CBF 1000 Charging/Battery Advice Req (CBF Forum crap)

[Frosties]

Same as the some of the Fireblades.  :eek

Tested one of them last year and was measuring 2v AC at idle. :rolleyes

Let me know how you get on

Same engine as the blade but detuned.

... I'm just wondering if a poor battery can show sufficient voltage but have insufficient amps available??

Yes, a  battery that's developed a high impedance can give a good voltage reading when no current is being drawn.
With the engine off and Optimate disconnected give it a decent load (turn on the headlights) and check what the voltage on the terminals is then. If it stays above 12.4V for 5 minutes then it's probably healthy… in which case the charging circuit is probably OK too.

If the battery is good it sounds more like a localised problem with the wiring for the spots and hot grips if those are the only things showing symptoms of low voltage.
Check for corroded/loose connectors (3 month old install with weatherproof industrial connections) and insulation that looks as if it's got hot. Don't forget the return side of the circuit too: you might have a decent 12.7v supplied to the grips and spots, but the earthy side might be floating at 6v.

Another good shout. Will check tomorrow  :thumbup
