Hi All, It's been a while since I replied on this thread but i went out and got myself a voltmeter. I charged the battery using a wall charger and measured the voltage every day for a week or so. It held steady at 12.5v for over a week. I put it back on the bike and measured the voltage again with the engine off. Still 12.5v. I started the engine, waited a short while and measured again, now it was 13.5v. So, everything was looking good. However, a week later I came to start the bike and it was flat again. Now the battery is off the bike again and only showing 10.1 volts, so something has flattened it. Can anyone tell me how I use my multimeter to test where the fault/short is? I don't know where to start. Any help gratefully received. Thanks, Adam.

Thanks man. Will go and buy myself a digital voltmeter. Cheers for the help.

Hi All, First time on here so firstly, hello! I have an XV535 that is eating batteries and I wondered if anyone can tell me what's wrong with it. I've put two new ones on now and they both just flattened within a few months. The first time it happened I assumed it was because I didn't look after it very well over winter. Since then I've put another one on and it's flattened that too. If I don't ride the thing every day then after about a month it'll need charging. I think it's getting worse too, the last battery lasted about 2 months total and now it's fried. It's also had performance problems for as long as I can remember. Several garages have looked at it and told me they can't find anything wrong, but a mate told me it might be a dodgy regulator/rectifier causing it to flatten the batteries. Can anyone confirm is this is likely? Is there a way I can easily test the regulator/rectifier to see if it's faulty before I buy a new one? Thanks in advance for any advice, Adam.
