240sx Electrical Issues!!!

[a30mayne]

I have a brand new battery on my car and it keeps on dying over night. I tested the battery and it's at 12 volts, gave it a jump and tested it again with the alternator running, it was at 14 volts. I know it is not my alternator I'm thinking it may be a ground or something. Also the cluster lights on the left side of my cluster do not work when it is in the ON position. Just looking for some answer and suggestions. Anyone have a similar problem like this?

Sounds like you may have a short (somewhere)
I would check your fuses and inspect any recent wiring projects like new stereo/speakers etc.

I found out why the lights on my cluster did not light up and that was because I left the ECU in diagnosis mode, but as far as the battery dieing I though since I left the ECU in the on position that was the sole reason but while I was changing out my cluster lights to LEDs the battery died on me again. I'll def check the fuses though and see if that tells me anything

If you look at the wiring schematics, the ecu and cluster lighting are nowhere near each other and are not even on the same circuit. So I know that is not it. Hook up an amp meter in line of your negative battery cable and with everything off start pulling fuses one by one. When you see a huge drop in amps, you have found your problem circuit. If you don't have an amp meter than you can make one out of an old school head lamp but then your not going off of numbers.....your going off of the brightness of the light. A test light can work for smaller shorts.
