TOY350, baloo
I'm trying to wire the Pro Tach discussed in the recent thread but I keep running into a glitch. Granted electronics are definitely my weak point and maybe I had too many beers before tacking the project, but...
If I use the OEM tach light ground for the Pro Tack unit the dimmer works correctly but the tach signal gets interence somehow and gives an erratic reading when the lights are on.
If I use the OEM tach ground the signal is OK but the dimmer works opposite of the other dash lights.
Isn't the dimmer just a reostat that limits current on the positive side?
