'84 4KQ fan, relay, fuse panel solved
Well, after many horrifying revelations with a razor knife in the wiring
harness, I hereby rescind all evil incantations against Campbell-Nelson
auto wreckers. The fuse-relay panel and ignition module they sent me
continue to work super-cleano. Now if I can just get the damn thing to
run when hot, I'll be satisfied.
If anyone has any questions about the wiring to an '84 4KQ cooling fan,
direct them here, because I have been through hell and back with mine as
a result of terrible green corrosion inside my fuse panel that blasted
all four wires, melted about 10 feet of harness, rendered my engine
electronics dead, and required me to inspect/replace/retape/reconnect
everything associated with them under the dashboard, forward of and
behind the firewall. I hit a bump and that jolted something enough to
let current flow freely where it was never supposed to go.
The car just escaped catching on fire when I nearly went blind from smoke
and shut it off in the middle of Chicago. All is OK now and the
night-sweats have stopped, mostly. I would advise anyone who owns a car
of this type/vintage to lift the fuse/relay panel and inspect it
underneath with a dentist's mirror for corrosion. I got mine used but
clean for $65. The consequences of missing it are really not for the
faint of heart. If your fuse box seals well, you shouldn't have any real
problems, but mine looked as if someone poured acid into it.
My local, very competent but expensive Audi mechanic modestly asked
$1000-1500 to fix it. I decided that it was better not to pay him in
Monopoly Money (read: credit cards) or let the car sleep with the fishes
in Lake Michigan, and instead Rollerbladed to school for a while and
fixed it myself for $150 total, parts and labor. Not counting the nice
digital multimeter I bought, which is good for fun and games anyway.
The car was East Coast in its youth, so that might have something to do
with it. The previous owner from whom I rescued it wanted to RAISE the
suspension so it would HANDLE snowdrifts better (yes, he also put 225
tires on 6-in. rims for better grip, please don't ask me why or how), so
who knows if he ran it over a few Atlantic sandbars during the warmer
months and gave it some Statue-of-Liberty type misting just for kicks?
Thank God the driveline of this car is virtually indestructible at the
power levels it has to cope with.
The fusebox is a simple, plug'n-chug replacement. Needless to say, mine
is well-sealed now.
The rest of the car is in great shape, really! (I keep telling my
girlfriend, but what does she know?!) No dents, dings or rust, a nice,
sweet sounding exhaust and that low, low '84 gearing! I drove it 30,000
miles before Chicago with no problems, but now a cascade. Ride it out, I
