Both ads imply the II is for negative ground only (assumed, I guess, if for positive ground they indicate it). Anyone know if there's a II for pos. gnd.?
Steve, these show only two leads, did you add a ground lead? If so, why?
Bob - the calverst.com article linked above makes the case that Pertronix problems are due to a sub-optimum ground. The author encountered this in 2 race cars and it was confirmed by the UK distributor of Pertronix. I ran a separate ground wire through the rubber leading out to the chassis at the coil mounting bolt. (My coil is bolted to the chassis). In this way, I'm circumventing all the joints between the distributor movable plate and the chassis, via the engine and ground strap. After I shot the pic in the previous post, I restored the ground line between the movable plate and fixed plate (belt and suspenders).
I believe the Pertronix II is neg ground only.
