Engine Room Temperature

[Gregory OConnor]

The 94 engine compartment is loaded up with about 10 cb's the
problem I found was water passing the hermetic seal on the cb. I can
see where heat will be an issue because there is a thin piece of
metal that holds the contact point against a lug in the cb. I
believe it is heat that causes the metal to distort and move away
from the lug.

I wonder if fuses are not a better protection. with a fuse, a ground
short will pop it and you will have proof when you do the 10 second
pretrip taillight test. it could be that a cb opens up 30 seconds
after you set out on the road and resets itsself for your next
pretrip check.

gotta be a reason they (auto engineeres) use some cb's and some
fuses???

I like the way you isolated my trailer light power from throwing my
bus tail light power.
