How old is the battery? What voltage do you read when you hit the starter?

My Kaw Barn - 2004 KLR, 2006 Concours (sold), 1997 Bayou 400.

"It's a friggen motorcycle, it's not supposed to be comfortable, quiet or safe. The wind noise is supposed to hurt your ears, the seat should be hard and riding it should make you shit your pants every now and then. "

Sometimes a battery will show adequate voltage, but a cell may break down under heavy current load (e.g., in starting).

Quck-and-dirty trouble-shooting check: Jump a known hot battery to yours and try it. If the bike starts easily with the jumped battery, chances are your on-board battery is deficient.

Folks will warn, if you use an automobile battery as a "donor," don't leave the automobile engine running; excess power from the car's alternator could fry your voltage regulator/rectifier. At least, that's what the big boys on the playground say!

Still won't start? Check connections, notably battery ground, starter relay, etc.

doggie12,
I'm going to strongly suggest your battery is TOO Low of voltage.
A 'good' Lead-Acid, recently charged battery should be about 12.6 volts, one hour after re-charging to 14.5 Volts.
A sealed for life AGM battery should hold 12.8 volts.

The bigger 'key' here is "when you hear the 'click', the lights mostly go out".
Connect your volt meter to the battery. Push and HOLD the starter Button.
Read the volt meter, anything less than 10.5 volts, the battery is weak or Bad.

Modify at "YOUR OWN RISK"!

Still riding my 1987 KL650-A1. 85,000+ miles & counting

Everyone has given good advice so far. But that won't prevent me from piping in.

The third fuse is behind the radiator overflow bottle. It is for only the radiator fan, so not a concern yet. The tank is off now, but if you ever need to check it while on the road you may be able to pop the triangluar screen out of the shroud on the right front of the gas tank and pull the fuse holder out to check.

Agree your battery is low. Either charge it and try again or jump. Theres nothing to fear about jumping except getting any sort of clips onto the terminals hidden down in the steel frame. No fun shorting.

Your battery MAY be low because it is too old and has lost capacity. If it sits for long periods while partially discharged then the lead sulfite crystals grow and prevent that sulphur from going back into solution (sulphuric acid) and reduce the area of lead available for the sulphuric acid that IS there. Double whammy is like your battery getting smaller.

But this time of year it's common to simply need a charge.

Ok,thanks for the tip,Ill try that,,any ideas how i can hold the 2 Volt meter prongs on the batt,,while pressing the start button? I may have to do it "chop stick" holding style,,a unseen benifit from all the oriental food places Ive eaten at,,lol. But Ill try that and see what happens,,do you think that 33,000+ on the clock,,that this may be a expected event with this many miles on it? I dont know,,Ive never had this happen,,the bikes been a solid reliable steed till now. Thanks again!

Wow,,didnt know thats what happens to batterys when dormant,,Ive stored the batt indoors thru the winter,and charged it before I installed it this time,,but electrics/batterys sometimes do strange things. I did try a "jump " batt on it today,,and it still did the same thing. I hope somehow I didnt fry the starter/relay/selenoid ect,,because the 10 amp fuse was blown,,I replaced that,,and it still did the same thing,,so?? Thanks for the info,,happy riding!

Kinda like Del Griffith said in Planes Trains And Automobiles, "Five bucks and my left nut says your battery is bad." If you have no idea how old it is, it's time to buy a new one.
