2006 XB12R electrical issue???

I've noticed that V-twins in particular are very picky about having a fully charged battery. My TLR is a bastard if the battery gets down and it acts similarly to what you've described.

If you're not 110% convinced that it is charged all the way, I'd be tempted to replace it and I'd bet that will sort it out for you.

My old CBR has carbs, but looking in the shop manual at the schematic for the starter system I count three fuses, six switches, one diode, and two lights that could prevent the starter motor from turning. Holy crap.

The manual goes on to say "Apply battery voltage to the starter motor directly and check the operation." I would start there and see if the starter turns. If so, then use your voltmeter to check fuses and switches.

When mine would not turn over, I found out that it was the clutch interlock switch. I sprayed the switch at the clutch lever with electric contact cleaner and it worked. And mine also needs at least 12.4 volts on the battery to crank.
