I am repairing an older -6, and am starting in the middle of the project. I am trying to wire up the UMA Electronic Tach. It gets its signal (apparently) from the P-Lead terminal(s). So when the mag check is done, only the mag that is firing produces a signal? However, when checking the mags, only the right one is turned off?? Does anyone know how the Mags, Switch, and Tach are wired?
Thx. RC
