Does anyone have the wiring diagram for a 300ex? I just finished rebuilding my 300ex and Im not getting spark.

i dont hav one, but i just got mine running. mine didnt have spark either... is it turning over by the push button? best bet is to cut all the tape and stuff so that u can check for breaks in wire. other than that, check the two wires down on the right side of the motor(rear brake lever)... check your grounds. check ur coil, switches, rectifier, and cdi. make sure u u get ahold of a volt tester (multimeter) and just check everything. once you follow every bare wire, u will know everything about where ur wiring goes.

do you know how many amps are coming from the pulse generator to the coil? I don't really want to fry my multimeter.
