Much Thanks to Paul R. Breuhan [prbreuhan@hotmail.com] for his screening
services, I now have an accurate 8000 tach in my Tiger.

I used the original gauge's class, outer and inner bezel too. This takes
about 1 hour worth on modification to the autometer's case.
Now a question for you all -
I am having a problem with the needle jumping around when the engine is at
idle. Once the rpm is over 2000, it reads correct. When I turn on the
lights, at idle, it settles down a lot but still twitches. Sometimes when I
start the car it read the correct idle for a few seconds and then starts to
jump. I called the AutoMeter tech line and the guy thinks that I have a
ground or 12v power issue. He suggested that the alternator may have a bad
diode and is causing voltage problems at idle. I tried using different 12V
sources with no fix. I also tried different grounds with no success.
I am also using a accell electronic ignition kit in my distributer.
When driving the car, the tach works perfect......until it drops to idle.
Any advice as where to start?
