emeraldlion Posted April 30, 2012 Share Posted April 30, 2012 So I wired everyting up and she cranked first shot! That was exciting. Very few setbacks. Initial timing set well, and the current cam on the 283 chevy likes to idle smooth around 12-1300rpm. I suppose that is beside the point. Had to use a dwell meter because my tach wouldn't work. I know the JTR manual and the threads say to use a 15k ohm resistor in the blue wire, but the blue wire coming from my tach that I utilized already has a 10k ohm resistor in line. Do I need to switch, or add the extra 15k for 25k total? I have a 1978 280z manual that had air conditioning. With the current wire I am using, with the 10k resistor in-line, the tach pegs at 8k immediately and doesn't let off. No bouncing, no movement, just pegged.
