I have a 2026 Harley Davidson Softail Slim S, the battery went bad 2 weeks after I got it, I replaced the battery and everything seemed fine, then I noticed that If I did not ride or turn on my bike the battery would lose its charge. I did not ride for one day and the bike did not turn on, tested the battery and it was at 20% I put it on a charger, got it up to 50 % and got the bike to start. Kept the charger on and saw that the battery charged right up to a 100% I am wondering what could be causing this? A bad voltage regulator maybe?
I have an 08 Electra Glide Ultra Classic and the voltage dropped down while riding and the headlights dimmed. I revved the bike a few times and it came back up and brightened the headlights. No issues starting the bike, tho. What could cause this?
I have a 02 Harley Buell Blast 500 and I hooked up battery backwards and my wires smoked up white. I quickly switched battery around and connected correctly and again all my wires went up in again in white smoke so I unhooked battery and put on trickle charge. Is my electrical system going to be okay.
