2007 C90 after rideing it for about 45 miutes the Battery goes de

Have you checked the safety switch on your kickstand?

Battery is dead or no capacity. Check charge. A battery can read correct voltage but have no capacity. battery should be 13.8 volts fully charged approximately.

Did this just happen after storage or was it working fine then had the problem>? Needs more details and history to diagnose. How old is the battery??.

Classic failure that I have experienced twice now while riding a 2007 Suzuki C90. Both times the bike went totally dead electrically while going down the road. In both cases, I sent a fellow rider off with my battery, to buy a battery that fit. That's how I got home, with the ignition system running off of the battery alone. The old battery was the first bad actor. It shorted out internally causing the regulator rectifier to call for max amps from the stator, burning the stator up...melting windings...both times. Replace the battery with a high quality battery, and replace the stator and rectifier/regulator with top end stuff...like Ricks Motorsports. Yes it costs three times as much, but it handles three times the wattage. Don't go back with OEM parts like I did the first time. It will fail again just after the warranty expires.

Do a hydro test on the battery, replace the battery if below 1200. Check the reftact thing ... bridge rectifier ... for shorts. And of course check the alternator for output.

COuld be a bad battery or there is a loose (or corroded) connection somewhere. Check to be sure everything is tight, and clean on the battery terminals. If this happens after short trips, or after trips when your bike sat for a while, or on colder days it's probably just time for a new battery.

I think this should be a correct replacement battery for your bike -

I think you need a battery it is not holding a charge Also take voltmeter when you jump it When running put voltmeter on battery and see how many volts is charging while running It shoud be 13,50 GOOD LUCK MOPAR KENNY

Hook Voltage meter to battery while bike is running should show around 14volts around 1000RPM if not something bad in charging system

that lite is askin u if ur a hiker-test alt.system soon-probly needs new brushes...chec wiring thru out bike for cuts n corrosion-make sure batt connec is secure-

Sure take out the battery for 30-45 miutes .After replacing the battery the phone wil no longer have a lock code stored in it.
