| I have a weird thing going on with our sprayer. A Miller with a cummins engine. I am getting a low voltage error code at idle which a cummins tech told me was in the throttle potentiometer which we replaced. This did not help. Now when engine is at idle I have about 13.5 volts on the dash. If you turn on the lights the voltage drops to around 11 volts and the engine slows a couple hundred rpm and the error code comes on. I have traced the wiring everywhere and can not find that 2 volt drop with a meter anywhere else. The good news is I have plenty of time to work on it because it rains every day and we can't spray. | |
