#3196, "RE: Update on the Jumptronix clone" In response to In response to 7
I could probably change out the green LED for a blue one, but considering the effort involved (and possiblility of damage to the unit) I'd rather not. The gage is tiny, 24mmx48mm...I practically need a magnifying glass just to make the connections. I'd hate to see what the inside of the thing looks like. I switched all my gages to green so I was actually happy that the A/F gage had a green LED. Its no problem making the gage read charging system voltage with a switch. You'd have to run a fourth wire up to the gage. I get my gage power from the ECU power. That gives much much more stable voltages for the gage to work with.
