Ok i keep getting code 20 for some reason i dont know why. I relocated the battery to the back and it been throwing the code for like 2 weeks. The battery that was in the car
was good and me driving around it keeps draining it. Last night i put in my other battery
that works fine and it runn fine untill i go out and park my car and it get a week crank and doesnt start and loose power. Its not the battery and not the alternator cuz i changed both what else could it be i think it a bad ground on the back it where the spare tire hold bolt was.and a old stock ground. It get power like 12.30volt every where at alternator starter and battery and when i go to start it it just clicks and doesnt start or crank weak and the voltage jump to like 10volts.
Oh also where would be a good ground for the back and should i have more then one

 

Loose wire, bad ground ?

 

what i was thinking it was a bad ground some when in the back it a 89hatch and i need to find a good place to ground it. but thanks

 

Drill a hole, tap it, clean it off with a dremel, good ground.

 

Ok thanks for helping but it is not the ground on the back i have two ground on the back one where the harness grounds and the other is where the bumper bolt is so it is grounded so is the motor two or three ground there. Ok when i jump start the car with cables it starts up and works fine. Let it run for like 5min and shut it off try to start it up again and it wont start up again it feel to me that it wont recharge it self. I have replaced the ecu alternator starter the battery better ground bought a scope dual amp splitter for the positive battery cable because the battery is in the back. I have run out of thing to replace. I did a wire tuck and the relocated battery in the back but do not know why it wont recharge it self. It still trows a code 20 and that is the problem when it stops it will be fixed. I just dont know what else to check. When the battery are charge at parts store they runn for like a day and dont get more then 12.00volts.
Any input would be appreciated. Please help

bump help when i drove the car tonight after charging it i come to a stop light and when the green light come on the car want to shut off and it kinda takes a moment to re alive it back to life it is really fucked up the code 20

 

does any one know what could be causing it to drain and shut off the alternator charges it but still dies at stop lights could it be the ac gounds the i removed when u do a wire tuck or could it be the ignition switch.
