Maybe I did get alternator of the wrong year. I dropped alternator pulley size down anyway, from a 2.6 to a 2.3 overdrive pulley. We have an optical tach at work and was going to borrow to see exactly what RPM the alt. pulley was actually turning at high/low speeds.

Today's Featured Article - New Hitches For Your Old Tractor - by Chris Pratt. For this article, we are going to make the irrational and unlikely assumption that you purchased an older tractor that is in tip top shape and needs no immediate repairs other than an oil change and a good bath. To the newcomer planning to restore the machine, this means you have everything you need for the moment (something to sit in the shop and just look at for awhile while you read the books). To the newcomer that wants to get out and use the machine for field work, you may have already hit a major roadblock. That is the dreaded "proprietary hitch". With the exception of the
