Electric starter

[Keith Milligan]

I purchased a Pioneer Nevada 125cc. The bike is fine except it wont start on the electric starter. It has a new starter fit by the previous owner..also a new battery..where do i start to fix or find the fault with the electric start..starts fine with kick start..

It would help to know what is happening.  Is it turning over on the starter but just not firing? Or not turning over at all? 

 

It could be a weak battery or a bad contact somewhere. Or a fuse / relay. Or a fault with the starter switch. 

 

Do you have a multimeter to check connectors and current flow to the starter?

Nothing is happening when button is pressed,.its a new battery

[Keith Milligan]

Yes i have a tester...

If you hear a 'clunk' when you press the button, then the solenoid is operating and the fault will be the corrections to the starter motor.

 

If you do not here a 'clunk' then you need to put your tester (set to 20V0 across the terminals on the solenoid (the two thinner wires) and see it you get voltage when you press the button. If no, then you need to check the connectors from the battery (fuse?), to the button and the button to the solenoid.

 

Good luck.

Thank you..will try that tomorrow...many thanks

A new battery doesn't mean its fully charged, unless you've given it a charge before fitting it. 

 

You'd expect it to have sufficient charge to at least turn it over though. But what if there's a parasitic drain on the bike due to an electrical issue somewhere? Your new battery is going to lose charge without you knowing it. 

 

Fully charge the battery. Remove the earth connection.  Then put your multimeter between the negative terminal and the disconnected earth lead, set the reading check small current flow. You might get a few milliamps if you have a clock or alarm running. But anything more and there's a drain.
