Hi Phil,

My 251 907 393C was bad and had no signs of burnt components or broken solder joints.
Went looking for used units. Found two that sellers said worked Ok when removed. One I tried
didn't work in mine or worked as bad as my original 393C. The other worked when cold but not
with the engine at normal running temperatures. Both 393C modules. Opened this second one up
to look inside, nothing visibly wrong on the two boards inside.
Bought a new one *393D*, ISV works as per sec now. So, there is my ISV experience to date. Was
going to call it my two cents worth but, the thing was like $289. Canadian...

Oh great name Phil,
