Can Bad pcb cause no charge from the alternator??

[Goinmxn]

I am having a problem with one of my 931a2s. The other day on the way home from a storm my voltage started creeping down like my alternator was not charging. (brand new alternator) I got home and the next day charged the batteries and it displayed symptoms of a bad pcb. No response to start switch, fan only on low position. Then I tapped on the pcb box and she came back to life. If the pcb fails does this interrupt the charge circuit??
Thanks

Yes it can.

Thanks for the reply. Looking at the tm you can trace the wiring on the charge circuit and see it. I replaced my run solenoid and all is good now. Man it is a pain to work in that little box....
