rob,

it hasn't had an alarm fitted has it?  some of those installations use cheap
1-wire switches using the chassis as a return, and looking for voltage drop
across the interior lights???  took me 1 week to find a similar issue in my
ur-q.

all the best,
dave.

I'm trying to close the deal on this '88 5kTQ that a friend at work wants
to buy, there is however a problem...  The battery is being drained down.
I ran a charging system check, and it passed.  I had the battery load
tested and it failed.  Woohoo!  Replaced the battery and problem solved
right???  WRONG!

So I've done the "yank fuses while watching the test light" drill and found
the following:

Fuse 4 - (Interior Lights, Radio...) is the main culprit.  Put it in and
there's draw.

But it gets worse...

Once the draw is started by inserting Fues#4, it will not stop until you've
pulled Fuses #2 and #3.

Without #4 in place, there are no issues.

Can anyone thing of a common place to look where all those circuits
interact???  I just doesn't make sense except for maybe the fuse block...
