Subject:      Re:No Spark in digifant

Van Run 	Man Happy
	After taking everyones good advice and following the bentley book again
and redoing the grounds again,  I checked the whole harness for grounds to
non-grounded wires.  All OK. then i was checking for shorts to each other
and i found a short between two of the hallsender wires.   after digging
into the harness i found a sheilded wire that goes to the Idle
stabilization Unit and found that the sheild was shorted to the wire. after
cleaning that up she started right up.  Whew no ECU purchase needed. Thanks
for all the help i find the list just the crutch i need to keep this
wonderful machine running.
