Re: 98 Chevrolet Truck

Midnite Tech,
Thanks for responding.
The unit was tested off the vehicle, it tested within normal operational outputs. The reason the alternator was changed was because this same problem existed. I am having no problems with starting. All other systems are acting normally, the only thing I have noticed under the hood, is that when the A/C compressor is running, (serpentine belt) the belt jumps up and down between the spring tension pulley and the Alternator. Could this be a weak cell in the battery ? I Didn't seem to have a problem with the lights this afternoon with a fully charged battery.

Any help would be appreciated
