Thread: Electrical Leak?

Just did my MY12 Defender and it was pulling 0.16A. Flew to Tamworth early Monday morning and came back yesterday night so it sat at the airport for 4 days and no problems starting. Didn't take note of the voltage when I started but the Ultragauge normally sits at about 14.25 -14.40 volts. Hope that gives you some reference numbers.

Volts are largely irrelevant, a battery showing 12.5v can still be knackered if its got no amps, 4 days on a new battery isn't really a good indication, mine will start after 2 weeks no problem on its original battery (04 TD5)

An ultra guage type tool will report the voltage while the engine is running, therefore the 14 odd volts the alt pumps out. Not a good indication of battery volts, and as stated, cranking capacity

I have narrowed it down thanks NedFlanders,
using the technique suggested. Amp meter in line with all fuses was drawing 0.15, then when i removed the interior light fuse it dropped to 0.07.
then i was stumped so started at the starter motor ( is that the first point the battery goes to? ) so then went right back to the battery with extra leads attached to the starter battery. i have a jumper lead hardwired in to an Anderson plug in the back seat for easy jump starting and this lead was drawing 0.04/5 . it has a light that says if the battery is charged and connected etc but i didn't think it would draw so much.
and now have it down to 0.02 if both those points are unplugged, but i'm unsure how to get them sorted . any tips?
thanks Jake

Get a better quality radio that doesn't drag the battery down, or turn it off altogether.

If you removed the interior light fuse it dropped to 0.07 that's acceptable, a decent battery should last on that. Does the interior light switch fuse power anything else?? Some fuses power a number of circuits without you knowing? If it doesn't them look at door switches etc, some alarms also look for volt drop when a door is opened and the light comes on. First checks we used to do was glovebox light and boot light.
