View Full Version : Voltage regulation

The engine & battery service lights came on the display of my 2006 Ultra. At the same time the voltage meter was registering 10 volts. A minute or so later the voltage needle jumped back up to about 14.5 and seconds later the enmgine and battery service lights went off. This sequence has happened a couple of times. Does anyone know what this points toward. Stator? Voltage Regulator? Buddy needs to know.

Could be one of 4 things. Stator, battery, voltage regulator, or cable/ground. Have to work through some basic tests to isolate the problem.

JD has got ya covered. Always check the easiest thing first, battery cable.
