94pt shuts off in traffic

[Gregory OConnor]

traced wires to the ig::
The "engine compartment light" shares a breaker with both ig
switches this may be the issue (three wires off this breaker). If
the engine compartment light or the bay door switch to the light
keeps tripping a fuse, you are screwed the light wires are protected
by the breaker tripping and the bus stops. there are several
breakers in the back (little silver boxes with two 5/16? inch studs)
under and around the big reed copper shunts along the wall above the
3 start batteries. power to the ig switch is via this 40 foot long
wire 'orange and black'.

I think I will lablel all three breakers ;then replace ;then pick a
new big wire source up near the cockpit to send 12 v to the ig
switch ( add a 20 amp breaker there also). the small wire is
sufficient to run the power to the ig switch because the ig switch
(key) only need little amperage to flip a larger 75amp relay. but
there are just too many things that can happen in 40 feet and the
compartment light is just one more error prone item that can cause
collateral damage.

other computer issues have arisen in the past with the breakers in
this area. While roadside, RobR directed me to jump one for a limp
repair but removal of that breaker did not cut power. (Rob was
close) it may be heat deterioration in the breakers or the fact
that I dont close the engine compartment door all the way to a solid
lock because the clasps are not aligned???? so now is the time to
replace all the crap back there. I prob will put the breaker in the
same spots but for sure will move the source of 12 v to the front ig
to a big wire in the cockpit area.
