the alternators have an aditional wire, called FR (fuel reduction i guess  ) this is driven by the PGM ECU. look at the pic...
i guess this wire is conected to ground or not in case of 12,5v and 14v, but this is only a guess, nobody could told me so far. so if u have a civic or an alternator, maybe u can find out for us.  |
or "Field" reduction?
