Saber 15 #1 Posted September 23, 2014 I transplanted a later 12hp Kohler mag into an 86 310. The Kohler has elect ignition and runs perfect. I have 20-40volts AC on the stator leads but no DC on the center DC lead to ground. I replaced the rectifier/regulater to no avail. This should work!!!!!! Any ideas?? Thanks in advance Mark Share this post Link to post Share on other sites
KC9KAS 4,744 #2 Posted September 23, 2014 Make sure the regulator has a good ground. I had to run a wire from the regulator to ground on one of mine Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,393 #3 Posted September 23, 2014 Are you testing this with a good charged battery in the system? The regulators need to see system voltage before they can regulate the current. Some even have a decal stating a battery must be connected to prevent damage to other components. Garry Share this post Link to post Share on other sites
Saber 15 #4 Posted September 23, 2014 Make sure the regulator has a good ground. I had to run a wire from the regulator to ground on one of mine I should have put that in my post, I ran a ground with from the regulator case to the block. The ground made no difference. thanks for the reply KC9KAS Share this post Link to post Share on other sites

Could that be the problem??? Share this post Link to post Share on other sites
WH nut 553 #6 Posted September 23, 2014 Gary: I am testing for the DC without the lead connected to the battery. Could that be the problem??? Are you going from a k series to a Magnum? If going magnum to magnum, you need 12v from the tractor ignition to reg. Share this post Link to post Share on other sites
