Two unanswered problems:
1-House battery - low voltage problem
Went fishing Saturday and all voltages showed 13.8 VDC on the garmin GPS. In a previous conversation with Mac, he told me that one engine will charge all three batteries thru the isolator.
Crank port engine (Volvo 7.4) and the voltage meter will show just to the green arc but not into it, Garmin shows 13.2 VDC slowly rising to 13.6. Turn on the STB key switch, port meter drops back to 12 away from the green arc ????, why??? Crank the STB engine and the voltage stays at 13.6 VDC, so the engines are charging, but the port meter never goes into the green, STB does showing 13 volts. So the system is working just not showing on the port meter.
Anchored up with some friends Sunday, shut the engines down and left the AM/FM radio playing. After about two hours the radio started cutting in and out. Voltage 10.8 VDC. First thought was a bad house battery. left the charger on over night and removed the battery the next day and carried it to the battery shop. Under a load it worked just like it was supposed to do. I had this problem at a Christmas flotilla and replaced the battery. Now it reappears again. Something is draining the battery, any suggestions?
One CC owner said his was doing the same thing and it was the shower pump stuck. Dumped 3 gallons of water into the shower and it pumped it out, so the pump is good. Where and how do I start testing?
2- generator runs and cuts off.
Onan generator will run from anywhere from 1.5 minutes to 1.3 hours then sounds like it is starving from lack of fuel. It starts loping and then shuts down in 15 seconds. It is tied into the port pickup on the main tank and that engine does not have a problem. Replaced the carburator several months ago, filled with crud, I guess the boat sat for an extended period of time. I'm going to remove the tank pickup and check that out. It may be the Onan doesn't use the volumn of fuel that the Volvo does and the strainer may be partially clogged. Am I on the right track?
Don't you just love buying other peoples problems!
