Ammeter to Voltmeter...who does it?

I replaced the amp gauge and did the bypass, then installed a new disassembled sunpro volt gauge in the cluster... Wired it to the fuse block for positive and the other wire to a ground bolt.

It worked fine for a couple days and then hit 18volts maxxed out and will not move. My volt meter says 14.5 running and 12.5 key off.

Okay, bad gauge. Ordered a Bosch replacement, looks almost identical to sunpro. Installed that making sure not to ground anything out to the cluster.

Before buttoning up the install, attached the cluster and tested the gauge. Read 12 v in accessory, and 12v IGN on. Ok, it works. Go have a beer, come back and test it one more time before tightening up the screws and steering column bolts...

Nothing. Kaput. Removed gauge and tested it in the battery with two jumper wires. Nothing.

I have two dead volt gauges. One stuck at 18v and the other at 8v. Great.

3rd time's a charm or should I give up and smash everything?
