<BODY bgColor=#ffffff>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>In my experience with
"high-end" MSD boxes, they do not tolerate much ambient heat. I could run
all day like a raped ape in my 'Clone in the winter! But, come summertime,
I would get most of the syndrome you've described.</FONT></DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4></FONT> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Ever since removing my
MSD 7AL-3, all such problems have VANISHED! Moreover, after chopping a
HOLE in the hood (for exhausting & pressure reduction while driving... no
more hood bouncing up and down either!), thereby <STRONG>dramatically reducing
underhood temperatures</STRONG>, I reinstalled the MSD and Voila! No more
problems... unless I run the A/C in gridlock... meaning it's probably best to
mount that MSD box <EM>inside the cab</EM>... somewhere away from the
ECM.</FONT></DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4></FONT> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>I'm afraid you wasted a
bit of change with those weasels at MSD since their unit's heat-sensitivity
problem results from their use of <EM>cheesy</EM> parts and bad heat-sink
design... all that crummy potting material! In most cases, the defective
circuitry exhibits only transient, recoverable misbehavior. Best way to
restart when hot: either bypass the MSD at the Coil (I use Jacobs'
<U><EM>Ultra-Coil</EM></U>) or lift the hood for 5 minutes or so... or try an
icebag on the MSD box.</FONT></DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4></FONT> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Try it and see if I'm
right... assuming you've installed the MSD under your unvented hood! If
it's already <EM>in</EM> the cab, please disregard all the
above....</FONT></DIV>
