Lifan 125-3a electric start and fuel gauge dont work
hi ive recently got a lifan 125-3a as my 1st bike its got two slight problems the electric start doesnt work at all the green light dims when i press the start button but nothing happens although it kicks fine also the fuel gauge doesnt work at all either, are there any common faults that would cause these problems or do i need to get my meter out and check all the wiring??
thanks in advance for your help |

It may be new, but not fully charged. I would give a good charge and then see what you have.

It may be. What you can do is jump the two large terminals on the solenoid. If the engines turns over that is likely the problem.
Also make sure that the connections are good. Too small of ground(earth) wires are common. Adding a second or replacing with a heavier wire often helps.

I would replace that solenoid with a new one then.
The guage is likely the sending unit in the tank.

The pilot jet in your carburetor might be too small. Have you tried increasing the idle speed?

and now only the right indicator works guessing this is down to chinese build quality :? id did get a bit wet outside work yesterday which is when it started and randomly left indicator came on when riding home today after cancelling it it wouldnt come on again, are there any fuses on these things or just a mass of bad connections and relays
was just a loose connection sorted now |
