12v conversion kit not working

Purchased a 12v conversion kit for my 9n. Had bad wiring in the tractor so I used the new wiring and resistor that came with the kit. Wired the tractor according to the instructions and diagram provided. Tractor will not start - starter turns over fine just no spark. Ran a jumper wire from positive post of battery to the coil - hit the starter button and it started right off. I've looked through a number of posts here but can't seem to find anything addressing this specific issue. Also - I could not turn off the tractor with the ignition switch - had to pull the jumper wire from the battery.

As Dell said.. it's either wired wrong.. or you have too much primary resistance..

but we will need to know what coil and what resistors you are using..

I am using a new 12v coil that came with the conversion kit and a ceramic resistor which also came with the kit that appears to be a .05 ohm. The url listed shows a image file of the wiring diagram which I followed and double-checked after my original posting

Hmm.. something doesn't add up here.

.05 ohms is virtually nothing.. almost just 'wire' resitance for the whole harness.

Generally.. the square 12v coils need .5 ohms of ressitance.. OR the ballast resistor.. but not both..

if it was the oem 6v coil.. you need the OEM ballast resistor AND a dropping resistor like an 8ne10306.

Are you running this ceramic resistor AND your ballast resistor? if so bypass your ballast resistor and see what that gets you.

Soundguy - I stand corrected. The resistor is NOT .05 but .5 ohm

Chuck..... ..why are you surprized to find out iff'n you by-pass the ignition switch by running a jumper from the battery to the coil, you CAN'T turn yer ignition off with the ignition switch???

Lets analyze this. You're having trouble starting yer new-to-you 9N. So in a brilliant burst of electrically challenged creativeness, you decide to fixx 3-problems at 1-time. You doubt? You cite bad wiring, good place to start and STOP. But NO, you don't stop, you convert to 12-volts 'cuz "Bubba" down at the local barley-pops emporium sez' "thats the thing to do". He don't know squats about N-Tractors, but he can talk a good talk.

Now you have a 3rd problem, that you will swear onnna stacka Bibles that you wired your 12-volt conversion per the instructions and now it will only start iff'n you do a shadetree mechanics trick of by-passing all the stuff you claim you wired correctly and it starts. Do you sense a dichotomy here?

Me? I'd check the wiring between the top-post of the squarecan ignition coil and the ignition ON terminal. Use a $5 lite'inna'pick to trace them missing electrons. ...or... you could squander $10 for a real electrical testmeter at yer local hardware store. Simple, eh?..... ..respectfully, Dell yer self-appointed sparkie-meister

If you hot wired it to get it going, I guess you gotta unhotwire it to get it to stop.
You have isolated the problem to what's between Battery+ and coil - ignition switch, ammeter, resistor(s) and wiring - must be one of them. Turn on switch and check volts along the way or use an ohmmeter and check for discontinuities.

If you Bypass the ignition switch with your Jumper it would be very unusual for the switch to operate normally. If you want the switch to work it must be in the circuit.

You need to Spec what coil you are using.

Sounds like you are feeding back to the coil from the alternator instead of feeding the coil from the ignition switch and through the resistors. Check your wiring real well again.

reverse the terminal post connection of your coil wire and see what happens. b
