Can't Turn Field Off / Runaway Voltage

Postby brian on Mon Oct 01, 2012 2:31 pm

When I first start the engine, the error indicator show that it can't turn the field off (1 sec on / 1 sec off). Then it will display runaway voltage (6 sec on / 3 sec off).
All the voltages look nominal except the field voltage goes from approximately 12.4v with ignition on not running to about 16 volts when running.
The temperature sensor seems to read a little high at 3.1 volts.

I disconnected the temperature sensor and got the same results.

Tell us what the problem was. That will help others later when they have the same symptoms.

Thanks.
