MG MGA - Pertronix positive ground static timing

Can't find this in the archive...I have a pertronix Ignitor 12volt positive ground. The timing light connections will be different from that of a points ignition. How do I connect my test light to check/set static timing? 1962 MGA MkII. Thanks, Randy

Can't, must be strobe timed.

The Pertronix Ignitor does essentially the same thing as the original points and condenser, making and breaking the ground connection for the coil. It requires one additional wire to provide battery power to the electronic module. That wire is commonly connected to the power input side of the coil (original white wire connector). See attachment.

Pertronix ignition can be static timed in the same manner as points ignition. Set the timing mark on the crankshaft pulley to the desired static timing position. Connect a test light to the switched wire running from the coil to the distributor (the one that is not the power wire) and ground the test light. Turn ignition on. Rotate distributor body anti-clockwise until light is out (equal to points closed). Then turn distributor body slowly clockwise just until the light comes on (equal to points open). Lock it down and run it.

I stand corrected. Thanks Barney, don't remember where I read/heard (?) that pertronix could only be strobe timed.
