2011 Spyder not starting - HELP?

[electricman]

My 2011 CanAm Spyder had a tender on it, but when trying to start it after about three weeks all the gauges went crazy back and forth up AND DOWN HELP BATTERY AT 13 1/2 VOLTS .

How old is that battery electricman?? And what voltage does the battery show WHILE you are actually trying to crank it over/while the gauges are going berserk??

With 13.5 volts showing, it could just be a surface charge & not an actual reflection of the battery's charge/capacity. From what you describe, it sounds a lot like the battery has at least one dead cell &/or there's a dodgy earth somewhere; or the starter/start solenoid is not in good condition so that the voltage is being sucked down waaayy too low whenever you try to start. That 'gauges going crazy' thing is a fairly good sign of low voltage to the cluster/poor battery condition...

If you don't have a multimeter to check the voltage while actually cranking as suggested above, then it might be a good idea to get the battery load tested. If the battery is anything more than about 3 years old & has been on a battery tender for most of its life, then it's probably a good idea to do that anyway! Battery tenders are good for batteries during lay-over periods; not so good for batteries long term; and if it's a trickle charger & not a battery tender/conditioner, then they're not good at all to leave connected all the time instead of simply when actually recharging a low voltage battery - leave one of those on too long/too much & you'll eventually kill the battery! Your best bet to keep your battery in good condition is to ryde the Spyder for at least an hour or more once every week or so whenever you can!

Over to you. Good Luck!

Have your Battery 'load tested'.
Most local Auto Parts Stores can do this.

Generally they do it for Free. ......

If you have a volt meter installed on your bike, watch the volts as you are cranking it. If it drops below 10v's, the battery needs to be replaced.
