parasitic drain by Alternator Options

[yellowchinaman]

At first I thought my battery wasnt holding its charge. But with my new setup I found out with a multi meter that power is dropping as soon as the engine is off.
I did a parasitic drain test and discovered that by dis connecting my alternator, it stopped dropping!!!
WTF????
Can somone pls explain as to how its possible my alternator is draining power when off?

I located the battery he's using, it's only rated for 6 amp hour and 150CCA which is awfully tiny for a car to use, especially with ignition off draws. Assuming a 30 miliamp draw it would take about 20 hours (6 amp hour/0.030 amps draw) to drain the battery flat dead. I believe that battery is just too small to use in a car. 30 milliamp is assuming the normal draw for a stock car with no add ons like alarms or aftermarket radio's that consume more power with the key off. I do hope it was just a bad alternator and not the battery being too small, and that my math is wrong.

I forgot a zero, 200 hours until totally dead, but at 1/2 capacity I doubt that battery would start the car.
