AHA!! So, if I disconnect the negative with everything I can turn off turned off, and I get a spark does that say there is something making a circuit so something is wrong? Would a tracker still plugged in cause such a spark? Running Restoration Thread http://www.defender2.net/forum/post323197.html#323197 Self confessed mileage hunter  |

Good job on the Multi-Meter Shaggy...
It would have been my choice if they did it in Green... 
Just waiting for mine to check out the quality and functionality, if it turns out to be good value, and as well built as some of the reviews suggest, I may even consider a slightly more expensive model, in Green of course...  Rog...

Thank You Venomator
Like you it was a done deal but because it was blue Anyway had a quick go and hopefully I have found some meaningful things. Old battery after being on charge since 11:30 is showing 12.57 with the number dropping off my a tenth of a milivolt every 5 seconds (is that normal?) with the charged disconnected When I plugged it into the charger again this went to 12.78 and stayed steady. Outside in the defender new battery with everything off I can turn off (only things drawing are tracker and clock and radio) was measuring 12.64 V What does this mean and have I tested the right things?

You'd be better connecting the multimeter, set on DC amps between the negative post of the battery and the earth lead. This will indicate what the AMP draw is from the battery. If you've just got the clock and the like running then your looking for 0.5 amp max I'd say, that's around a 6watt consumption about the same as a sidelight.
I started with nothing and still have most of it left! |

don't try and hurry it , leave it on a low charge for a long time , trying to hurry it along you will get a voltage but no guts to it |

Did it but not sure I did it right because nothing much really happened
I have never used one of these before so this is what I did. Unplugged negative lead. Set dial to 2m on A with straight line above and 3 dots below Put red lead to battery - and black lead to the loose cable. nothing happened.

10A seems to be the highest setting on your dial? As Munch says, start there and see what you get, although I would go straight to the Earth connector, rather than try and use the loose lead... Rog...

And you'll probably need to plug the Black lead into the left hand socket...
EDIT - and yes, you were using the cables the conventional way round... Rog...
