Battery keeps dying

[Jamieg285]

If you have a multi meter...
Set it to read Amps.  Disconnect positive lead from battery. Connect multi meter - one lead to the battery and one to the positive lead you just disconnected. With the ignition switch off the meter should read zero.  A reading of 0.1 amps will drain a bike battery within two days.
If you get a reading above zero try disconnecting the voltage regulator/rectifier. If the amps go to zero you have found your problem. Try disconnecting other things if this doesn't work.

You should always disconnect the earth lead rather than the positive.
