Mickey....,
My standard recommendation is to use a separate stand alone battery when first firing up the engine after an ignition system installation. PMA's can be weird in how the voltage regulator works or doesn't work, including producing a very high voltage (>20V) or they can actually cause the battery voltage to drop due a malfunction that essentially pulls the +12 to ground. So, get the engine running first with the PAMCO and a separate battery before you troubleshoot what happened to the battery you have, or remove that battery and charge it overnight then use it to power the ignition only. Disconnect the PMA and regulator for the initial start. This advice is good for other ignition systems as well. It's not just the PAMCO, although I have had my share of accusations, including one person who claimed that his brakes did not work properly after installing the PAMCO.
I told him that real men don't need brakes, and I never heard from him again!
(Fortunately for me...real men DO need ignition systems...
)
