Hello Sea Ray lovers and enthusiasts,
I started adding smart craft equipment to my single Mercruiser 5.0 MPI unit. I installed the SC1000 gauges, reconnected the fuel gauge to the purchased additional harness for two tanks (3-pin plug with two pins at the back of the engine, pink wires with a black stripe and ice blue with a black stripe ) as it is possible to have two gauges, I wanted to except the first one with fuel (this gauge works, the error in the engine turned off) have a second one for clean water. And here is the problem on the first pin I have 5V and on the second there is nothing, i.e. no voltage at the output from the plug at the back of the engine. does anyone know where these pins get the voltage from, does something need to be activated in the PCM555, maybe there is a fuse somewhere?
