David,
With all due respect, you make the electrical system sound like a total
basket case. Yes it has a few problems but some of them are self induced. We
wait till the blower motor to go out and draws almost twice the current and
over heats the CB and maybe scorches the wires before we replace it. Same
with the fuel pump and #7 fuse. We can't blame mother nature for getting
grit and grime into parts where we don't want it. I don't know of any mass
market car manufactures of that time will make a bullet proof wiring system.
We just have to use some common sense with it and update it according and it
will be fine. Again, as you know were dealing with a 20+ year old
technology.

The electrical system in the Delorean leaves a lot to be desired.
First of all there is NO fusible link. There are way too many unfused
lengths of wire. Many of the circuits operate at maximum capacity with
no reserve for age deterioration (loose connections, dirty
connections, etc). Some of the relays are underrated and have frequent
failures (the door lock module and the fan fail relay for example).
Add to this a P.O. using the wrong size fuses, wiring modifacations,
age, loose fuse holders, An aging fuel pump that draws too much
current (and the cooling fans, and the heater fan) an alternator
running near it's maximun limits and a system that is chronically
undervotage. All of this causes the current to increase which means
HEAT. The only sensible approach is to at least keep everything in
good working order. Make sure that each and every fuse is in the right
place and is the right size for it's spot. Disconect the locking
module. Remove the fan fail relay and at least use the jumper wires.
(Not the best thing but better than the relay).
