1984 345: low oil pressure light and doorbell

[jdmii]

i just recently bought a 1984 345 le motorhome, i have a few questions regarding my coach. it has a 454 chevy engine, and recently the low oil pressure light has sporadically flashed on and off. what does this mean? am i low on oil? or is there another issue i need to look at?

secondly my coach has a doorbell on the outside handle, which doesnt work, the manual states the fuse is in the doorbell. i have pulled the button out of the handle and dont see it, i have also searched the coach top to bottom looking for a doorbell box, and cant seem to find it. if anyone knows where this is located that would be great.

The doorbell is located under the front couch, You can get access to it by opening the outside door that goes under the couch, it is on the right on the inside wall.
In regard to the low oil it could either be the oil sending unit, a bad ground or you are low on oil.
