Thanks for all these replies - very helpful

I had thought so too, but couldn't remember, which is why I posted this. I guess Oily Hands will know as suggested earlier. I'll give him a call.

Any recomendations for a replacement K gasket? Or should I just get a normal one from a garage? Failed on seven year old S2 Elise for no apparent reason. All the coolent disappeared from the header tank, and the dip stick showed blobs of water. The RAC man told my son he didn't need a break down truck as the car could safely be driven!! - son insisted and RAC man got very

So it makes sense to have first, the highest cranking amps, second the highest amp hours, when choosing between batteries of similar size and weight, irrespective of the car?

Sorry to ask such a simple question on here, but electrics are a mystery. Presumably it is better to use the highest amperage battery - all other things being equal - as this will have more lasting power, for example when starting?

Hi Geoff, yhm.

Thanks for all these replies - they confirm my suspicion that the problem lies with the voltage regulator, but I don't know why it might have failed. Any ideas? The alternator is a separate unit as Gridgway pointed out, and I see that the regulator is an integral part, so it looks as if I need to replace the whole thing. I'll get it off today and take it apart, but it might be easier just to buy a new unit from a breakers yard. I can only find two fuses, one in the starter circuit and the other in the ignition circuit, and sadly both are intact, so I'm uncertain yet what other damage may have been caused. Any speculation? I guess I'll find out when I am able to connect another battery.

This is not strictly 7, as it happened yesterday on my Radical, but the problem is generic so I guess there will be some knowledgeable BC users who are able to give advice. All the electrics failed, and when the car rolled to a stop there was a strong smell of battery acid. Investigation showed the battery swollen at the sides by a couple of inches, and hot fluid leaking out through the stretched seams. The engine is a ZZR1100 Kawasaki, and I think the starter and alternator are the same unit. I took the battery out this morning and it still gives a voltage reading (12.7v), so there must be a blown fuse somewhere in the wiring, which i will eventually find. Question is, how could this happen? Is it likely that the alternator regulator has failed, and the battery has seriously over charged? It is a tiny battery and I had to jump start the car yesterday morning in the cold, and it had been outside all night on the trailer, when it was below freezing. Anyone any ideas?

Faced with the same issue I just took the screen off and fitted the aero screen. It passed no problem

Bent or wrecked beyond repair, or just old. Must have clean registration and be very cheap.

Thanks Mike - I have replied.
