Customer Question

Just bought a 1988 Carver Riviera aft cabin 2807 boat. We noticed that the Bilge BLOWER was not working. While we were trying to figure out why we found that the Cabin fan (just an on/off switch) was not working either. When we turned on the Cabin switch it popped the fuse. Are these two tied together some how? We purchased a new blower for the Bilge while it now runs it runs constantly we cant get it to turn off and we replaced the switch. We still cant get the cabins fan to work it continues to pop the fuse. Since they seem to have went out together we are wondering if they connect electronically to each other or something we cant find the wiring for them

Hello, my name is***** will assist you. The two systems are not connected together. You do have two separate issues here. On the cabin fan, there is a short in that system, most likely it is the fan motor itself. To test this, disconnect it, then replace the fuse and turn the switch on, if it does not blow the fuse, replace that fan motor. On the blower, remove both wires from the switch, then make the connection to the blower or turn on the battery, how ever you had it running before. With the switch disconnected and if the blower still runs, you have a short in the harness going to it. If it does not, reverse the leads connected to the switch and see if you can control the blower then with the switch.
