Charge the battery with the ground wire disconnected from the battery, then check the voltage on the battery after charging (with the ground still disconnected). It should be 13V or more. Then connect the ground post and see if the voltage drops.
If it does, you have a device drawing current that is responsible for the problem. It is an easy test. All of this done without the key even in the ignition!  |
I don't understand how you charge with positive only. Is that even safe? It has never had this problem before, and likely it is just the battery sitting for so long it went down to 3.1 volts that killed it. I just charged it again overnight with my normal charger, and same story; as soon as I removed the charger it read 11.6 volts. Only makes a relay sound when I try to start it. I'm thinking a dead cell.
Ordering new battery off Amazon today. Is Mighty Max considered a good brand? They also sell 'em at Home Depot and Lowes, so that is a good sign at least.
