Re: Brown DeLo Wires

["content22207" <brobertson@xxxx>]

Actually just about everything before main & aux relay's (and a few
circuits that baypass them) is brown. Good rule of thumb whenever you
see a brown DeLo wire is "always hot, always on".

Fuel pump relay is hot whenever fuse 7 in place, whether or not car
energized.

Rich is right: you need a wiring diagram AND the legend. Then you need
to study it in comfort of your own driveway. Time to figure out how
various circuits work is NOT when car is dead on side of road.

FWIW: almost entire car can be driven from relay compartment. Keep 2
and 3 way jumpers in the glove box for those emergencies.

My pet peeve is headlight circuit. Dash switch NOT circuit protected
(hazard switch is, but not headlight), yet has a load bearing device
inside (illumination bulb). Mine melted internally, shorting to the
bulb's ground. Without fuse whole switch went up in flames. Results in
#5939's photo album. You may have had smoke -- I had fire. Very bad in
a plastic car.

Better get used to DeLo wiring problems. They pop up from time to time.

Note most circuits that are switched on the hot side in domestic cars
are switched on the ground in DeLo.

Get a wiring diagram...
