Got the rectifier installed. It will generate power but I have to start by taking a 12 volt battery and jump it to positive side of brushes. The second I touch the wire to positive lead on brush it will start putting out power.

The flashing mag is weak.

To weak to get this thing started. My AC output is 1 volt, sometimes less than that. Not enough.
It is supposed to have 1.4 to 4 AC volts.
There were instructions on the weldingweb site before it went down on how to rewind the flashing mag and what wire to buy ?
I didn't write that down.
Anyone know how to do this. Tom

before going through that, make certain that the dc leads are connected in proper polarity, then start it up, connect a load and flash it, and then give it a good heavy load to grind on for a half hour, then shut it down, let it set for a few minutes, then try it again.

self excitation requires a little residual magnetism. when you blew the bridge, that pumped ac through the field, effectively degaussing it.

Rather than flashing, you could use my other non invasive trick... slap a big magnet on the outside of the exciter, move it around till the 75w lightbulb you plugged in starts to glow, and then plug in a 1500w milkhouse heater set to half power, and let it work. it'll rebuild that residual in a half hour our so. Safe and easy.

I am not sure I understand how to do this ?

The only magnets I have are the ones I remove from old computer hard drives. I work on computers as a side job and found the magnets in those larger desktop drives have very strong magnets.
Any pictures on how exactly to do this ?
You saying I don't need to flashing coil to make this thing kick off ?

I am not quite sure how to go about doing what you mentions ?

I do understand the first step you mentioned. I will try that tomorrow with my electric heater and see if it works.
The second method I am not 100 % sure on. Anyway I will report back how it goes.

Just take a stack of those computer magnets... stack them all together tight, so they're one massive fistful, start the generator, with an old-fashioned light bulb connected, and put that magnet against the generator frame. Move it slowly from one end to the other, and when you see a glow in the bulb, LEAVE the magnet where it is...

dkamp, your first tip worked like a dream. I flashed it with a 12 volt battery.

Plugged in my electric heater and let to run with heater on wide open for 30 minutes.

Turned it off and let it sit for 15 minutes.
Started it back up and I did not have to flash it this time.

I even welded with it for 10 minutes. THANKS so much. Never would have got it going if not for you. Its old like me but still works. Tom
