Voltage Regulator

[SKelly]

You guys are to much help! On the way home today from a Quick Lube oil change my voltage guage dropped off and the check guages light came on. A quick search on "voltage regulator" brought my attention to the 140 amp fuse which was blown by the oil guys shorting out the alternator somehow. Many thanks to the best diesel website.

Here's how they shorted out the B+ on the alternator—and the fix (thanks Dave Fritz):
