Golden Jubilee Firing Problem

S. Byrd · May 5, 2011

We were fortunate enough for a person directing us on the proper firing order and posting a picture of the correct installation of the wires onto the cap. We have checked all the things to look for and still cannot get it to fire at the points. So, I have one other question - Does the wire from the distributor go on the positive or negative side of the coil?

Thanks for any help you can give us.

before worrying about the wire, check these out, 1 that the rotor fits tightly on the distributer shaft there is one rotor which looks identical to the one used on the jubilee but, the drive hole is bigger, allowing the rotor to simply sit on the shaft and not turn, secong check the wires going to the points themselvs, bet you a doller, you'll find one of them touching ground,also check for a grounded wire where the wire goes thru the distributer body, is the jubille still 6 v or is it a 12 volt conversion, if its 12 volt, ill go look at mine as soon as the sun comes up for you on the coil wires

If negative ground system the distributor connects to negative coil post. If positive ground the distributor connects to positive coil post.

If connected backwards it will give a slightly weaker spark, but will still fire

It depends on how your battery is grounded. If you still have the 6 volt battery they were all positive grounded so the positive terminal on your coil should have the wire going to your points.

If you converted your tractor to 12 volts your battery is negative grounded and the negative terminal on your coil feeds voltage to your points. Have you used a volt meter or test lite to see if you have voltage at yor coil? With the points open you should have battery voltage on both small terminals on your coil. You need the ignition switch in the on position too. If there's no voltage here you need to check back at the switch for voltage. You may have a bad switch or broken wire if there's no voltage at the switch. Run a separate wire from the battery to your coil and see if the engine will start. This will bypass your switch. Rub those points with some 320 wet or dry until shiny. Hal

You say you dont have fire,but what did you do since you last had fire? Did you ever have fire? Get a test light,check from the ignition switch to the points and see if it lights the test light to there.If you have power up to the points and no fire,then you are either loosing it where it goes through the distributor or somewhere.If you dont have fire from the switch,that tells you its the switch.There could be other things wrong,but that would be a start. Also,how did you test to see if you had fire? You can use the test light on a plug wire by sliding the probe up under the boot until it touches the brass on the plug and see if its firing.

Did you check the wire going into the distributor from the coil. That wire passes through a insulator and then to the copper strip that attaches to the points. Make sure the insulator isn"t cracked,..that would cause a short,..thus no spark at the points. Also check all your connections in your electrical system to make sure they are clean and tight,..i.e battery terminals,ignition wires,coil wires,v.reg wired correctly,.ect..

Besides the shorts in the pass-through insulator area it's common for the copper strip to crack/break causing an "open".

The coil will work ok no matter which way it is wired but it will be a tad bit more effective if wired with the correct polarity. So if you ground it + you want the side of the coil to the distributor and if - ground that side to the distributor. I would hot wire it and see if you then have spark at the points when you open and close them by hand. You should both hear and see them spark when you open and close them. If no sprak then take an ohm meter and check for grounds. Make sure the points are open when you do that. You should read an open circuit with the points open and the coil unhooked from the distributor if no open then you have a short in the distributor and that is why you have no spark
