As the title says, I have an 88 BMW K75 that was left parked, covered for 10 days while I was on vacation. I'd ridden it multiple times in the days leading up to going away. When I got back, the battery was flat dead to the point that the time wasn't even displaying on my Acewell speedo and my smart charger wouldn't even pick up that a battery was there.
I'm fine going out and buying a new battery, but I also wanted to find out if what happened is normal. I know batteries discharge over time of not being used, but to have a battery go flat dead in 10 days - does that just speak to the battery itself finally giving up or something possibly more nefarious in my electrical?
For reference, I've done a fair amount of electrical work on the bike to install a BEP, new speedo, LEDs, and relocate the ignition by removing the power socket attached to the coil cover and running the ignition into that spot.
I've never had an issue with power draw like this before or errant power issues like fuses going, etc. so I'm hoping it's just an old battery giving up the ghost.
Thoughts?
