electrical power loss

[WayneIlfrey]

:--) Hey guys and gals.

I need a little help.

When I crank my 91 up in the morning. I seem to be getting an electrical power loss untile she warms up. The battery meter will fluctuate from 18 to 8. When it does my headlights go dim for a few seconds, then it returns to normal. This goes on until the truck warms up. Then there is no problem.

Can anyone tell me what is going on?

Any help would be appreciated

Thanks

Wayne

Grid Haters

Thats just your grid heaters cycling, it's normal. If your intake manifold is below about 60F then the wait to start lamp will light and cycle the heaters. After the engine is started, they will cycle on and off for about 3 minutes.

Turn on the wipers and you can really see the voltage drop when the heaters kick on!
