Triumph Daytona 600 (2005) **Battery charge issue*

[Minty]

Hi y'all,
Friend has purchased a the above and is perma flat battery. Told him to get his multimeter out and test the voltage across the battery terminals with the engine off and then idling.

He is claiming at idle it is 12.7v and engine off is 14.4v.

Surely it would normally be the other way round??

Thoughts?

Much love,

Confused Mintah.

Nah...........that don't sound right at all. You measure it at tickover and when you rev the bike to about 4000 RPM. He needs to make sure the voltage doesn't shoot up too much at high revs, a sure sign the rec/rec is kaput. 13.5V to 14.5V is good.He can also remove the battery, charge it and them measure the volts at 30 min intervals to see how well it holds a charge. It shouldn't drop below 12.6V IIRC.
There are loads of posts about reg/rec checks on here, try a search.
Good little chart here:-
