I have a retro fit 10 SI alternator on my 806. I found the external regulator was still on the tractor with all the wires disconnected, so it shouldn't be affecting anything.
I had posted on the forum here on 12/15 about my alternator heating up, then not charging at all. Based on the information I got in responses I got things hooked up and my alternator was charging perfectly at 14 volts into a single 12 volt battery and not heating a bit. I really appreciated the help. But I still have problem that showed up after it sat a couple of days. The battery was pretty well drained.
The picture is how I hooked it up.I got a few extra ones in there of the same thing. That 10 gauge wire goes directly to the battery.
I do not have the diode in it yet. I have them ordered but wired in the idiot light for now.
The drain occurs when I hook up the sensing wire from the output post to the #2 spade of the internal voltage regulator. With that connected I get a full 13 volt discharge, checked between the neg post of the battery and ground. Taking that wire off the regulator spade stops the drain. The "exciter" wire isn't affecting anything.
I thought maybe the alternator was bad even with a new regulator, but it checks out fine at an auto parts store. I'm sure it's something I have crossed up, but don't know what it is. I can run the tractor like it is and just disconnect the ground strap, but getting it working would be better.
Appreciate the help, as always, Bob
