Re: [DMCForum] Bah humbug! Santa brought me a melted fuse box...



Travis,

Fuse #7 has nothing to do with the cooling fans, so you have more
electrical
gremlins to sort out.

I recommend wiring around the fuse block with a "pig tail" replacement
fuse
holder.

Learn from other people's mistakes.  I have seen plenty:
1) Be sure to use a heavy duty fuse holder that has 12 gauge wires.  Do
not
accidentally get a light-duty one that uses 14 or 16 gauge wire.  Those
will
melt.  The best fuse holder for the job is made by Belden for NAPA.  It is
part # 784619 ATO/ATC Fuse holder heavy duty.  Otherwise find one that is
made to hold an ATC-30 fuse.  If you use a cheapy fuse holder, you may
need
to slightly crush the female spade lug connectors to get a tight fit.

2) Avoid using an exterior grade fuse holder with the weather proof cap.
The DeLorean is made to run too much current on many of the 20 amp fuses,
so
any socket may tend to get hot and melt.  Weather poof caps tend to hold
this heat in and make matters worse.

3) If the fuse block got hot enough to melt, then it most likely damaged
the
wires, too.  Do not attach to the wire unless it is clean.  It should be
bright & shiny.  It may be necessary to cut off a few inches before you
find
clean wire.  If you feel that you may have to cut the wire too short then
consider cleaning the burnt wire with acid or abrasives.

4) Do not trust saddle splice connectors, wire nuts or pre-insulated
barrel
crimp tubes to connect the replacement fuse holder.  It is best to start
with a non-insulated barrel crimp connector.  Crimp it first, then tin
with
solder.  It is bad practice to crimp a soldered wire.  But if you do
anyway,
re-melt the solder after you crimp.

5) For a professional look, insulate the connections with heat shrink
tubing.  Electrical tape usually looks sloppy & amateurish.

6) Properly label each wire with electrician's numbered tape.  A book of
these is available at such places as Home Depot or Lowes.  Use numbers
that
match the fuse number that the wires connect to.

While you are messing with pig tail fuse holders, make up an extra with
1/4"
male spade lug connectors and keep with the car.  They come in real handy
for bypassing/trouble-shooting a variety of problems such as bad
otterstats,
headlight switches, a/c fan relays, etc.

John Hervey is the only guy I know who has come up with a fuse block
replacement.  If I were to go to that much trouble, I would divide up the
load better to put fewer circuits on each fuse (which of course would
require adding additional fuses).
