Voltage regulator conversion

[animal]

Long time since I’ve got the 126 started, life got in the way and she’s been stored outside for awhile. I’m currently rebuilding the starter generator, and the regulator is a fried Chinese thing. Has anyone used a solid state from a HARLEY FL 65-69, XLCH XLH SPORTSTER 75 76 77?

Well since Harley able is not a starter/generator system, I would think it would not workie at all,
but you can try anything ---- once

Looking at the circuit it should. See pg 1-29. Why don’t you think it’ll work, what am I missing from the schematic?

Ok,
IIRR the Hardly was a 12V gear driven gen with conventional mechanical reg.
and it was an electric start so the amp output of the gen was a little higher than
the kick starts.
What i don't remember is if the amp output was similar to to the output of the cub start/gen.
The new Hardly reg being an upgraded solid state replacement, would be a good choice If it is compatible.
You could try it but if it lets the magic smoke out, it is a junk.
I would make sure if you are willing to chance that.
Make sure you have the Field excitation, Armature and batt terminals clearly sorted out.
Remember on a generator you are varying the field ground to produce charge.
Now you got me to thinking, if you go for it, do let us know how it goes good or bad.
"Coop" here likes those DB electrical guys, so why not contact them for their take
but you need more than a salesman for a good answer.

This one is rated at 15amp and 12v. I’ll have to cut off the connector and download a schematic to determine wiring

I’m getting the specs from here

What about something like this?

[animal]

Cubby102, I looked at that one too but ruled it out because it is an “A circuit” and Cubs need a “B circuit”, but truthfully I need to research the differences. I also have concerns about being D+ connected to the shell as seen here:

Cubby102, I dug into the “A circuit” vs “B circuit” in my old books and I was mistaken. The "A" type system controls the output by regulating the field circuit to ground. The "B" type system controls the output by regulating the battery to field. I had them backwards, so I’m going to order the Bosch 30019 and post back in about a month. I’m in the middle of moving garage and shop around as I’ve got another building going up on the property around the end of August

In the remote chance any of the mentioned VR's would work.. Are they cheaper than after market cub vr? easier to get? DB Electric has them for 21$ WIth my amazon prime account I can get one for 24$ including next day free delivery.

Your money your tractor. Just seems like a lot of time will be spent figuring all this out and whats the payoff?
