2nd Gen Non-Engine/Transmission charging quesion?

[GOTSOOT]

This last week i have noticed that the alt. gauge is slow to move up to the normal range. I had the battiers and alt checked , and they are good. Cleaned all the connections and still is slow to move up. Could voltage reg. be going south? Don`t want to get stranded!!

Did it move faster before last week? It sounds normal to me, as long as it is charging. I'd keep an eye on the batteries and check the voltage everyday both with the engine off and with the engine running. Check the voltage as soon as you start the truck. You should get a reading of 14. 4 volts. If not, you may need an alternator.

BTW, the voltage regulator is part of the PCM so I doubt that's the problem.

When I start mine in the morning, I've noticed that the needle is slow to move up to the 14 range. I've always attributed that to the manifold heater doing its thing. Once it gets warmed up, the needle is right where it should be.

You mite want to check out your Battery temp sensor/connector under the driver's side battery tray.

Is that what that is???? I was wondering what the heck it was for.
