Tony....it has been a quest equalled only to that of finding the grail!

The FAQ is dead on as the problem comes and goes when the car (a miata which gets jarred when hitting a rock!) goes over any bumps in the road.

in fact i am sending it to Stu to have the internal ground checked out for after all these years maybe they have come loose as well

for now it is VERY odd that even without the player in the sled...so..like suggested...a wire must have come loose in the connector on the sled
