Starting to check wiring on my 51. (12 volt)
I have changed to a key start from Classic Parts.
Everything works fine except the Air-Flow heater motor and control. The motor runs and the control lights up and works fine on accessories but does not work at all when the engine is running.
Any ideas? I can't imagine why this would be.Should the accessories terminal be hot when the engine is running? The key is in the same position either way.
Thanks
