I just installed some Autometer Sport Comp Digital gauges (the two on the right):
I get 12v dimmable power for the gauge faces from the positive ash tray light wire BUT unless the dimmer is all the way up, the voltage wavers a little (according to my multimeter). The wavering voltage causes wavering brightness on the gauge faces, which is distracting. Note that voltage from the fuse box is rock solid.
Autometer thought it might be a bad ground, but wouldn't that make the fusebox voltage waver as well? Is the ash tray wire too small? Is there a beefier wire I can tap for more dimmable current?
Thanks for any input!
(Sidenote: the wideband sensor is not hooked up yet so the gauge pictured is just making up AFRs)
