For $16, it's worth the gamble and you might be able to confirm for others that it will or will not work
So I've been looking them up and almost all listings specify 1988 through to 1993. Some listings even mention being a replacement for both part numbers, like this one..The CDI units are different. The 1988 model TRX300 2 and 4WD used part #30410-HC4-003. The 1989 thru 1993 2 and 4WD used part #30410-HC4-770. The parts look the same and will plug into the wiring harness, but they are different even though they cost the same.
Ahh I wasn't sure. In the wiring diagram it does show a feed to the CDI split off from one of the three yellow alternator feeds. I had also read about this factor in an earlier thread, actually the same thread I quoted you from at the start of this thread. See it pasted below..Also, the regulator has no effect on spark.
Old thread but neutral safety will 100% disable spark. Fixed my fair share of non running Honda’s by bypassing that. No neutral light equals no spark.To the best of my knowledge, the neutral switch has nothing to do with whether or not you get spark.
If it's not in neutral, or if it is in reverse, then the LH lever switch has to be closed by pulling in on the lever before the engine will crank - other than that, it has no effect on spark. Also, the regulator has no effect on spark.
Besides the switch and the wiring, the ignition system consists of the stator, pulse generator, CDI box and the coil - when it comes to the wiring harness, a bad ground is the first suspect followed by connections and then broken wires.
Only if the clutch switch fails or the circuit of the clutch switch fails continuity and yes, bypassing it will eliminate the problem.Old thread but neutral safety will 100% disable spark. Fixed my fair share of non running Honda’s by bypassing that. No neutral light equals no spark.
With that description I can see why - sorry I can't help you.Currently I have cut plugs for the CDI box and Rev box (not using the Rev - safety box just have the plugs - same as the CDI - to use as connection sources....I have the switch wired for starter...
The Stator is factory plugged to the restate..
I have the Exited wire bare - the switch power from the kill switch bare - grounded Neg motor bare - Coil inlet bare - chase bare.
I have good ground from motor to chase, and another one to the neg battery...
I just can't get spark...
