John Deere 850 - Yanmar 3110D
Morning!

My 3110D did not have a voltage regulator when I purchased it. Getting tired of jump starting the tractor, I bought the new solid state voltage regulator.

The wiring is all present, but some wires near the alternator are disconnected. I'm not quite sure where the wires go, & I sure don't want to fry the new regulator or the alternator or battery.

Does anyone have a wiring schematic for the 3110D electrical connections?

Thank you!

Try this.336 so it should work. The Alt. # is AL-1235. And shows the 336 & 3110 Lucky I found my Org. I have clearly marked 336 And luckly I can make out the markings somewhat under a loop. I guess your after the wires to the ALT. & Reg. E-BLK. N-White Red. F-White Blk. A-Blue.

This should be the wiring for the alternator itself if you need that too. The N & F would go to the regulator.

I have the John Deere tech manual for JD 850-950-1050. Would the wiring be the same as those models?

Careyo63's image is a little hard to read wire color names.

Here's the schematic from the JD manual:
