Long story. At the beginning of the season my battery was dead in my 15 SX. Had it on a lithium charger all winter. Shorai sent me a new battery. Bike was fine. I sent it out for a valve adjust. Came back fine. I road it for a few days then it sat for a couple of weeks. Battery dead. Sent Shorai the battery for replacement. In the mean time I purchased a Battery Tender Lithium battery. Install it. It was fine again. New battery came in the mail. Save for back up. Rode it on & off for a week then road one of my other bikes. Came back to it today for a ride. You guessed it, dead!! All the dead batteries were beyond charging. Dead. To light for paperweights!
Went out on my Vic came back & installed the back up battery. Check the state of charge, 13.14Volts. Started the engine & it read 13.80-13.85 revving it.
Checked for a draw. Switched to amps & hooked meter it between the battery neg & the ground wire with engine off. No draw!!
I'm stumped. One battery I could understand, three, duh.
