(quoted from post at 15:52:13 06/12/22) Got a 9N 42, EI, 12V where I'm not getting spark, just wondering what's first checks for me to do to get it running again. It did seem during winter (here in Michigan) that the tractor seemed to lag, maybe a a timing issue, but guess I'll go with the no spark, no run issue for now.
I personally went to 12v system simply due to the availability to accessory lighting and giggle parts. 12v coolers, 12v lighting, you get the idea. 6v did not offer the supper bright lighting that I wanted. my reasoning is to follow.
I am a heat causality. Bad. Multiple outs due to stupid kid bravery. (read that boy chute and you will be right. all the way arround.) and if I want to work in my shop or anywhere in Texas summers outside, I have to do it at night and have fluids and a fan close by. read that 12v to find anything.
so now, I will drive my tractor out where I am to work on my property, set up two 12v flood lighting, my little fridge, yes I know I could use ice, but have you ever eaten soggy bread on your sandwich? and then I have to buy ice every day. this way I plug into the alternator, lighting and all, and do what I am going to do. if I get shaky, I unplug and roll home, usually not far, but still, you walk when shakes from heat and see how you like it... hehehe... I cool off with the fan if needed, and cold water.
I hate being weak, but hey I can still bring home the tree to build the fire. :?
the Pertronix I put in my was at first bad off the shelf. it had a dwell gap of size enough to drop a thick coin in, and pertronix told me I was insane. I ran there checks, even sent them a video of me doing it to make them believe me, then made it adjustable gap. closed it up to about .030-ish and boom off Chugg went. Yes, his name... live with it. I left the switch on as well, Took it about an hour in my case, and no start after that. DANNNNNG it. I knew what I did right off the bat. as of now, I have 100+ hours of smooth running, most of a year ish, + the idle time on top of that of great running somewhat efficient, 0 resettings run time. not somthing I can say about my more modern tractors. These things are grease, check oil and gas, and go. every time. My vote for EI....
