Starter wiring, and ignition wire question By johnnybravo (Read 1,080 times)

I have a Jonway 150cc scooter. I just replaced the starter and the starter relay yet the scooter doesn't make a sound when I try to start it. I tested the starter button and it checks out. The relay isn't getting power from the button. Where does the starter button get it's power from?

Also the brown wire on the ignition wire cluster is registering about 80v DC or 145v ac. What does this wire do?

The button gets its power from the ignition switch

Ok. But what about the ignition wire? There's 4 wires. A ground, a constant hot to the battery, one that's a hot switched and the 4th is brown with excessive volts.

Colors are
Red. Battery+
Green. Ground
Black. Ign +
Brown. ?

The red and black wires have 12v +- coming out of them.

I'm lost on this.

What's excessive? One is the actual feed to the switch that's the one coming from the battery,the switched hot is the feed to the coil lights ,,ground obvious ,,the other is the feed to the cdi so you have an ac ignition ,,there may be something wrong with the starter solenoid (relay) wire,,,it may be broken internally and you can't see it by looking at it,,,check that wire for continuity and I'd also look at the termination plugs,,,sometimes they look just fine but are not completely seated

As a side note check to see if the frame ground to engine wire is good and the termination to the frame is clean and free of corrosion and is tight,,,I think you have a ground problem

Excessive voltage, I'm getting 80vdc or 150vac from the brown wire.

I'll recheck the grounds and the wires. I think you are on to something there. Once I check them out, I'll post up the results.

I just haven't had voltages this high on anything scooter related.

Thank you for your help with this, I really appreciate it.
