Im looking to buy my first welder a lincoln Ranger 305G the engine runs but there is no voltage output. I know how to check for output with the engine alternator, but i don't know how to tell if the PC board is faulty. If its neither the PC board nor the Alternator im guessing it should be something simple and not too expensive to fix, its just a matter of figuring it out. I really want a Ranger 305G but i don't have the 5 grand to buy a new one. If i can get this thing up and running for under 1,500 it could change my life once i pass my 6G. please help me
