Hi.
I have a Rally 266 which have no turning of the wire wheel and no welding power. It does open for the gas.
I have checked the wiremotor is running by applying 10Vdc from a power supply.
No fuses is bad.
28 vac from small transformer is ok.
All 6 power diodes measures ok.
I don't have the schematic of the pcb, so it is difficult to troubleshoot, but nothing looks bad.
A couple of month ago I replaced the potentiometer for wire feed, and it has worked flawlressly since, until last week.
Any hints or maybe a schematic of the pcb.
Thank you
