 Hi Vanagonians
 My local mechanic has deduced my intermittent stall problem to either
 the coil, a coil attached to the distr (forgot the name), or heaven
 forbid the ECU.  My bus has the wire harness fix. There is power to the
 main coil. (It has worked fine for several years but now the
 intermittent shut off problem is back) The trick is  having the bus make
 the problem long enough to get it to the mechanic.  Usually the problem
 goes away after a few minuites or hours.  Once overnight.
 It dies cold turkey with no spark coming out of the high tension coil
 lead but there is power to the coil.  Should I replace the coil first.
 I have not been able to do a coil resistance check because the problem
 has been so intermittent.\
 Anybody know if the ECU is testable?  Remanufactured?  Where is a good
 place to find one for the best price?

 Thanks
 Aaron

Hi Aaron, most likely the problem is the 15X power curcuit coming from the
fuse box to the 15 curcuit of the coil. I don't have the wireing diagram with
me to tell you what pin and connector in the fuse box to look at. But that pin
will have a burnt substance on it. The fix, is to butt connect that wire to a
new 15X curcuit in the fuse box. ( 15X means power with the ignition on ).
Your VW engineer should know what I'm talking about. If you need to know the
pin number, let me know. Michael Modl, 87 syncro.
