Ok here goes I got my porshe 76,oookms
It runs strong and fast int good panit is faded but body is great.
Now the nightmare Put new alt,Battery and Positve-Negative cables on it however never replaced the ground for motor seems not bad. I replaced the relay for light motor because it was not folding down sometimes minutes later it would that never hellped thurgh.
Basicly u drive during the day its fine till moring battery is dead in the moring or if u hit lights at night kills battery after hour driving.
so iam stumped other problems are sunroof wont work going check relays on that for motor. I replaced all fuses in fuse box but not the relays .I notice the wipers come on sometime as well when u use turn signal.
I also took the deck out for the stereo because this was wired wrong
. I know he put an after market front clip on it so i will check the wiring there next .
If anyone has had this these problem hit me up

 

Take the alternator and have it checked,you could have gotten a bad one or it could be the wrong alternator or even hooked up backwards.
