Electrics Fuse Drawing A Current

[nthside_skyline]

Hey Everyone

My S1 R33 has been running batteries flat in a few days, I would charge it up and it would be fine for three days then nothing, the battery would be dead. I figured it must be drawing current somewhere.

I bought a diagnostic tool that plugs into fuse slots to tell you whats drawing current.

After systematically testing every fuse slot, I found that the fuse that was drawing a 0.49A current was the 7th fuse up on the left hand side that says BATT in a big white block. On other printouts from the site it is for the Electrics.

Does anyone know what exactly it powers and what I may need to start looking at to stop this issue?

Any help would be appreciated guys this is doing my head in.

Cheers in advance

Mate I can't help to much, but as a sparky by trade, I can tell you a fuse it self doesn't draw any current, there has to be a load drawing current. Maybe try a isolation switch on the battery

I think that circuit is what keeps things like the clock and radio supplied with power to maintain memory, etc.

0.49A is not a big current, and shouldn't "kill" a battery in 3 days.

What is possibly killing the battery is that it is being overcharged (an alternator regulator problem). You can check by measuring volts across the battery terminals while the engine is idling and when it is at around 2k revs. Anything above about 14V is not good.
