Ok heres the deal, while driving the voltage gauge in the truck will just jump down to about 10 volts from its normal 14 volts. Originaly I though it was happening when the external tranny cooler fan kicked in. Now that I have a tranny temp gauge I know thats not whats happening, and today on my way home it dropped down to 10 and kept falling till about 8 volts. If I stop, turn the truck off and restart it, the voltage goes back up to normal. I'm thinking its a bad voltage regulator. Anyone else go any ideas?
Results 1 to 10 of 10

Thats what I was thinking, just put new wires on it all and probably make all the ground wires bigger while Im at it too. I'm sure the factory stuff would be straining with the plow, light bar, stereo..... all running at one time.
