I have them on 2 of my cars they work great. Sounds to me like you need to check the factory connection at the back of your gauge. I know on my duster before switching to all auto meter gauges the factory voltage gauge has two connections that if they come loose will make the charging system...
Has anyone sent theres in and had it re coated? does it actually cure the issue? I have mine out right now to have my heads ported and would like this problem corrected.
