I have an ETQ TG72K12 generator with all of 65 hours on it. The motor runs great but doesn’t produce any voltage. I’ve tried the electric drill trick to re-establish the residual magnetism in the windings and I’ve tried the 12v battery trick. Neither worked so I bought a new voltage regulator but I made a mistake and didn’t take a photo of how the old was connected. Does anyone know how this should look or can they provide a photo? Or, how can I know where the + lead from the regulator gets connected to the coil? Any help will be greatly appreciated. Thanks.

try this video from wen
click here for the wen avr replacement
they show the neg as right or outside slip ring (close to the cover)
and the pos as left or inside slip ring (towards motor or close to the winding)

you might take a red paint pen and place a dot at the pos for future fast replacement after you test the unit for proper power
also check the voltage before connecting to a simple load like a space heater.
set for 59 - 61 hz at not load and full rated load.
click here for the test gear page if you do not have a meter with HZ
the 40.00 usd killa watt meters work ok but a good clamp fluke meter with hz is the best for working on gens!!

Thanks, the WEN video was very helpful. Looks like I had the + & - reversed. Probably toasted the new avr. I’ll try connecting it as shown in the video before I order another one.

if the red was pos then yes it was reversed.
50/50 on that...
or in my case 99% lol!
"if there is a chance for things to go wrong it will!"
you can quote me on that one.
lol!
I always triple check everything.

let us know how it turns out!

yea if you run avr gens, spare parts like an avr and brushes are a good idea.
and every 1000 hours check the brushes.

and snap a few pix before you disconnect any wires, and number mark the wires with that electrical number marking tape.
and that tape will stick to parts if they are prepped well.
