Have a read through this fault finding guide (so simple even i can follow it) HTH

Ps nice to have you back

Thanks guys.

I received my new battery and just prepped it.

The acid kept stalling while emptying into the battery so I put a needle into the top of the acid bottle and whoosh, problem solved haha. Room stinks of egg now though.

Capped the battery and put a meter on it, already pushing out 12.5v. I can still hear the acid fizzing away so ill test again in the morning.

Hopefully will get time to install into bike and report back this weekend

Charge it fully first, or at least ride it long enough to fully charge it the first ride. Batteries tend to have memories, and you don't want your new one to think half charged is actually fully charged.

I'll stick it on charge overnight then - but if the charger see's 12.5v coming from the battery, I'm sure it will just trickle to maintain?

12.7 is fully charged,and yes it should be charged up on a proper charger before use if you want to get the best life and performance out of it.Many people dont bother,and it will work fine but possibly will expire sooner than otherwise.

13.2 volts fully charged good battery.
To get the best out of it ues a bike speck charger .

Ok, results are in. Doesnt look good.

Battery off bike - 13.4v
Idle 14.6-8v
Lights on, Idle - 13.4v
5k RPM, Lights Off - 9v
5k RPM, Lights On - 9v

What do we make of these findings....

Check the regulator and conections

Is that measured across the battery? A true 9V would mean either completely flat, or a really heavy discharge. If the latter, it would flatten the battery in no time, minutes rather than hours. I'm wondering if you have a bad connection, maybe vibrating when the engine's revved and giving a false reading. I mean even if it wasn't charging at all you shouldn't see 9V.

The link by geodude says to rev bike to 2,500 rpm for first voltage checks. I would of thought 'idle' was slower than that?
