Does anyone know which terminal on the ignition switch you put the alternator wire on? 12V neg grnd. 4 post ignition switch. I think it should go on the Batt term but I'm not sure.

If you put the alternator to the Bat Term you will only have a conection going to the switch. You need power from the battry also till the altinator is putting out power. Then the switch would only put power to the coil and starter when needed. If you were only powering the coil and starting it that would be fine but you need to charge the battry also and pervide power to the head lights. So you will need to figure a way to power the other parts up. You could power the lights also from the IGN terminal and the ACC terminal is useless for the tractor unless you want to want to power another set of lights to be switched by the switch to work when the tractor is not running. You will need another switch for the headlights unless you want them on all the time. You also need to check to see if this switch is large enought AMPS wise to handle the current of the altinator if you are switching it with it. Most car swithes now days control relays and do not handle the load put to it. Lot of varibles using none stock parts and it all depends on how you wire it and what non stock parts you are using. It will be a custom wiring job figured on what you have. Normaly the switch is used to cut power to the coil only. The rest of the conections are made on the terminal block on the dash. Mark H.

Barry..... ....lets see if my power of mindreading is still working. hummmmm ..... .uh, yeah, ok, uh, 4-terminal auto key ignition switch, um, that would be a non-standard N-Tractor ignition switch installation, and thats ok.

It should have a battery input terminal. An ignition coil output terminal. A activate the starter solenoid terminal. An AUX terminal for the radio to play while you're parked at the submarine races with your sweetie.

The AUX terminal is the one you want to provide a switched external excitation voltage to the 3-wire Delco 10-SI alternator P1 excite terminal. Connect the voltage sense terminal P2 to the BIG battery stud on back of alternator.

NOW that you know what a typical automotive ignition switch is suppost to circuit like. I have no clue which terminal is which. Thats YOUR JOB, and you'll have to figger it out with an ohm meter. Altho there is a remote chance that there just might have been some sort of printed information about the switch innna the box that you've already thrown out. Who knows, ya just might get lucky? ..... ...the mindreading Dell

That would be fine, but you will have to figure out which of the other three is closed all of the time when the switch is on to connect your resister to coil wire to. I'm not familiar with your 4 way switch, but it sounds like an automobile switch which would have auxilary and starter settings that you don't need. If you have a ohm meter, you can check for continuity between the 'battery' connection and the one that opens when the key is off and closes when the key is on. That would be the one to connect to the resister. Ron
