This one seems a bit odd to me. I have a 92 K1500 silverado with a replced Goodwrench 350 TBI engine. The battery gauge dropped to the red zone and the baterry idiot light came on. So my first step was to take the battery back to Auto Zone to be tested. In a happy turn of events the battery was actually bad. However, when replaced, the gauge did not immediately return to the normal ~14 volts, but after a few minutes it did and the drive home was uneventful. I'm thinking I got off without a problem in the charging system. This morning the gauge is back in the red, and the idiot light is back on. I don't no much about such things. I tried to tighten everything up. Is there something else I should look for? Is their some sort of sensor that could be bad? This is the original alternator and voltage regulator. I'm not real flush at the moment, and need the thing to get to work. I do have a trickle charger. Can I keep a charge on the battery and gather another paycheck before dealing with it?
Thanks for imput Rick
