Check alternator. when engine is running there should be at least 14 volts or a bit higher at battery. when off at battery it should read no lower then 13 volts. check alternator, the pcm may have lost its power, so everything is going crazy.

Wires on grandam starter or alternator there is a wire not connectedon alternator it is a big single green wire

There are no green wires on the wiring diagrams for the starter or alternator. Can you see where it leads to? Could it be a wire someone added to power an aftermarket accessory? Are you having a problem with the car starting or charging? Please let us know how we can help.

I tried to charge my car battery with a Chicago Electric charger model 66783. I followed the directions for charging the battery in the vehicle. After selecting the charge rate of 10 AMPs, the ammeter...

Relax, the charger is working fine. What it is doing is charging the battery to 15.5V. During this time, the "charge complete" LED is off, and the current meter shows the needle going to the right. When 15.5 volts is reached, the current is shut off, the needle goes back to the left, and the LED goes on. When the battery voltage drops to 13 volts, the current goes on again, etc. At the beginning, with a very depleted battery, the needle will be towards the right, then as the battery gets charged close to full capacity, the needle will bounce back and forth because the charger is feeding current in short pulses. Towards the very end of charging, the needle will stay longer and longer at the left end (the LED will be ON), and spend less and less time to the right (LED will be ON for longer periods, and "blink" OFF less and less). Finally, at full charge, the LED will stay ON, the needle won't make excursions to the right, etc.
