Madcat 9 #1 Posted January 30, 2013 I have rebuilt the Kohler engine on a 1970 Electo 12. I can't remember how the coil and the trigger were wired. A wire from stator goes to the "A" lead on the trigger. Does the "I" lead on the trigger connect to both the coil and "I" terminal (black wire) on the ignition switch. I took pictures and notes before I tore it down by must have missed this connection. Appreciate some help. Share this post Link to post Share on other sites
TT-(Moderator) 1,127 #2 Posted January 30, 2013 Does the "I" lead on the trigger connect to both the coil and "I" terminal (black wire) on the ignition switch. That is exactly correct. If you don't have the Kohler service manual, it's available for download in the "manuals" section here at the forum.

Madcat 9 #3 Posted January 30, 2013 Thanks Terry I have downloaded the manual and it says terminal "I" on the trigger must be connected to the ignition switch OR the ignition coil. The wiring diagram is not clear to me. I'm missing something, because I have the black lead from the "I" terminal on the ignition switch going to the engine but not sure where to put it.

TT-(Moderator) 1,127 #4 Posted January 30, 2013 I haven't been around a tractor with the breakerless ignition in a while..... I'm thinking both wires (one from trigger & one from the ignition switch) were hooked to the transformer (coil) via a double or piggyback connector. Edit: found an old post with a picture of that wiring - complete with the inline resistor Share this post Link to post Share on other sites
Madcat 9 #5 Posted January 30, 2013 Thanks, that picture helps a lot, making up the wire connectors now. I need to correct myself. The ignition switch terminal is "M" not "I". I've been working on this too long, getting confused. Thanks again. Share this post Link to post Share on other sites
TT-(Moderator) 1,127 #6 Posted January 30, 2013 Yep..... "M" is for Magneto (ground) Keep battery power away from the "kill" wire and try to keep the trigger module dry and you have (for the most part) a trouble-free ignition system. :handgestures-thumbup: Share this post Link to post Share on other sites
