Ok everyone, I have replaced the battery, the alternator and I still am not getting a charge and my battery keeps dying. I've cleaned the battery terminal and made sure everything is plugged in properly. Any ideas?

 

Parasitic drain?
Any after market parts that could be doing this.?
Trunk fully closed ?

Do you have a battery charger / tester?

 

Be sure your terminals are TIGHT.

 

I have literally checked everything. The only thing I haven't checked which I'm doing today is the ground wire. Nope no aftermarket add ins either.

 

If you are still having this issue,
When you start the car, what voltage are you getting at the battery? 13/13.5/14 volts is good and you probably have an issue with something draining your battery when the cars off but if your getting 12.5 volts or lower then there's an issue in the charging circuit. On the Rx8 the voltage regulation is controlled by the ECU, i would have to check the drawings but there would be a few wires you could test etc if that's the case .

 

I have a mechanic coming out today to do the tests and do a diagnostic on it.
