97roadking 0 #1 Posted November 8, 2010 i got an electro 12 automatic and do not have any spark at the plug,,,, i will be the 1st to say,,,,i know nothing about these solid state motors, can it be converted to a regular points motor? should the wire that plugs into the coil light up the test light with the key on? or even when turning over the motor? the model no. is 1-7255 so i think it is a 1970,, i thought i bought the tractor rite,,,$350.00 and it came with a really solid mower deck,,,, oh and should there be a tag on that deck somewhere with a modle no.? Thanks Bob from Indiana :thumbs: Share this post Link to post Share on other sites
MikesRJ 552 #2 Posted November 8, 2010 The 1970 Electro 12 (model #: 1-7255) originally came with a Kohler 301 engine, which IS a points engine. Take a look at the following manuals, and assuming that is the engine you have on your machine is a K301, you should find your answers within. Your problem may be as simple as a fused or dirty set of points. The point cover is on the front of the engine (on the left side as you are facing the flywheel) under a long, narrow cover retained by two screws. I would check there first. See the first manual below for a picture of the points.

TT-(Moderator) 1,128 #4 Posted November 8, 2010 :thumbs: It's right, Bob....... the correct engine would have breakerless (solid-state) ignition. 1969, 1970, & 1971 were breakerless, and battery ignition (with points) returned in 1972. Click on the link to the tp2379 Kohler manual in Mike's post and you'll find how to troubleshoot the system in that manual. Getting spark at the plug might be as easy as removing the ground (kill) wire to the system (could be shorted), but you'll want to check the rest of it out too.

HankB 16 #6 Posted November 9, 2010 It's right, Bob....... the correct engine would have breakerless (solid-state) ignition. 1969, 1970, & 1971 were breakerless, and battery ignition (with points) returned in 1972. What's a good way to tell the difference? I have an '85 312-8 and '71 Raider, both with K310 engines. Both have the standard size coil and I assumed that meant they had points. My son has a '68 or '69 Electro and it has that smallish coil which I thought meant it had breakerless ignition. Is the coil size a good indicator or should I be looking at something else? thanks, hank Share this post Link to post Share on other sites
formariz 11,863 #7 Posted November 9, 2010 Bob Here are a couple of photos from my 69 Electro12 so you can confirm for yourself that you have the breakerless ignition. Good thing I took the photos, I now see an upcoming issue with a broken wire. Share this post Link to post Share on other sites
jusjeepn 59 #8 Posted November 10, 2010 Bob, It is rare for the coil in your ign system to go bad but not unheard of. The wire leading from the trigger module to the bottom of the coil is a pretty common problem. It develops breaks from heat and age as seen in the previous picture and can cause intermittent problems as well as a no spark problem. This wire is replaceable and really easy to make up yourself. You do have to remove the shroud to gain access to the trigger module. While your in there, check the gap on the trigger module and set it as close to .005 as possible. It will help cold starts tremendously. Also check your coil to spark plug wire. A normal wire will ohm out at about 5-8 ohms resistance. If it's much higher, it can cause hard start problems and no spark. All of this information is contained in the aforementioned manual. I do have extra coils and triggers here if you find you need one. Share this post Link to post Share on other sites
