well, i haven't been hanging from a tree on meathooks.
different strokes for different folks, i guess.
well, i've been doing the college thing and the job thing, and since
we've been a little light on journals lately, i've decided to
take a break from homework and do the journal thing.
a few journals back (i think it was liclit's), we were talking about
electrical problems. there haven't been too many journal posts lately,
so it shouldn't be too hard to find.
well, i got this job recently and it was pretty much the electrical problem
from hell
Basically, the anti-lock braking computer burned up... i mean literally.
(it's the bottom computer in the photo)
this job is interesting because it originally came in because none of the
dash gauges worked. no tach, no speedo, no volts, no oil pressure, etc.
what does the dash gauges have to do with the ABS computer? i had to figure
this one out for myself, but it basically breaks down like this...
dash gauges in modern trucks (and cars, for those taking notes) aren't
wired in the old-skool fashion, where the volt gauge is wired to the
alternator, the oil pressure gauge is wired to the oil presure sender, etc.
etc.
everything is sent to the engine computer (which needs the
information), then the engine computer sends the information out over a
network where it is picked up by the 'dash gauge' computer, which
displays the information on the gauges.
the anti-lock brake computer also sends and receives information over this
network.
when the anti-lock brake computer burned up in this truck, it basically
left the phone off the hook (an american phrase). none of the computers
could communicate with each other.
unfortunately, it also burned up all of the wiring and harnass connectors
along with it.
although this is one of our oldest trucks (it has over 1 million miles... i
have no idea what that is in kilometers... probably something aroun 1.5
million) federal law demands that this anti-lock computer and the dash
gauges all work, so failure was not an option.
so i spent the better part of the day wiring all of this shit up and
testing out the finished product.
yeah... i hit you all with a wall of text. oh well, if you don't like
it... POST A JOUNRAL OF YOUR OWN.
we've been a little light on journals lately
and yetti... quit sticking things in you that aren't made out of flesh
or latex... it's bad karma.

well... the computer was given to us for free by Bendix due to a
recall, so the only parts involved are wire, connectors, terminal
ends, etc... and about a full-day's labor
now if we had to buy the computer, it probably would have been in the
$600 - $1000 range.
what have i been up to lately?
