Put my 07 c50 to sleep last fall. Beautiful weekend so I decided to wake her up from her heated winter sleep. Air up the tires, checked for leaks, metered the battery, turned the key on, the fuel pump spins up, gauges do their thing, pulled in the clutch, hit the start button, slight click.... All lights and gauges go out. Nothing happening. I checked all the cables, ditto on multiple attempts.
A few times I left the key on and a minute or so later the fuel pump spins on, the lights return. I attempted to start with same results. most times the lights don't return. I'm thinking a bad/imtermittant solenoid which sits next to the battery... Any thoughts out there???
had that happen once...turns out I had disconnected the battery and when I reconnected It, I hadn't tightened the bolts back on tight enough...thought I had but upon further inspection and retightening, that turned out to be the issue.
then again there was the issue I had last year...same scenario...sometimes starts sometimes not...bring it into service where guy tells me unless the situation reoocurs theres pretty much little they will really be able to do...tells me to leave it, makes a few initial checks on obvious possibilities and spends the day constantly starting it w/o any problems...does tell me he initially sprayed some electrical contact cleaner in starter so maybe that was the issue. Tells me to come pick up the bike...go to leave and what do you know...turn the key, hit the button...nada. Was quite relieved it happened there. Guy was somewhat embarrassed but yet glad it happened there so they could now locate the problem Turned out to be a bad starter.
Sounds like a bad battery or bad connection. If it's fully charged put a meter on it while your hitting the start button, I bet it's dropping out below 10 volts when you hit the start button. Bad cell possibly - how old is the battery?
Put the meter on the battery and press the starter button. If you are at or below 12.5 V then your battery needs to be charged.
Crank it with the meter connected and you will see a voltage drop. Should not drop below about 11.5 V.
If you don't have a trickle battery charger and you store your bike it would be a wise investment so you won't be buying a battery every spring.
Good luck getting it going!
as soon as I touch the start button all the lights and gauges go dead. I do run a trickle charger all winter. The battery reads 13.5 volts but I have not put the meter on it when I hit the switch. After I hit the switch it will remain dead for a random unspecified time. I am leaning towards a bad relay... will test out tonight and repost.
Weeelllll.... metered the battery and turned the ignition on. Hit the starter button the voltage dropped to zero. Three year old die hard had died. new battery good as gold. Thanks for whoever nailed it.
Good you got it going. Batteries aren't made like they used to be. 2-3 years seems to be the average for car and bike batteries. Only 3 battery manufacturers so no matter what the brand it comes from one of them.
