on a side note with the s10,I was trying to fix my tuner and noticed the xtal leads on the tuner were dangerously close to shorting out against the metal on the cam socket.I took a pair of cutters and trimmed those leads and other cap leads that were way too long.In one instance before I cut them, the leads did short out.If you pop the tuner out to put in a varistor,check the lead lengths on the bottom of the module.
