460 coil wires

put electronic ignition on 460 today. It was wired for the points with a black switched wire and a white wire on the negative terminal of coil and the wire going to distributor on positive terminal. The ignition instructions said to have red wire and switched wire on positive side and black wire of ignition on neg side. Where do I put the white wire? It was not starting with the white wire still on the neg coil terminal but it started and ran fine when I took wire off. Do I put the white wire over on the positive side or does it belong somewhere else?

Are you sure the white wire is used? Hal

Im cornfused about what you had to begin with when points were used???????

Id expect a single SWITCHED wire down from the dash Ignition switch which was, or course, hot ONLY when the ignition was on, i.e. its SWITCHED and its connected to the high input (NOT distributor) side of the igntion coil.

Id expect a single wire on the coils other side wired to the distributor.

NOWWWWWWWW in the event the tractor was 12 volts but used a 6 volt coil, it may have been equipped with a start by pass circuit consisitng of an extra third wire BUT such a wire would connect to EITHER the coils high input side (i.e. 2 wires on coils input not just 1) or the low output side of a ballast resistor.....

NEXT a normal electronic switch set up would only need 2 wires. One (say red) wires to the high input side of the coil, the same place where the switched wire down from the ignition switch connects.........The other (say black or white) wires to the low output side of the coil.

Those three wires have me cornfuzeddddddddddd

MAKE SURE YOUR ELEC SWITCH MATCHES THE TRACTOR POLARITY (pos or neg ground) or you may fry it and to get the most bang for the buck and utilize all the advanatges that elec switch has to offer ID MATCH IT WITH A HIGH ENERGY HIGH VOLTAGE COIL and run a wider plug gap if it were me.....

PS go with that the vendor says, not myslef or others here, cuz youre dealing with an expensive switch and I dont wanan see you fry it cuz we told you wrong

It's used, there is one on my 460 -- have to look at wiring diagram to see what it is for, though.

I looked at a Pertronix kit when doing a search and it had only a red and black wire showing. Hal

Probably not needed with that system, With a coil and distributer it goes from the starter switch thought the ballast resistor to the + coil terminal. My coil has an internal resistor, I still hook up the wire, don't know if it is needed though.

There were two wires on the coil high input side. The switched voltage wire and this mystery white wire. The tractor has a 12 volt coil and is running 12 volt negative ground it has a generator. I do not know if this is how it started it's life. It has been around the farm for a long time but not hardly used until this summer I took an interest in it and am trying to get it tuned up. It is a good running tractor and everything is pretty much original but the original voltage could be a mystery.
