Restoring the 70 Challenger Rally dash
« on: March 14, 2014 - 07:39:58 PM »
Hi all,

I need help, bought a set of OER gauges, new after market instrument voltage regulator, bench tested regulator, all works fine until I plug the small wire harness to the instruments, then I get no voltage out of regulator, just a buzzing noise.  If IVR is disconnected from gauges test lite shows flashing at the out terminal like it should, plug in one gauge then there is no output only a buzzing noise.  Anybody got any idea about what I could be doing wrong?

Thanks to all,

Fred
