Looking for some help with a tech issue (power cutting out):
All sensors have been removed. All bone stock electrics and battery, I only have the fisher fab house light installed. Bike has 3900km's on it... bike and battery was well taken care of, not ridden excessively hard. Everything worked flawless until now...
Sometimes, if I turn the ignition, it won't turn on. Sometimes I get just the speedo and no battery, sometimes everything turns on but it will hesitate and the speedo flashes....sometimes it will go but while riding it will cut out power to rear wheel, but the speedo stays on and battery % gauge goes out.
I have an X controller in the mail, the plan is to swap that and see if that solves the issue, if it doesn't, then I'll move onto the battery. Unfortunately I don't have anyone close by that wants to do a quick battery swap to help troubleshoot things...that would be super helpful..
*side question: The way it's reacting, I'm also leaning toward this being a BMS issue. I always would charge to ~ 80-90% over the past 3 years.., with full charges every now and then. If I understand correctly, the charger will perform cell balancing after it's reached 100%, but does the BMS in the battery actively seek to balance the cells also? what if it's been sitting for a long time? can it do this while outside of the bike?
My theory is that I may have a weak cell and it's causing the BMS to trip, or the BMS is just dead and that weak cell is only balanced during the 100% charge cycle. I'm not the best with electro gizmo's so I'm sure their are some experts on here that will be able to chime in on this.
Thanks!
