Finally got around to working on my charging system. Tried all the manual stuff to get charge but as the gen on my engine is not the one in the book it's complicated. This is what it looks like.
Top red wire is marked "F"
Side cloth covered wire is marked "2"
Big fatty is obviously armature and not seen, 15 deg or so behind the "F" is the "G" spot.
Casing has "D18" stamped into it, i.d. tag is too worn to read other than Delco Remy and 12V
The manual mentions split field generators and I think this is one as it has an extra connection marked "2".
I tried connecting the armature to the field with the engine running (as per the Manual) but all I managed was a reverse current situation (battery V went down)
So I pulled the gen (PITA as you need to pull the comp to get at one of the gen bolts)
Bench tested it. I started with an old way I have...current to (+)armature and ground and it's a fine little motor.
Next I tried the same field test but this time using a drill to drive the gen (aprox 500 rpm)
tried various combinations finally found that by connecting armature to "F" position and bridging "2" to "G" with "G" of course already grounded I was making power...not tons but my drill was getting bogged down (HD mixing drill so some charging was trying to happen).
Looking for input here
I'm guessing the PO just bought something that would fit on the engine but not the right V reg as the one that came with it matches neither the book not has an extra field connection point. As you can see this is an older drive system
Generator is about 19" long with drive attached.
I had hoped to get something of a transit to drop in but the transits in the yard have an offset drive with a different circumference in the 5 hole pattern.
I kind of hate gens and was hoping to install an alt, but with this drive issue I am reluctantly considering working this thing out.
Any kind words appreciated. Patrick.
