I have one of those ,and was getting a read out of
current overload ,and with that it would stop working . Applying the power to the HLD 350 ram directly , it worked fine , so the
books answer was a new PBC , and yes they have been superseded , but a J300X PBC replaced mine and it works fine , now here is the rub , I was still getting
current overload . as someone mentioned before , connections , first you should write down all your settings so you can reprogram the reset the the same , then pull ,of every connection you can find WD 40 them all and
work them in and out a few times ,reconnect all ,


then reset the program , and in my case , bingo it works again ,just looking at the connections wont do it they might look clean , and still not funtion , and in my case , I don't think I needed the new PBC at all , I left it in , but $800.00 could have been saved .Incidentaly I got the part through Wally at Custom
Marine Electronics , Shelter Island ,
San Diego , some of the other places just told me to get an udate $ 2000.00
