My 911 997 c2 is having a difficult time turning over. Seems to get worse the more I use the car without putting it on a trickle. I have already replaced the battery once but something has the be drawing or going??
Help

 

There is an alternator/battery cable issue where full charge is not reaching your battery, it is discussed here frequently. The cable connection apparently builds up resistance with time.

 

How do I fix it?

 

Measure your battery voltage while engine is running, it should be above 13 Volts, if it is around 12~12.5 then it is not charging properly.
If it is due to the cable then it should be replaced, from what I've read it is labour intensive and pricey. Another option could be your alternator has failed.
Suggest auto electrician checks your alternator output.

 

I had the voltage checked. Never jumped while running past 12.3. So I will have the alternator and cable checked. Is there a DIY for the cable somewhere with pics?

 

i think someone just posted one on here but i can't seem to find. there is one over on renntech also. search there. it is involved but if you're a wrench, it probably wont be too hard. just time consuming.

Turned out to be the STARTER.
But it could also be the Alternator/cable...

 

Just did my cable, car had four batteries before I bought it. Starts much better!
