Bike sparky help needed.

[nzspokes]

My bike wont produce spark. Ive replaced coil and CDI. But just found im only getting under a volt at the CDI and coil. Have checked all the connections.

What next?

Doing my head in......

Just want to ride.

Could the rectifier/reg not be giving enough voltage to the ignition circut?

Corroded fuse holder?

You could try sticking a wire straight from the battery to the coil + and see if she goes? With the ignition on that should also power up the CDI, and tell you if it's just a wiring fault somewhere.

Not a bad idea. May try it soon. Real head scratcher for me. Normally I can fix stuff.

Fuse holder is fine. Checked most of it out. But cant find an earth of the loom. Only the battery one.

Another symptom. Not worked on it for 2 hours. Try to start it and it runs for a second then shuts down. Wont re-start.

Have recommended this excellent thread to many people, in fact it's how I found this site in the first place :-)


Try step 3 - it will tell you if you have a charging system fault

The idea of sticking a wire from battery to coil will just fry your coil, the coil needs a rapidly switched current to work, it won't do anything with DC from the battery.

Won't restart as in it cranks over at a good speed but no bursting into life?

Correct. No spark.

Ive seen that before. And for it to work I need the bike to run. Bike no go.

Should my stator have oil in it?

[nzspokes]

Using the charging system test my stator is within range between the yellow wires. But on the test to earth I get no continuity. I presume as I have it out of the bike for the earth I just put the negative to the centre that mounts to the engine.

Guess then my stator is toast?

[ducatilover]

Your stator should not earth out. If it's earthing out, fix it. You should have under 1 ohm resistance between any two stator wires.
I'm assuming it's a three wire stator?

[ducatilover]

Yes, it's a hot bath type.

[neels]

Most bikes have an AC generator, which is then fed to a rectifier/regulator to turn it into DC, there shouldn't be continuity to earth (or it's mounting if it's out of the bike).

[bogan]

Under a volt at the coil and CDI seems very low. If it is still giving good voltage at the battery I think you have a wiring fault somewhere, try some voltage checks from the CDI + to batt +, and CDI - to batt -. The other option would be that the CDI has a fault and is pulling enough current through to drop the voltage, but a fuse should blow well before you drop that many volts across the loom.
