Electrical Issue R33

[GT500_Racer]

Hi guys i got a electrical issue that has me stumped, ive checked all the fuses and relays, ive replaced the alternator as well figuring that it wasnt charging at 14 volts, and battery yet still same problem....

When the car runs its draining the battery to the point where the car dies, the battery sits on 11.4 volts when the car isnt on, but once u start it up the battery is drained,withing 15 mins

ive checked all earthiing and removed my amps and gauges to isolate the issue to only just the oem wiring, yet the problem is persistent

any help is appreciated cheers

What voltage is battery when car is on? Does your battery light come on when u turn ign on? The batt light on dash acts as a excite trigger for alternator to start chraging when car switched on so if light isnt on it wont charge
