I am looking for assistance solving a bass volume control issue with my Sega Harley Davidson L A Riders Deluxe. The bass volume is always at maximum and can't be reduced with the volume control potentiometer (the bass amp drives two Aura rumblers, one under the seat, and one at the handlebars). The separate sound amplifier board and volume control works well & I found that it's volume also goes to maximum when the volume pot is disconnected from the system. Following that logic, I tested and verified that the bass volume pot shows proper resistance (0 to 5000 ohms) at the bass amplifier board. A schematic of the bass amp board would be a big help. Any ideas or suggestions would be appreciated. Thanx, Denny
