The oil level sensor is a vital piece of equipment to save your engine when the oil level is too low
talk with generator repair shops as the sensor is generic and you may be able to get a good unit that fits another brand
you can test by bypassing it
however check the fuel flow through the metal tap as the corrode internally and block the flow of fuel--especially if you use e-mix fuel
the oil switch is screwed into the sump near the dipstick with 2 wires running back to a small box about the size of a match box
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Depending on the chassis manufacturer I would immediately suspect the ignition module. On GMs they are sometimes mounted on the steering column somewhere around the bottom dash level. From the actual ignition Key slot receptacle there is a mechanical metal rod that connects to the ignition module. The module sometimes become loose and move or slip. Or the module may have become defective. Good place to start looking. Easy fix if that is what it is.
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.
i am asssuming that you are talking about your coach battery bank.are they 12 volt or 6 volt battery system. the arc is a short. check polarity. can you charge the batteries with an external battery charger? if so. then need to check converter output from your mian power panel. there are a few other things to check. need more specifics. and you need to have a volt meter handy.
Check for a bad ground - causes weird readings especially when using a digital meter. use a cheap analog meter that draws a bit of current. digital meters can give you confusing readings like showing voltage when there's nothing readable on an analog meter.
