I think it is a good idea also to address all the ground
connections while you are servicing each module. The
chassis, being make of aluminum, oxidizes and makes
poor connections. I loosen up the ground and clean
the connection point then use Ox-guard- or other aluminum
electrical connection compound.
Use of a compound for aluminum electrical wiring is a must, and aluminum
house wiring has a very high failure
rate because of the oxidation of the wiring.
