i have an 08 XL1200L, when i try to start it , it clicks and loses all power like it throws a breaker. after a time it will reset, i have checked wires and ground they seem good and secure. the battery is new.
Welcome to the forum. Put a multimeter across the battery terminals and read the standing voltage. Push start button while reading the voltage. Report back with the findings.
Welcome to The Forum, as Bodeen suggests check the voltage and check back in, never assume a NEW battery to be good until you check it out fully. Up til replacing the battery was your bike starting OK?
