[rmkillerman]

high guys i have as above a kaiser 125 2007. bought it last year with a few bits needing attention electric start choke and a few other bits, BUT my main problem it the battery will not hold a charge, i replaced to the old one that was in there and the new one was spot on up until January, now before i go and buy another battery i wanna know if anyone else had the same issue and was able to resolve it? or do i buy another battery?

cheers guys rich

Measure the whole wiring w/ Multimter (the cheapest digital model is enough to this job). Regulator/ rectifier is the main "suspect". Unregulated high volts F***ed the battery.

Check if you have a parasitic draw with a multimeter.

this isnt like looking for welding sparks is it, sorry if its not but as i said im not so used to so much electrics on bikes so "parasitic draw" means little to me

[spencer2004]

A parasitic draw is something that drains the battery while the ignition is off, for example if the headlight some how stayed on that would cause a parasitic draw. You can test for a parasitic draw using the current measuring mode on a multimeter, you dissconnect the wire from the positive battery and connect them together with the 2 multimeter probes. It will tell you if any current is being drawed from the battery. There are lots of good guides on Youtube on this subject.

You can also check that your charging system is working by measuring the voltage at the battery with the engine running, I think 14.7v is the ideal voltage.

thanks for your help guess. i've resorted atm to disconnecting the battery when its parked lol, but its due for mot so i'll have it looked at
