[Double Venom]

Bob,
Good question, see where your coming from. ALL Neutral Safety switch(s) have/has been taken out of the equation!

Owner finally in the shop yesterday, came walking in with rheims of papers, notes etc. Still has the same problem!

During conversation a wee bit of evidence may have creeped in ?????
Under the dash (This car has been on the road successfully for over four years!) looking for any indication-s as to why! He tells me the large purple (Neutral safety wire on this type harness!) wire appeared to have gotten hot and partially melted the wire next to it. AaAHAHA, Now I / we have a clue, wont know until he gets the car here. Any one else care to give an educated guess/ answer?
