First problem.......

[JonaStorm]

Went to start the bike today and just a buzzing from the starter solenoid. Noticed the battery had been leaking slightly so jumped the bike off another bike battery and it started very easily.
Put a multimeter on the battery and noticed it's charging at 18 volt at idle!!!!
As I rode it 130 miles home after picking up it's obviously buggered the battery and obviously the reg/rec is stuffed, which is the original old type i.e non-finned.
My question after this long ramble is, is it likely to have done other damage as the tachometer was intermittent when it did start?
Not a great start to life with my new toy
Thanks

It shouldn't have done damage to anything else a 12v system will only use 12v. If you swap the battery and reg/rec you should find it all goes back to normal

Put a new R/R on and a new battery and test it all with a multimeter juts to verify everything is allright. There is a slight chance that a voltage spike has damaged the ECU or something, you wont know untill you fix the fault and start the bike. Fingers crossed. The tach playing up is a sign of the R/R being faulty, nothing unusual there.

Well I now have a new Yuasa battery and later Reg/Rec to fit tonight so wish me luck.
No wonder the charging was all over the place, when I took the original Reg/Rec off there was a 10 mm split in it with some molten solder poking out of the slit!!
Please keep your fingers crossed that it has not damaged anything else.

Please verify that the charging system is working as it should once you have these fitted. Yuasa batteries are the best and not cheap. It would be a shame if the new R/R was overcharging (it happens from time to time) and kills the new battery.

Fingers crossed.

I'm pleased to report that the new battery and RR are fine, charging at idle is stable at about 13.6 volts so all good thanks.
