I have a fault code 27 on my onan 8000 gen sey in forest river berkshire motorhome
The code red to a low voltage or no voltage. First, disconnect your battery and check the voltage with a volt meter. If you have multiple batteries, check them individually. If you are getting anything less than 12VDC, your system probably will not even about to start; you may just get a couple clicks. If you have multiple batteries and one is strong, say anything over 13VDC, connect just the one and try starting. If the battery/batteries are strong and so nothing, ohm out the power cable(s) going from the battery to the generator "+" terminal; the cake should connect through a bridge before going to the battery or a disconnect switch. Ohm each cable individually when not connected s to anything. The readings on a digital multimeter should be around .02 ohms, which would be the same results if you touch the two loads of the meter together. The battery and cables can be easily replaced. If all these readings are good, the next thing to look at would be the transfer switch. That would be something more difficult to troubleshoot and you may want to consider taking your motorhome to a "reliable" camper shop or look to see if there are any Mobile RV certified technicians around.
