I have 79 750F cyl's 2+3 won't light a timing lite, but when I ground the plug on head I get a weak spark, cyl's 1+4 are just fine. I've changed coil, switched the spark units, pulse gen tests fine, 514 ohms on yellow wires and 516 on blue wires. I even got a different pulse gen and put it in still the same 2+3 won't light a timing lite. Iswitched the blue wire to the 1+4 cyl coil over to the 2+3 coil and wala it lites up the timing lite hooked up to 2+3. It appears to be a problem with the yellow wire that goes to the 2+3 coil. I have continuity down to the connection that goes to the spark unit.
I'm to the point that I just go out to my garage drink a beer and just look at it. I need help! Sulman
