Turbo after run relay fix

Hi all,

Just fixed my old turbo after run relay last night.  Since I just got my
new one from Greg at GPR, I wanted to keep the old one for a spare, so I
popped the plastic can with a pair of jeweler screwdrivers and found that
the output transistor that drives the aux. water pump had fried.  Replaced
it with a commonly available MJE-200 transistor, soldered it back in and it
worked just great!  Gotta watch which way to install the transistor as I
put it backwards the first time.  Taking it back out destroyed some traces
which I repaired with some bus wire.  BTW the easy way to test if the aux
pump is running is to pull the #8 relay (1st stage rad fan relay).  You can
hear the coolant pumping through the hoses quite easily.
