Hi Stu from Worlds End (I know where that is!) . . . Do what Don suggests. Also, if you have a multimeter, do the following: 1 Connect up one battery terminal as normal. 2 With second terminal disconnected, set the meter to Amps and connect it between this terminal and the disconnected battery lead. The meter will now read any current flowing out of the battery. 3 Make sure EVERYTHING on the vehicle is switched off (lights, ignition, interior lights, radio...) and check the meter reading. It should be almost zero. 4 Switch meter to Milliamps (1000x more sensitive). The current flowing out of the battery should be around 50mA maximum, possibly as low as 10-20mA. Anything more than 50mA, and something somewhere is gradually flattening your battery. Usual suspects are interior light (not going out), alternator (faulty component - check the current drain in same method as above, but pull the vehicle fuse marked ALT, which fuses the "permanent live" to the alternator, and isn't cut off by the ignition switch), radio/alarm (pull fuse to check). In fact, if you have an unhelpful current drain, then pulling fuses one at a time helps to pin it down. Some neighbours of mine (petrol RAV same as yours) had the same fault last year. An idiot automotive "electrician" had replaced the 3-pin connector to the alternator, and managed to reverse two of the cables! Same result: battery flat after 2-3 days. Obviously, this couldn't happen twice!? Good luck, Chris
