Question about 2008 Triumph America

1 Answer

Hi, I just brought a 2008 Triumph America, I've taken it on a few short runs, no problem. Yesterday I took it out did 45 miles to work stopped, went out got some lunch couple miles, great no problems. went out later to view a job 10 miles away, still no problem, everythings great. Go to start the bike again, nothing! ignition lights are on, clutch lever in, switch on handle bar on, push starter button, nothing, its not the battery (its new anyway), there's no power going to the solinoid? The bike will start if I short circuit the main terminals (battery/starter motor) at the soliniod, Help please.

    Hi Tombones49
    I took your advise and checked the fuses again, they all looked ok, no sign of any blown fuses, but I did a continuity test on them and found one had blown, I also checked all the safety componants in the circuit, no sign of any reason why it had blown, but it seemed to do the trick.
    many thanks for help.
    regards, John

    Hi, I'm back again, this time everything on the starting side is fine, but it tries to start then cuts out, its as if theres a fuel starvation problem, it runs for a few seconds then stops, with the occasional back fire, theres a strong smel of petrol, again I'm at a complete loss.

The side stand kill switch may be out of position, Starter button wire has come disconnected somewhere along the way? Is there power from the button to the solenoid when the button is pressed. If so, get a new solenoid. If not, trace the wire back to the button and find where it has come disconnected.

    Thanks Guru,
    I had already checked if there was power to the soleniod relay when starter button was depressed, there's no supply. I can start the engine by shorting out the soleniod. I know that the side stand, neutral, clutch

    Possible problem sources have to be mentioned; switches and dead wires. You stated " there's no power going to the solinoid? ". I had no way to know you checked it and found it dead. So, as mentioned before, trace the wire back to the button and find where it has come disconnected. Is there power prior to the button? If not, trace the wires on that side of the switch. Bad button? Chances are you have already sorted out the problem by now. You obviously have repair skills.

    Thanks tombones49
    I checked all the switches by running the bike and going through safety proceedures, i.e. putting the side stand down whilst in gear etc. I've done a continuity check on the starter button, still no joy.
    EM system now working again, but starting system still at fault?
    regards, John

    Have you checked the fuse box yet? Obvious but sometimes forgotten. Heck, I failed to think of it until now. Any chance you can get your hands on a schematic? Trace the hot side of the button back to source. If your dealer can hookup a code reader it may detect the problem.

    I would start by draining the carbs. Condensation in the gas tank can make it's way into the carb float bowls. Bikes don't run well with water as fuel. I would also install a fresh set of spark plugs. Carbon on the plugs may be robbing part of the spark. I would suggest the the opposite of fuel starvation. The engine may be getting flooded due to twisting the throttle too often while starting. Another possibility is the throttle position sensors got out of whack due to the same thing that caused the fuse to blow. I doubt it but stranger things have happened. The Keihin carbs with Throttle Position Sensors, ( yours ), are not ones I have worked on. If my other suggestions don't do the trick I would need to send you to the dealers mechanic. Again, I doubt the TPS are out of whack.
