Thanks,I have already been to that site and printed the delco 2 wire diagram my first question is the #2 terminal in the sketch shows I guess a jumper wire from that postion to a battery terminal on alter. that I dont have and second question #1 to diode (is this the same as resistor) if so where does wire hook to it currently is hooked to ground and wire from switch to resistor and resistor to coil and the sketch for TO30 12 volt same as 6 volt I'm missing something here Thanks

Is your alternator a one wire alternator. If so you will only need the one hot wire that runs to the back of the alternator. The alternator if one wire is a self exciting alternator and will charge when it reaches a certan r.p.m. I don't have any diodes on my tractor. From the ignition switch to the coil u will have to use a resistor if you have a six volt coil that only puts out i think 1.5 ohms. if you have a 12 volt coil that puts out 3 ohms you will not need a resistor and can run straight from the switch to the coil.

The alter. has 2 terminals with a nut to remove and put wire connector around and put nut back on and tighten on the left side of alter. while bolted to eng. it also has a 2 prong type connection on front upper left corner which had no wires attached when got tractor. the tractor ran and started good until wiring got pulled off by cattle while setting in pasture field over night out of gas I should have shot them then

I would think it's a one wire alternator. On my alternator i have a termnal that hooks up to the positive with a nut. and a screw that is used for an extra ground strap if needed. The 2 prongs are not used for a one wire alternator. I would hook up the positive wire and make sure the tractor is grounded good and fire it up and rev it up and see if it starts charging. Make sure your belt is good and tight. I know if my belt gets a little loose it'll stop charging on me. it is very perticuler. But it was also a cheapo alternator i bought at advanced auto but it does the job. If i was at home i'd take a pick of it for you.

Here's what i do,get a 3 pole key switch or one with ACC i use the key switch for a Ferguson50 it has the extra pole for the lights. #2 prong on alt. run short jumper wire to threaded post then post to key switch. #1 prong on Alt. run wire to key say the lights or acc. Power from key switch run to ammeter - side + side i run to the solenoid. No diode, no regulator needed. Hope this helps ya
