Hi there I've got a blue star 180 that I bought which the previous owner replaced the orginal engine with a harbor freight predator engine. My question is what can I do with the wire that hooks up to the rectifier since a pred doesn't have an alternator ?.? And what is the voltage required on this wire I believe it is # 50.
can this be bypassed?

Reason: Additional info
The predator only has one wire coming off the charge coil it is electric start with a rope backup. Did not find a ser on the welder but the wiring dia under the cover is # SC-147 173
the welder is not producing any output at the plugs or the weld output. And I'm thinking that this might be the problem and is there a way to bypass this???
T1 is an AC coil. thats looking for the input from the charge coil in the engine. Not entirely sure how you would mimic that
Now that charge wire (which goes to #57 on the 180K), has to go to a rectifier. You will ahve to dig out the other side of its rectifier, as #50 has to go to it. Otherwise you will have to mimic the 18Vac to RC1-3&4 from T1 isolation transformer.
You may get away with going direct to RC1-3, 4 with 12VDC. Won't matter on polarity. Output will be reduced, but it may work.
I use tech manuals not owners manuals, so your #'s mean squat. Thats why I use your serial#'s
