Sinnis Terrain 125 problem….

[Moo3264]

I have a Sinnis Terrain 125 and recently I’ve been having some problems with it.
When the keys aren’t in, the light is still on the dash.
It now doesn’t start up, I’ve got an alarm fitted so when I’m trying to start it the alarm is going off and the engine is ticking over like it is trying to start.

I’ve took it to the garage and they replaced the battery but that’s not resolved anything but obviously with it being Christmas time the garage is now closed.
Any ideas please? Many thanks

It seems obvious that the alarm is causing a problem.

How to fix is anybody's guess.

Is it an alarm linked to an immobiliser or just an alarm? If the latter, just disconnect it and see what happens.

 

Also the term 'the engine is ticking over' means it's running, but at throttle closed / minimum revs position like you'll have it with the bike on the stand 'ticking over'. I assume you mean turning over, but not actually starting.

It’s linked to a immobiliser and yeah sorry, it’s not actually starting

Have you got a spark at the plug?

The neutral light shouldn't be on when the keys are out of the ignition. I suspect you're primary issue is a short somewhere in the wiring loom. The alarm is probably a secondary symptom. The electrics on these aren't the best. You are going to either need to get methodical with a multimeter or hand it over to someone experienced in electrics. Not all mechanics are experts with electrics so ask around.

First thing to mind is Sounds like the alarm/immobliser or a fuse.

 

After that Check connections for corrosion and loom for chafing and tight spots around the frame or connectors.

Ground ( earthing points) are bad for those bikes.

check relays and switches (little black boxes).
