shore power vs generator

[Gardner Yeaw]

All fixed!

The wires leading from the control box to the gen brushes were
chafing where they pass between the generator main housing and the
rear housing where the brushes are. The M1 wire was burnt in half
which explains why the circuit showed open. I replaced the wire and
reinforced the shield, but the passage is so narrow there is no room
for a heavier cover around the wires.

The fact that the control box mounts had failed allowing it to
move around probably lead to the failure. I had made new mounts a
couple of weeks ago, but obviously too late.

I have some pictures I will put up once I re-size them. It was a
long day getting the genset out so I could work on it. I had to
build a platform to rest it on and fabricate a special tool to allow
me to drag it out in a controlled fashion, and reposition it when
putting it back in. Basically a piece of 1x3 oak with a slot cut on
the face about 2 inches back from one end, and a series of holes
which allowed me to hook the wood on the generator tray and slip a
screw driver in one of the holes to pry against the edge of the bay.
That way I could inch generator out in a controlled fashion and save
my back in the process. It worked pretty well if I do say so myself.
