Battery Always Flat Need Help Identifying Problem

[Gameboy]

Hey guys, I have my sisters R33 GTS-T here and the damn battery is always flat in the morning. I thought it might be a buggered battery so I installed the one from my Z and that ended up going flat in just one night too.

I jumped the car and tested the voltage across the terminals and it was only 13V and when revving the car it actually droppe to 12.8V. OK, dead alt. Ill get another one but it doesnt explain why its making a freshly charged battery dead over night

I checked how much current its pulling when the car is off and its 170mA. Would that be enough to drain a bettery over night?

could possibly be the light in the boot staying on

...which means that you put your sister in the boot & shut it !!!

Then when you've kissed and made-up...

it can often be the security system draining the power away.

Sounds like a process of elimination = NEXT PLS?

Nah its not the the light its previously been removed for what ever reason. I cant see any lights. Ill keep prodding around untill I can find something. I think im going to have to take it to the auto leccy to suss it out but they charge an arm and a leg

Measure the current draw through each fuse. That will at least narrow it down a bit.

I think ill do that ey. I tested the current draw at the battery and it said 170mA but I could have had it on the wrong settings and it was 1.7A lol
