miller bobcat 225 SN MD011240R starts and dies, power to the fuel shut off solinod only when cranking. I have checked the #1 and #2 fuse ok, bridge rectifier 1 and 2 are good. main diode is good. by passed oil switch same thing. does this circuit get its power from the hour / idle control meter?
Thanks

Not sure if this helps, but I dis connected the wire at the carb and installed a jumper to 12v runs fine, but idle solinoid wont engage and it runs only on fast, no welding current at the output.
