OT Electric Gauges on Dodge pickup

Posted by Frank on February 24, 2002 at 20:06:35 from (206.104.30.123):

This is not a tractor question, but I see a lot of the fine folks on here can solve most any problem.
The oil pressure gauge on my 94 Dodge will read higher when the headlights, or any other electrical load, is on. It will peg the gauge if the lights are on and I operate the power windows. Also when I do this the tach needle drops to zero. When I release the switch the gauge needle drops back and the tach needle returns to normal.
This is the strangest thing I've ever ran across.
Any ideas on what's causing it and how to fix it?
Thanks in advance
Frank
