update: no power rear load centers? 82 FC 35 SB

[Ralph L. Fullenwider]

If I reading your response right, you do have Master power to the load
centers. So looking further for the Master breakers should be a dead issue
there.

Some times, getting a good connection is hard, thus the scraping to get a
clean connection. We need to go with your test light hook up one way only,
the alligator clip goes to ground and the probe is touched to hot or what
should be hot, circuits.

Do you have the manuals in the blue box or where ever they are kept? In one
of the manuals there should be diagrams of each load center. The left rear
load center is where the usual spot is for the fresh water pump voltage
source. Usually it is a green wire and either number 3 or number 9 for the
wire number. We need to find that source. Then double check the in coming
master power to that load center and I think it should be hot, after
reading previous posts. Some times a glass fuse was used on the fresh water
pump source and other times a resettable circuit breaker.

Your doing good, just remember to be sure there is a good ground source for
your clip lead.

Oh, the master breakers should not be in the overhead, and if not located
at the base of the steering column then perhaps they are in the lower front
load center, usually located behind the drivers side head light pannel.
