Have a starting issue on my '02 FLSTI heritage with a 2 year old HD AGM battery..Battery has been kept on a trickle charger since new.
Bike fired up as normal today, road about 2 hours, stopped for 30 minutes.......Turned ignition on, set switch to on, hit the start switch and had one clunk.......all lights go out........sit for 2-3 minutes, exact same thing happens...one clunk/lights out no juice........If I leave the ignition on the lights will come back on in 2-3 minutes and are bright as normal..........hit start, clunk, lights out the the process remains the same.
Did a jump start with portable rechargeable starter, bike will fire up, but goes dead after the clamps are removed..........Guessing a dead battery, not 100% sure.........will appreciate input..Thx..Ronnie
