The battery is two year old ,
But at 15/ 18,000 revs the alternator doesn't put out a lot of charge , then the run time is 15 minutes , times two , which is hardly long enough to put back what the alarm takes out over the ten to fourteen days of sitting .
Battery voltage was down to nine volts , too low for my solar panel to get going .
Had to be put on the old 240v battery charger .
Started alright this morning.
