So, I have a Helix 10 which is from when they first came out. Everything works great still except it continually shuts down due to low voltage. I traced the voltage from the battery through fuse box ect, and have high 12 to low 13's right up to the head unit. The power port male side has good voltage but when plugged into the head unit the head unit only read 10V or less usually, on a rare occurrence I may see a 11v reading but rare. I have cleaned all connections and no change. Anyone have a solution to this issue?
