When fitting my SatNav mount, I got my voltmeter and removed the seat to find a convenient ignition-switched source. I should have just gone straight into the lighting circuit,
but being lazy, I noticed that there was a connector quite close to the battery, so I tested the voltage reading from it and sure enough, 0v with no ignition and 12v with ignition on. Perfect!! So I made a joint into the wire and fitted my SatNav.
A few days later, I decided to have a full day out on the bike and connected the SatNav to its mount. With the ignition on, the
charging symbol lit up and off I went on my journey. Somewhere in the Lake District, I moved into an area I'd never visited before and kinda got lost. So I pulled over to plot a destination on the SatNav only to find out that the low-battery symbol was flashing!! I couldn't understand it because when I'd set off, it was charging.
Anyway, I set off riding again and noticed that occasionally (and very briefly) the charging symbol would reappear. It was infuriating. I pulled over to the kerb and yes, it was definately on. As I pulled away, it went off. Pull over to the kerb - it started charging again. WTF???
I then realised what was happening - the charging symbol was coming on when I was stationary with the
clutch pulled in. As soon as I moved off and released the clutch, the charging ceased. I had obviously tapped into the circuit which detects if the clutch is pulled in
What a dumbass
. Sorted now.
