2006 XB12R electrical issue???
 

So i have a problem and am requesting help: the buell is dead and i cant figure out why. I turn the key and the needles rotate but the engine does not prime, i press the starter button nothing happens. I charged the battery and it seems fine. I bought new relays and swtitched them out... nothing. Is there another fuse box other then the one in the front right upper fairing that i am missing?

Dead fuel pump, maybe?

Maybe not, since you said the engine won't turn over.

Does it have any of those sensors in it that keep it from starting if the kickstand is down, bike not in neutral, clutch not pulled, etc? Maybe one of those is stuck.

I thought about that, but that wouldn't stop fuel pump from priming?? Would it?

Depends on the bike, I suppose.

Do you have a manual? Check a wiring diagram to see if something like a tip over switch would kill the fuel pump. It could be set up to stop the pump in case of an accident.

I've heard of Buells developing dead shorts in the fuel pump circuit after having wires rub the frame. Make sure the Fuel Pump Fuse is not blown. I wouldnt think that would effect your starter but I'm not familiar with how your bike is set up so it's something to look into.

When you turn on the key, does the headlight usually turn on? (Mine only turns on after the bike starts.) I was just thinking, if the light is very dim or not even on, then it could be a loose ground.

I've noticed that V-twins in particular are very picky about having a fully charged battery. My TLR is a bastard if the battery gets down and it acts similarly to what you've described.

If you're not 110% convinced that it is charged all the way, I'd be tempted to replace it and I'd bet that will sort it out for you.

My old CBR has carbs, but looking in the shop manual at the schematic for the starter system I count three fuses, six switches, one diode, and two lights that could prevent the starter motor from turning. Holy crap.

The manual goes on to say "Apply battery voltage to the starter motor directly and check the operation." I would start there and see if the starter turns. If so, then use your voltmeter to check fuses and switches.

When mine would not turn over, I found out that it was the clutch interlock switch. I sprayed the switch at the clutch lever with electric contact cleaner and it worked. And mine also needs at least 12.4 volts on the battery to crank.

Went through similar shenanigans in the Spring with my ZX-11.

I hate to point out the obvious of course...But make sure your Kill Switch is in the right position too.

Checked that lol. Its been so long since i have ridden it wouldnt of surprised me

I'm assuming that you have the bike in neutral.... I would look into a clutch switch for sure. Have you tried push starting it?

So did you come across more fuses? Or at least properly check the ones you found? I'm still leaning towards the Kill Switch circuit/Ignition Fuse. It's the most likely thing to stop the pump and starter.

Was my first thought

Good call, he is very knowledgeable on the Buells, especially the XB's.

I also second the low battery thing. On my 1125, everything worked as normal when I turned the key, but hit the starter and nothing, no click, no attempt to crank, just dead. Hook up the battery charger and it fired right up.

If the battery is really fucked, hooking it to a charger might not work. Pull the battery completely, and run jumpers to your Jeep's batt.

Or hook the charger directly to the cables, same difference.

Depends on the charger... My shitball HF doesn't source enough...

I took apart my vfr's right controls and cleaned off the kill switch contacts. A little tarnished. My starter button wasnt fully releasing so fixed that too.

To rule out the pump you can directly wire it to your battery and see if it comes on.

Yeah, mine has enough juice to crank my diesel when it's cold... it can handle the bike :lol:

Update?

Guess not...

Life hasn't been kind. Haven't had time to look at it yet?
