My buddy has a 99 500,Last weekend we went for a ride.We rode most of the day when we stoped for a brake.when he went to start his machine the battery was dead,I did notice his headlight was on all day which shouldnt make any difference.I just got done checking the voltage on the battery its about 12.19 volts with the light on ,when I shut off the light it goes to 12.45 volts.does anybody now what it should be,or what to check for .Any help would be nice

 

Clean all the conections on the battry and relay.That may help.
