Well, I guess I have joined the "Red power" set. I happened on a street sign that said "Farm auction" and turned in to see. They had 17 tractors and a gazillion implements plus u name it. 3 were Farmall's, a super C in beat up and bent shape that went for $200, an MTA that they said was 'stuck' and had been for over 20 years, it went for $100. I saw a busted tranny case, bent pto, and a hole in the lower front crankcase. The third one I bought. It is a 'restored' A number FAA 103,333. It was purchased new by 'gramps' and had been on the farm (Grantsville Utah), since new in '44. I got it for $900. They had sent the engine to IH for a complete overhaul and I got receipts for new crank, cam, valves, guides, rocker assy., manifold, carb etc. It has an adjustable front, new gen, starter and Vr, light and mag switch, short stack with spark arrestor. It has an IH Magneto, belt drive pto with an extension and chain drive sprocket and shutters. There was no wiring harness, lights, battery, battery box, tool tray, draw bar or anchor bar. The tin is perfect. The gauges appear to be original and the scales are not legible but they work. I put a wiring harnes in it and a battery. A couple of gallons of gas and it started right up and runs as smooth as the perverbial babies posterior. It immediately sprayed water from the radiator core and I found a bullet hole. A local shop fixed the nicked tube without having to seal it off so other than an ugly place on the front of the radiator, (behind the shutter) it now runs at about 120 to 130 degrees under full belt load. Oil pressure, (with a different gauge) holds at 45 pounds at high RPM and 10 pounds at idle-hot. Unfortunately I have to drop the drives and put new brakes in and find the missing stuff. But I am now in love with it.
By the way, it wouldn't charge and I have some info for anyone else with the same problem: There is supposed to be a jumper from the field post to the field connection of the VR and with the wire to the switch disconnectd it will charge at 3-4 amps to a low battery. If the switch is CCW and connected, (off) it will charge at 6-8 amps and lastly, in any other position of the switch it will charge at 16-18 amps. This is because the resistor in the switch is parallel with the one in the VR and that increases field current. In "on" the switch shorts the field to ground for max current which is set with the third brush. The spring in the VR is set for 6.9 volts + - 0.2 Volts. Remember that higher charge volts boils battery water away and dead batteries freeze. BTW the resistor at the switch is the same as the one in the VR and available from Delco. Mine had dirt and spider webs in the gen. and a bad ground at the switch due to paint. I ran an extra wire from the switch ground to the tranny where the battery + cable connects and it is fine.
If its Red stop and look, if its green go on by.
