Check the fuse link on the alt.wire harness and check your voltage regulator on the alt.

Replace your voltage regulator on the instrument cluster. Spray a little contact cleaner on a q-tip and coat the module contacts and the copper connections in the cluster.

Not sure how that works but wouldn't that only give me a false reading and not affect performance?

Do you have a one wire 130amp alternator or a 94-95 130amp alternator? The one wire 130amp alternator don't like to charge at idle.

Upgrade to a 200amp. Make sure you have an inline fuse on your existing one and a 200amp one
