As some of you may remember, a couple months ago I posted a couple times
about a 5 amp drain on my 89 Taurus that was impossible to find. Yes, I am
still working on it, even if just on principle. I did get alot further, so
once again i'm asking for the opinions of you mavens out there. To recap
the situation: Car drove great everyday until I came out one day and the
solonoid just chattered endlessly. Replaced the battery, worked great for
one day, back at square one. Put an ammeter right off the battery cable,
and found that the car was drawing 5 amps (4.55) with the key off. So far
i've replaced the battery, battery cables, starter, starter relay, and EEC.
As it stands now, to isolate the short I need to disconnect the wire going
to pin 1 of the EEC, and fuses 1 and 8. Connecting ANY of these will cause
the drain. Disconnecting all of them will cause it to go away.
They all seem pretty unrelated. Fuse 1 is brakelights and the like, fuse 8
is courtesy lamps and the clock and stupid shit like that, and the other
wire is the keep alive power to the EEC. I'm almost convinced that it's a
pinched wire somewhere, but I was wondering if anybody had any suggestions
on how to isolate a bad wire in a car with probably a mile of wiring that
could conceivably be ANYWHERE.
As always, any and all help is greatly appreciated.
