Hi Guys,

I'm having some electrical problems now. happened all of a sudden.

Last sunday I've taken the bike out to a Supermoto race around here in Holland.

I knew I was low on gas, damn fuel station didn't worked and other was about 6 km's away. so took that way, halfway a Sputter and left me aside of the road with no gas. till here the fuel light did worked.

When I came back to my bike after the Supermoto race was finished, there was no problem at all, rode about 70 km's to get there and did the trip very relaxed(no overwhelming gas cracking). So I thought there was enough Gas in the tank and I could make it home without refueling.

So I took off and I knew the light should come on around 80-85 km's. And it didn't. Ended the trip with a 120 km's radius rode on one tank. but all those km's from 80 to 120 km's the Fuel Reserve light did not get lighted up.

So I know it is a electrical problem BUT I don't have a clue where to look to try and resolve it.

If anyone knows what it could be, feel free to reply and help me out.

BTW.: all other functions of the Display work fine. but bike is little hard to start sometimes. during start procedure front light flickers and starter clicks at that moment. so it also could be due a bad battery. (will have to clear this one as last) since all other functions are just working fine.

It's a fairly common problem. There's a fuel level sensor attached to the fuel pump. A lot of time the wire connection comes off or the sensor goes bad. Husqvarna uses the same fuel pump assembly. Both my Ape and Husky don't work.

Is it easy to change or not?

Remove tank and drain and there are 6 8mm bolts attaching the pump to the bottom of the tank..
Slide this out and you will see the pump assembly..
Someone will be able to point you towards the correct wire
I was amazed that none of these wires were sealed or protected from the petrol tbh
Good luck

the funiest thing is that the battery charger says that the battery is fully loaded.

When my fuel low light stopped working I took the pump out and the sensor rod was actually broken in half. I can't for the life of me figure out how that happened but it did.

Quick connect fitting. Push hose on, pull orange collar towards hose pull hose and collar off. Will be under pressure, so be careful and have a rag handy.
