Picked up a Winpower 6/10 PT2 generator last week. Didn't pay much which may be a good thing.

Hooked it to the Super A today, and I only have 8.2V at the AC outlet.

I took the rear cover off and the contact rings look shiny enough. I don't think that's the problem.

Probably needs to be "flashed" but I can't find ANY markings on ANY wires, let alone the F1 and F2.

Any help on what I'd be looking for? Is it under the rear cover or the panel?

I found the parts book on Winco's website, but it's no help.

The exploded views are CRUDELY hand-drawn, and I can't tell the armature from the PTO shaft!

What they label as the "shunt rectifier" is drawn as a white rectangle. I looked all over inside the generator and there is nothing that looks like a white rectangle!

Nothing inside the generator is labeled, and all the wires are either white or brown.

Anybody got any ideas at all here?

I tried the drill trick, even going so far as to drive the corded drill backwards with a cordless. No dice. Output is only 5.2V now.

I've got the back cover off and I can't tell where the shunt rectifier is, or which wires are F1 and F2.

if i remember right,the drill has to be a dc for that trick.
only other thing i can think of is look at the brush holders...the ones that are insulated should be positive.

I think I found the shunt rectifier, and the problem.

The diodes were there in spirit only. As soon as I touched them, they crumbled and fell off. Looks like a trip to Radio Shack is in order.

Nope.

I got a new rectifier from Radio Shack and plugged it in. Still no juice.

I tried applying 12V to what I *THINK* is the F1 and F2 connections. Still no juice.

The big problem is that NOTHING is marked in this generator. All the wires are either white or brown.
