Looking for a sticking-plaster for the eternal battery drain

............ If I test the battery for current draw using a multimeter what sort of figures should I find?

You should get approx 12 volts + with everything off and then starting should not drop below 10 volts and then something in excess of 14 volts with the engine running, i.e. alternator charging the battery.
