Salvaged MAC 11B ECU Working OK

["Douglas Hurst Quebbeman" <dougq@iglou.com>]

When I disassembled the ECU last night to consider why it did not
work, I noticed that I'd gotten both of the transparent gaskets
(which go between the aluminum frame/heat sink and the four
large transistor/semiconductor devices) between one set of two
devices, leaving the other set of devices in direct contact with the
frame.

Thinking, if the gaskets were the thermoconductive type, then
my misplacement of the gasket might not explain anything. But
if the gaskets were electrically insulative, and if the frame is 
not supposed to be at the same potential as the tab of the 
transistors, then shorting them to the frame might disrupt the ECU's 
operation (this could have been one of those experiences that 
liberated the smoke hidden in a device, but that didn't happen).

Attached bare naked ECU to connector and vacuum, started,
ran fine, in fact, (and this must surely be my imagination)
seemed to run a bit better. Boost reached 1.3, same as my 
original ECU.

Scott M., I think your messages should reach me now.
