99 Bayliner Capri 1850 LS Electrical Issues

[corey4631]

I was wondering if anyone would know where I could get a wiring schematic for the a 99 Bayliner Capri 1850 LS.

I installed a new stereo in my boat which involved running several wires to and from the stereo and battery along with the amplifier. Now everything on my dash works, except for my fuel gauge?!? I thought that was kind of weird, until I also noticed rear blower to get rid of gas fumes did not work either. I also noticed that the bilge pump also does not work.... I checked all the fuses up front and they are all fine. All of the electrical things that are not working all run to the rear of the boat and do not go to the fuse panel up front. Is there another fuse panel in the rear that I missed??

I would love if anyone knows where I can get my hands on a electrical schematic for this boat! I obviously have probably unhooked some connection along the way, or blew a fuse!

You don't need a wiring diagram. What you need is a logic approach to finding the issue with EACH thing that doesn't work. If it worked before you did the wiring, then retrace your steps as you mucked up the wiring somewhere. Things that don't work don't have power. So start at one end of the circuit or the other and check voltage along the way. If you start at the LINE (input) to the switch and you have power, turn the switch on and check for power at the LOAD (output) side. No power you have a bad switch or a bad connection on the switch. If you have no power at the LINE (inhput) side there is a bad fuse or connection between the panel and the switch. If you have power on both sides of the switch check for power at the device. No power there means the wire between the device and the switch has an issue. Always make sure the device is properly grounded. All other devices work the same way. +12 volts into fuse, then to switch, out of the switch, to the device, through the device to ground.

The fuel gauge needs +12 volts, ground and the signal from the sender in the tank. There are over 100 posts on fuel gauge problems in this forum most of which have a diagram. Use the "Search" feature using Fuel Gauge Problem as keywords.
