hey everyone i got a 88 cane a while back that wasnt running i have yet to get it to start and by the title im sure you all figured why no spark i have tried a lot of things to no success i have checked the run switch the spark unit (even replaced it) coils regulator but cant figure it out

so please if anyone can give me some ideas on what to try doesnt matter how small or simple it would be greatly appreciated

how old is the battery??

yeah, the battery is pretty important to a sport bike, as unlike a car, which can run off its alternator at lower rpm's, a bike can't. it needs at least 3500 rpm to start producing power for the ignition system, so a weak battery can hold you back. Also, check to make sure your alternator/generator windings are good.

the battery is brand new and has a full charge

and fireblade what it the alternator/generator windings???

I mispoke. Its not so much the windings, but the leads coming from the alternator up to the regulator, and from there to the battery and ecu. check the plugs under the seat, see if its fried. A common problem with motorcycles in general is the regulator, it can cause all sorts of problems, from overcharging, and consequently melting the plug located beneath the seat, possibly causing a short, or a complete break in the electrical system...thus getting no spark, but still able to "start" the bike.

Since the battery is new, check all your cable connections, a usual suspect is the ground cable where it connects to the frame, many times this can become loose, or become corroded, and lose conductivity. with only partial conductivity, the bike may turn over, but not start, etc. Electrical problems are tough to track down, I'm a big fan with starting with the simple stuff and moving on from there.

The windings on most bikes produce something like 80 volts at 3-4000 rpms, this is knocked down to 13.6-14.4 volts via the regulator. This knockdown causes alot of heat at the regulator, which is why they go bad if they aren't properly ventilated. (honda's stock regulators are the weak point it seems in their electrical systems, I've had to replace one on just about every honda I've owned, small price to pay for the ride and power they provide ).

i do have a connector comming from the alternator that is kinda fried looks like it somehow got really hot probably was to close to the motor

i have another replacement part that has that plug in it but that piece i no is bad so now im wondering is it safe to cut that plug in and use some connectors and wire the new plug in or should i just save up the money and get a new one

You can use connectors, but be sure that your wiring is correct! If your wrong, it could do more damage. Possibly fry the ecu. With the description your giving, I'm starting to wonder if the ECU is bad...have you checked the coils for spark? You can do this by pulling the spark plugs and turning the bike over. You might check any safeties as well, the kill switch, if it has a kickstand safety switch, or neutral safety switch, both of those can kill the coils, and not allow the bike to get the spark to run. Electrical problems on bikes are not easy to track down, good luck.

the ECU was my first guess and i have actually gotter a second one that was good but it still doesnt spark

it doesnt have a kickstand switch the nuetral switch im pretty sure is good i can only turn the bike over if i have the clutch in or it is in nuetral

and when your saying to check the coils are you meaning to pull the spark plugs out and gound them and visually check for spark??

if so that is how i have been checking for spark all along

yeah, that was what I was suggesting. Seems to me your doing everything the way I would do it, and still not getting spark, do you have access to an ohm meter? if so, you can check the continuity of the spark plug wires (if you haven't already) Check the leads to the coils and make sure they are getting power, check the voltage output from the regulator with the key turned on, I wanna say, it should read something like 4 volts when checked to ground..not sure about that one tho. There are three leads that go from the alternator to the regulator, and then those same three leads leave the regulator to go back to the ecu, and from there to the coils. I'd swap the ecu's if you have an extra, but to be honest, I'm at a loss. The only thing that makes sense to me now is that the ground cable from the battery to the frame sounds like its not making good contact, and that would definitely not allow a spark to be created because there wouldn't be a completed circuit. Bike electrical problems can make you pull your hair out, and bud, I'm right there with ya. definitely have a break somewhere in the system, and I'm betting its on the ground side, only thing you can do is to start checking continuity for any suspect wires, starting with the battery and working outward on the system. Good luck man, its gotta be there somewhere.

the only ground wire i was able to find on the bike was locater on the right side of the bike and was connected underneath the collant overflow tank and i have made sure that its connected properly i dont remember what all the connections read but when i first got the bike i went thru it with a multi meter and everything checked out good

im just about ready to kick this thing over and get a different one haha but thats kinda hard when your 19 and unemployed
