Iím a newbie when it comes to this stuff. I had a 2nd battery installed along with a Perko switch to run my amplifier for my stereo a while back. I just had a second amp installed to run my highs and the guy that installed this amp is telling me that he believes that the perko switch setup was installed incorrectly. We checked the batteries when he finished installing the new amp and one was showing about 13 volts and the other about 9 volts. The original guy that installed the switch told me that I only had to charge one of the batteries and both would get charged. He also told me that it didnít matter what setting I had the perko switch on that I could start the boat and listen to my music with no problem. This didnít seem correct because I would think that position 1 is to start, 2 is if I want to park the boat and listen to music or all is if I want to drive around listening to music. Here are some pictures of my wiring setup. The diagram seems kinda easy to follow but that only has one wire to the battery and one wire to the switch. As you might be able to tell from the pictures i have several wires to the battery and several wires to the switch. The first 3 pictures were the original setup and the last pictures was the new amp install to the battery.
I know this is a lot but can someone explain or preferably give diagram or picture of setup. Thank you.
