OK, I'm confused.
Setting the timing on my 87 tintop. Just installed a new Accel super coil day before.
Try to hook up my dwell-tach meter to measure idle speed, black clip to ground, red clip to positive + terminal on ignition coil according to instructions... Doesn't work. Red clip to negative - terminal on coil, it works.
Think, hmm, polarity is reversed. Examine more closely; have a brown wire going to the negative terminal, black / white stripe wire going to positive.
Get out multi-meter. Detatch wires from coil and measure with ignition on (but obviously engine not running). Black/white stripe has 12.7 + volts to ground. Brown wire has fluctuating + .0 to + 3.3 v to ground.
Turn ignition off, check to see if either wire is grounded, Nope, neither wire goes directly to ground.
FSM and Haynes of no help in determining which wire goes to which terminal. Nor does a search of all the Suzuki forums.
How do you determine which wire goes to which terminal? Is it possible that the factory polarity markings on the coil are reversed?
Or does it even matter?
