Battery going dead.

Mike40M · May 17, 2021

On the BSA unit single I made new wiring on last year, I fitted a 3 way ignition switch ( + an unused starter motor position).
Pos 1: Ignition on, battery connected to charging system.
Pos 2: Ignition off, battery disconnected. Key removable.
Pos 3: Ignition on, battery disconnected. Emergency starting thanks to the MC2 capacitor.
Works well, only had to recharge battery once during winter hibernate. Never need to take out fuse or disconnect battery.
Will make something similar on the 650SS project.

The TexasSlick switch suggestion is good and easy to do, especially if the switch is hidden. Limiting unauthorised starting of the bike.

My last post here was Sep 2020. I still have that smart charger connected to my Norton 2008 AGM battery I got from Clubman. It still starts the bike (Pazon) and will hold a charge as long as the battery is being charged. I should let it go for a few days and see what the battery goes down to. I have the same type chargers on my Miata, that (replacemtnt AGM) battery must be 8-10 years old now and they typically last 2-3 years. The original Miata Panasonic AGM lasted 12 years (2000 vintage) I also keep it on my Simplicity mower and the JD 2020 with double batteries for the diesel starter full time. They do seem to work pretty good, the smart chargers, that is. I've been very happy with them. Used to be I was buying batteries every other year. The OEM battery in my 03 Dakota lasted 17 years, but I hardly used it in that time period. It's still on the 2nd LA battery from Wallyworld. I never used the chargers on the Dakota.

I put an AGM battery on my Mk3 six years ago, it's inactive during the winter months and I'll admit I only use the electric foot out of curiosity, but it wasn't until three/four months ago that I actually bought a charger for it and gave it it's first ever boost...
