Just want to relate a 'possibility' for you... i had the misfortune of wiring one of my coils ( 350 GTR ) with the wires hooked opposite of the + - on the terminals....accidentally hooked the positive wire to the negative and the negative to the positive. Made for no spark at that coil. I did not feel the coil for any heat resulting, but probably would have felt something had i checked. If the connection is correct at the coils, perhaps the wiring leading away from the coils might not be correctly connected? ......just a thought on a possibilty for you to check out. bsforever
