I did a test on my batterys and found that my audio batt dropped to 6 volts under a load and my other batt only dropped to 10.
So I bought a heavy duty deep cycle and decided to replace my audio batt. When I pulled to stock batt out of the battery case I found about a quater inch of battery acid in the bottom of the case.
BINGO, I believe I've found the culprit.
Going to try it out this weekend, I'll let yall know how it goes.
