MAC11b ECU Trials & Tribulations



On Christmas Day, I finally engineered a way to pull codes by
modifying my "bogus" fuel pump relay. The salvaged ECU worked
fine on the output tests. But then I went for a run, so I could run 
the input tests, and I got a knock sensor (2142) code. 

Removed the unit, replaced the car's original ECU, and went for
a ride. However, before going on the run, I poked around under
the hood, grabbing wire harnesses, trying to isolate the path for
the knock sensor's cable. So, of course, I got no codes after the
second run, possibly due to my having fixed the problem (if
it was an intermittant wire break).

So, I put back in the salvaged ECU, but oops, I think I bent that
transistor a little too far, yup, snapped off an NEC C2334
into my pissed-off fingers.
 
The little bugger crosses over to a TIP 41C, but wouldn't you
know it, NO electronics stores open Friday or Saturday other
than ReamMe O'Shack, for whom a TIP 41C is a special order
part.

And Monday goes by without me even thinking about it.

The saga continues...
