Miller 151s wont feed

[David Halstead]

Have a Miller 151s and the wire wont feed,if I operate the relay manually on the pcb all is fine,cant find any loose components or scorching,I posses a multimeter but don't know where to start,really need a hand

Start by checking the torch switch wires for continuity with the trigger pulled

Hi,checked that first

 

[wheresmejumper]

Did you check it at the board?or switch end
a pic of the relay+board would be next step

Hi,thanks for your reply,the trigger switch was checked and all was good,the welder works great if I manually trip the contactor and press trigger it will weld.i have a pic of the board plus wiring diagram but new to this forum so don't know how to send them to you,might be easier for me if I could have email address.regards David
