Monday May 15th 8:34 AM.... Disconnected the positive lead to the battery and disconnected the battery trickle charger...
If on Friday I connect the battery and the car starts up normal then I know the battery is GOOD
If on Friday I connect the battery and the car doesn't start the the battery is BAD
If the battery is GOOD, then there is a parasitic drain from the car...
If the battery is BAD, then buy another battery ...
A reading of 12.65-12.77 volts means your battery has a full charge. 12.45-12.54 volts means you have a 75% charge, 12.24-12.29 is 50% charged, and 11.99-12.06 volts is 25% charged. 11.75-11.89 volts means your battery is dead.
5/15 10AM volt reading 12.84
Also checked for parasitic draw on the car... meter settings bellow...
one meter terminal to the positive terminal on the battery... other meter terminal to the positive cable going to the battery... reading was 0.10 .... I have a 110 MA draw on the car... should not be higher then 50 MA according the Eric the Car guy... His first suggestion is probably from alarm system... I need to disconnect system and check for draw again... but I blew the fuse on the meter so I need to get fuse first :)
