I have an SVR deep cycle battery and a system. It keeps getting drained for whatever reason.

I assume it because of my system somehow. So I unplugged my system power wire and see how long the battery last this time.

I did unplug my postive battery connector while the car was running and it continued to run, so I assume the alternator is working.

Do you think my alternator may not be putting out enough juice to run the car and charge the battery at the same time. How do I test the alternator?

thanks

 

go to a checkers and have them do a test on your alternator.
do you have a capicitor for your system?

 

No Cap.

 

Maybe there is somehting grounded in your accesories like radio or something that keeps on working even if you turn off the engine. try disconnecting the battery at night and try to start it in the morning if it starts then somethings wrong with your wiring system.
