This made me think of a few weeks back when I reset the Toyota by disconnecting/reconnecting its battery and there was a whole shed load of sparks because I'd forgotten to turn the lights off first. Oh dear.Unskilled meddling sin©e 2007

Re: Having a few flat battery problems!
Hope you had that voltage spike gizmo attached Steve!
There must be smaller such devices built into the ecu and bsi but who knows if they are and if they work!
I might have had second thoughts on buying the 406 if I had read this forum first.
To get demist and heating I'm presently running with the blower motor control unit bypassed (switched and fused) while I wait for another bsi...

Pffft, I'm not 'cos I don't give a toss about the car.
What's this stuff about the control box being bypassed while you wait for a BSI? Is there much you're not telling us

If you know what comes down the control wires from BSI to the MBVC unit I'd be delighted to hear?steve_earwig wrote:Is there much you're not telling us
If not wait till I get the replacement BSI.. re-program and fit another EEPROM and if I crack it you'll be the first to know!
Re: Having a few flat battery problems!
Malc is spot on with the figures. It may seem obvious but if the cigarette lighter is jamming when left in this can result in a fairly rapid battery drain as when leaving telephones on charge etc. Note the fuse for the lighter can be enabled to stay on when ignition is off. ( to disable find the fuse and turn it around)
Just to add to the comments, Following the normal battery disconnect procedure just connect an ammeter between the positive lead and note any current passing through - there is always a tiny amount because the system monitoring and clock take some as any alarm function does too. But this should not flatten a battery within a week of non use. A reading of 1-2 amps in winter months may do, so you would need to do some isolating. There are many current CT clamps that can be put on the positive without disconnection of the lead but some may not be sensitive enough to read all current so beware.
