rdeanrj58 68 #1 Posted June 14, 2020 I’m installing a k301 off of a 312-8 on to a B-80 I would like to use the regulator and amp gauge from the B-80 but don’t know if it’s compatible with the stator on the 12 hp. I’ve looked at Kohler manual on how to test stators but I don’t know what amp stator I have Also I think the 312-8 had a volt gauge which further complicates matters Share this post Link to post Share on other sites
953 nut 59,338 #2 Posted June 14, 2020 Depending on the year 312 it probably has a voltage regulator mounted in the flywheel cover. You would be much better off using a volt meter rather than an amp meter. If your B-80 has a battery powered ignition system and the 312 has a magneto you will need to ad a relay to the ignition system. Share this post Link to post Share on other sites

If he has K-301 like he posted off a 1985 312-8 it has a battery and points. 1 Share this post Link to post Share on other sites

Lee1977 7,144 #5 Posted June 14, 2020 He didn't say a 1985, but he clearly said K-301. Share this post Link to post Share on other sites
rdeanrj58 68 #6 Posted June 14, 2020 The 312-8 I had was I believe an 85or 86 I think after that they were magnums. Mine is a k-series Share this post Link to post Share on other sites
The Tuul Crib 7,339 #7 Posted June 14, 2020 Yes I do believe the magnum came in about 1987 maybe as early as 1986 pre. My 312-8 was a 1986 model and that was a K-series motor. 1 Share this post Link to post Share on other sites
rdeanrj58 68 #8 Posted June 15, 2020 I’m retaining the bat/coil ignition. I’ve had it running but haven’t hooked up stator yet. Just want to be sure the stator and regulator/amp gauge are compatible Share this post Link to post Share on other sites
