Odd problem.

[sendero]

Last year I had the dreaded ammeter meltdown. Over the winter I put in a new dash harnness ( Year One). When I started the car and running on idle. All the gauges showed good. ( I did bypass the ammeter by splicing the wiring connections). When I started to rev the engine up to 2000 rpm..all of the sudden the gauges dropped slowly to zero. When I stopped at a light and went back to idle, the gauges started moving up too steady state. Light turns green, start accelerating.. the gauges drop back to zero. I thought my digital dash assembly voltage regulator may have been at fault. I changed that to another.... same problem.

Anyone run into this before? Very odd.

by the way the dash voltage regulator ( old one and newer is rt-engineering solid state voltage limiter)

Had same issue bad dash ground. Check all the grounds and make sure they are tight and clean.
