- VS Calais V6
Hi,
I am currently not able to start my VS Ecotec V6. I have tried 2 different batteries both fully charged at 12.6 volts which then start the car and it reaches 14.2 volts on idle.
Both batteries are not brand new however I wouldn't expect such a fast voltage drop from a fully charged battery.
When the car shuts off, the voltage drops from 12.6 to 12.0 and eventually will drop to 9.0 volts meaning the car won't start. I used a multimeter to test the alternator and battery and all have good readings. I cannot find where this drop in voltage could be coming from. Connections look fine, terminals are clean.
One other potential point is the negative battery terminal which will not tighten around the battery. Does anyone else have the same issue? I use a brass connector which seems to fit fine over the positive terminal but very loose on the negative terminal. I haven't found a version like the original that will sit securely. Should I use a battery lead shim?
I have attached 3 photos:
Photo A - Positive Battery terminal. Petroleum jelly has been applied to the positive post to prevent corrosion.
Photo B - Negative Battery terminal. Petroleum jelly has been applied to the negative post. This does not tighten like the positive terminal and could easily be removed by hand.
Photo C - Negative battery terminal on a negative post of the battery. Is there an alternative version or company that makes one that fits tightly? Is a battery lead shim an option?
If anyone has advice or can spot something that isn't working here would be greatly appreciated.
Thank you
