An Electrical Challenge

Hi folks,

I've just picked up a second hand 2012 Pulse Adrenaline 125.

All is grand, except the headlights which do not seem to be working.

The following things do work:

- All indicators
- Brake lights when operated with front lever and rear pedal
- Main beam 'flasher'.

The following things do not work:

- Dipped headlight
- Main beam light when used from thumb switch
- Tail light.

I have replaced the dipped headlight bulb as I initially thought it was this at fault - but no joy.

It seems odd that the tail light does not work in addition to the dipped headlight and main beam, but the beam does work when operated with the 'flasher' switch.

Is anyone aware whether there is a separate circuit or fuse that these three lights run on, and that there could potentially be a problem with?

Happy to provide photos or further descriptions if it aids diagnosis.

All the best,
AJE

Dear Aje,

Welcome to MCM, and good luck with the new Adrenaline. Please let us know whether you get the answers you need from the service manuals Humanbeing has offered.

Looking forward to seeing pix of your bike and where you ride it!

might seem obvious and I don't mean to sound patronising, but checked any headlight fuse?

if it is not the fuse: I had an almost identical problem last week on a friend's bike.
The small front running lights, the tail light and the license plate light run on a seperate circuit, and were all out.

It happened to be a slightly corroded contact inside the key-contact.
Lots of contact spray and moving the key left to right finally fixed it.

Must say that on a Benelli, the headlights only come on after starting the engine.
But the above mentioned running lights / tail light come already on when you turn the key, getting the power from there.

Thanks folks, apologies for the late reply. I found a loose connection in the bundle of wires near the headlight. All seems to be working now.

Cheers for the replies.
