Snoopy11 5,714 #1 Posted July 12, 2022 Good evening my good people, Some of you know that I am rewiring a 416-8. WELL... both wires coming from the charging system are yellow... much like this: SO, I just want to make sure of something... and that is: I want the yellow wire with the diode on it to go to battery positive power... correct? And the other yellow wire is for the lighting system... correct? I would appreciate any advice/reassurance that you guys can give! Don Share this post Link to post Share on other sites

cafoose 3,355 #3 Posted July 12, 2022 I'm almost positive both of those yellow wires go to the voltage regulator and carry 30 VAC. The one terminal on the voltage regulator is +12 VDC. This diagram is for a points ignition. Magnum with no points is different. 1 Share this post Link to post Share on other sites
cafoose 3,355 #4 Posted July 12, 2022 Magnum no points. DO NOT let battery voltage on white kill wire or magic smoke will appear regulator is wired the same on both engines. 1 1 Share this post Link to post Share on other sites

And the other yellow wire is for the lighting system... correct? That looks like a rather small stator. Might be a low amperage single wire charging system. If you happen to have one wire with a diode, then you are probably correct. 1 Share this post Link to post Share on other sites

I convert all my machines to the 15 amp system with the voltage regulator. 1 Share this post Link to post Share on other sites
953 nut 55,224 #7 Posted July 12, 2022 You didn't give us a year of manufacture or model number to go by. Nor did you give an engine manufacturer name or model. Lots of wiring changes were made over the years but the one thing that remained relatively constant was the charging system. Here is the wiring for the charging system on a 1989 416-8. It is common to most models of that era with the exception of some 310s. The fact that both wires are the same color should have been your first clue that they can be reversed without any consequence. 1 Share this post Link to post Share on other sites
Snoopy11 5,714 #8 Posted July 12, 2022 Hey guys, I appreciate your input. This is a K341 engine. The tractor itself has no tag... it appears that the PO removed the tag on the tractor. One of the yellow wires coming from the stator has a diode... the other yellow wire coming from the stator does not have a diode. Don Share this post Link to post Share on other sites

pfrederi 17,739 #10 Posted July 12, 2022 WH used 2 different spec numbers for 416-8 71371 used in 1985 had the 3 amp system no regulator just a diode.... in 1986 the 71381 had 15 amp with regulator 2 Share this post Link to post Share on other sites

cafoose 3,355 #12 Posted July 12, 2022 K341 should have points especially if there is a round coil with a wire going to the points and a removable spark plug wire. If it were me I would get a 15 amp stator and regulator and wire it up like this: 1 Share this post Link to post Share on other sites
953 nut 55,224 #13 Posted July 12, 2022 The photo you used to show the stator isn't your engine is it? A photo of your stator would be helpful. Being a K-341 and presuming this is the engine it left the factory with that would be a 1985 or 1986 model. If it is a 1985 model it would have the diode and less robust charging system as shown in the first drawing. spec # 71371 If it was a 1986 it would have had the 15 amp charging system as seen in the second drawing. spec #71381 This information should help you find the parts you'll need Share this post Link to post Share on other sites

I did pull the flywheel and looked, it looks like the initial picture I posted. I didn't happen to get a picture of it before I put the flywheel back one... I guess I could pull the flywheel again...
