Ignore the aux, n or s terminals on the alternator. http://www.aeroelectric.com/Reference_Docs/Alternator_Data/Legacy_EM_Regulator_(Ford).pdf This is because the solid state replacement for the Ford E-M regulator is NOT a strictly functional replacement. The "S" terminal does not behave in the same manner as it did on the E-M products.

It does this by controlling the field through the p rotective breaker, which, in your case, seems to be breaking. The increased voltage you temporarily saw might be perfectly normal if your v oltage regulator was in its death throes and not regulating properly after w hich it gave up the ghost and would only blow the field breaker All of this is to say that your voltage regulator may be the culprit not the alternator. Keep us apprised about this breaking news Rich Sent from my iPhone > On Nov 25, 2018, at 2:15 PM, Ron Burnett wrote: > > Follow up on field Cb: > > Now the 5 amp Field CB blew after take off yesterday and could not be rese t.

PlanePower uses the stock, INTERNAL votlage regulator in their automotive->airplane conversions. So in this case, the whole alternator assembly needs to be returned for evaluation. In this instance, it appears that the PlanePower added, crowbar ov management system was doing its job.
