Electronic ignition tea20

Hello,
I have installed a new electronic system in my Fergie. Few months back and it has been running well. Yesterday it quit and there is no spark. I suspect it is the unit or the ignition switch. If I run a wire from the positive post at the battery to the positive side of the coil would this eliminate the ignition switch and possibly prove either the coil or the electronics are at fault? The tractor is 12 volt negative ground.
Thank you in advance for any info.

Providing there is no additional resistor between coil + and the switch

Yes that would eliminate the switch from being the culprit. Also check while your cranking it to make sure that the voltage to the coil isn't dropping to low for the module to work. As rvirgil said if there is a ballast resistor in line from the switch to the coil that could also be bad. It depends on whether you changed the coil to a 12 volt no external resistor required coil or not. I have seen several Pertronix units in the last few months that have lasted no time. My dad put a brand new one in a VW and he drove the car about 30 miles and it died and never did crank back. The module was bad. A friend of mine has a pulling tractor and the Pertronix in it was about 10 years old. It finally quit and that's understandable being that old. He put a new one in and he backed the tractor off of the trailer at a show and that was as far as that one made it. He had to change it again. It seems that Pertronix quality control has went to crap.

Ok guys here's one for you. Hot wire from the battery direct to the pos on the coil and still no spark?? Changed coils and still the same. Any ideas??

Have you checked the distributor it's self out real good? If the air gap on the module is right and you don't find anything wrong with the distributor like a shorted wire or bad rotor,etc...I would say you have a bad module. I'm not one to jump on the electronic ignition module band wagon. I tried one in an old truck I had and it left me sitting in the middle of town and I switched the truck back to points. All of my gas tractors run points. A good set of points will cost $10.00-$12.00 and under heavy use will still last around 3 years or more.
