Flat Battery Investigations

[notorious]

0.35A is a bit high.

I've got 0.13A total drain at battery terminals. Still too high IMHO. About half of that is stereo one in the boot (car is RNS-E upgraded), the rest is "Yellow 4", plus very minor current in "Brown 1" and in "Brown 3".

I measure at battery terminals. Lock car and wait for 3 minutes when RNS-E goes to sleep.

I'm very interested to know how your "Yellow 4" investigation will finish.

Any 3rd party electrical equipment installed?

I'd like to recommend this battery isolator switch: http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=230825055786
Very convenient to quickly connect/disconnect battery. In disconnected mode just connect tester to measure drain current.

In terms of clamp meter the one that Goran recommend will be too rough to measure mA currents. I'd go for this one: http://astore.amazon.com/m0711-20/detail/B001TCWL1E
