JRess 12 #1 Posted April 10, 2023 I have a 12hp Koehler 301. The spark plug cable boot is worn. I have a new cable. How do I replace into the ignition coil? Since I am not too mechanical inclined don’t want to break anything. Thanks all. 1 Share this post Link to post Share on other sites
WHX?? 46,868 #2 Posted April 10, 2023 Just pull the old one straight out. There should be a metal looking ferrule on the end of the old one and the replacement should have one like it on it. Just push it in. You should feel a slight click when it connects. 3 Share this post Link to post Share on other sites
WHX?? 46,868 #3 Posted April 10, 2023 Forgot to add look down into the coil socket with a flashlight and check for any corrosion in ther. Clean as required. 29 minutes ago, JRess said: Since I am not too mechanical inclined That's OK I'm no good at making model tractors out of toothpicks either... 2 2 Share this post Link to post Share on other sites
squonk 38,981 #4 Posted April 10, 2023 You can see what the wire end looks like 2nd wire from the left. 3 Share this post Link to post Share on other sites
WHX?? 46,868 #5 Posted April 10, 2023 Greasy Pete @peter lena might suggest some dielectric grease on it? 1 1 Share this post Link to post Share on other sites
peter lena 8,087 #6 Posted April 11, 2023 @JRess would use just a very light dielectric grease swipe , inside the plug boot , insure conductivity and eliminates boot tearing , do that on all my small engines . pete Share this post Link to post Share on other sites

I was just getting ready to complain about the price of a single wire and was looking at some for marine engines as a possible way to buy 6 at a time. I am guessing that is what you did, I just want to confirm they work. Thanks!! Randy Share this post Link to post Share on other sites

WHX?? 46,868 #12 Posted June 2, 2023 He buys begs borrows & steals the pieces from NAPA and has the handy dandy crimper @RandyLittrell. I got one from him at the BS and they are nice but me thinks Ole Sqounky bent me... @Achto and I since buy plug wire sets at Fleet Farm. Supposed to be for a Continental Dan?? Enough wire and ends to make a few. 2 Share this post Link to post Share on other sites

Enough wire and ends to make a few. I hit you over the head with a shovel. The " universal tractor wire sets come with the boots and terminals on one end. You cut to length and put the ends on the other. Old # was Belden 700172. Sold a bunch of them. The problem with the kit is the plug terminals and boots are straight not a 90 deg elbow. That's why I buy everything separate so they have the right end. I'll have to check out Tractor supply. Looks like they sell a kit with the right boots..

These are the ones that we buy, they come with a 90 degree boot on the plug end. They sell 4cyl kit and a 6cyl kit. https://www.fleetfarm.com/detail/calco-6-cylinder-wire-set/0000000026269?Ntt=tractor parts TSC has a similar kit, they are a little more proud of theirs. https://www.tractorsupply.com/tsc/product/tisco-spark-plug-wire-set-sws260 2 Share this post Link to post Share on other sites
squonk 38,981 #16 Posted June 2, 2023 I saw those when I googled fleet farm. What material are the plug boots made from? I'd like to see an up close picture of them. The boots I use are 80% of the cost of the wire I make. Wouldn't mind a cheaper alternative if I could find one. Share this post Link to post Share on other sites
