Car Forum / Land Rover Cars / November 2007110 Battery drain.
Now that I'm cruising around in the new toy the 110 has been parked up for longer periods. Since I've had it it's had issues with holding it's charge. The battery is new a few months back (last one was too small and similar issues), Alternator is kicking out fine so I finally got off my butt and checked the drain. With an ammeter I checked and the following drains were found on the battery. Radio 100mA Clock 6 mA Summat else yet untraced 1mA from a brown wire which runs from the battery in to the engine bay and disappears in to a harness. Everything seems to work with it disconnected . I'm assuming it's to the alternator???? Is this right for a radio to pull so much current when in standby (i.e. memory retention only). Surely if an analogue clock can run on 6ma then the radio is taking the piss a bit, It's getting right on my tits!

How long is it sat idle for? I give all of my cars a one-hour run once a week and that's been enough to keep the batteries in good condition and keep the gremlins away. > Is this right for a radio to pull so much current when in standby (i.e. > memory retention only).

It does seem a little OTT if all it's doing is keeping some memory powered to store settings, that should be in the microamps range I'd have thought, not a tenth of an amp, even at 12 volts. Those FM transmitters for things like ipod connection only take 30mA at full chat.

Are you sure your one is going to sleep with the ignition off? Ive mentioned this before, but i got one the other month for the same reason. They are well easy to use, and will test up to 20a. My heated screen draws 16A per side when its on :) http://www.maplin.co.uk/Module.aspx?ModuleNo=217879&&source=14&doy=18m11 The brown wire from the alternator goes up to the light on the dash, so i cannot see why it would take a visit to the battery box. Has it got proper terminals on it, or the crimp type? Did Nige install anything extra? I got a solar panel trickle charger from Maplin the other day - On offer for 9.99, and just plugs into the cig socket. Seems to work ok so far.

If thats the one I think it is I got one the other week to keep the generator battery topped up. It would do 50% better job of that if it didn't have a blue LED winking away at 50% duty cycle...

It's on it all the time - Its run at least once a week. The radio is headed for the bin. The clock is disconnected, I only look at it when I'm late.. if I'm late theres no point looking anyway! :-) As for the brown wire it has a proper circular connector to the bolt... looks like it's factory fit as it goes to part of the harness with three connectors, but only one is connected to this brown mystery wire. Battery is not on charge because it's snowing! :-) Lee D > Battery is not on charge because it's snowing! really? you must have your own special microclimate as its just pissing it down here! If its snowing its because i pulled the series apart and was going to put it back together today but its too soggy outside :( Mark Solesbury <marksolesbury@asearchenginethatnowdoeseverythingmail.com> uttered summat worrerz funny about: >> Now that I'm cruising around in the new toy the 110 has been parked >> up for longer periods.

I used a multimeter and pulled all the fuses to identify each offending item. Then I disconnected the radio and clock which leaves only the spooky brown wire.

I swapped the radio for one with a cd just after I got it so maybe the answer is as I suspect - shite radio/cd.
