On the way there
1976 Instrument Panel
My FJ40 is currently being rewired by TrickyT and myself. We are basically trying to duplicate the layout/function of the factory system using a Kwik Wire harness.
The current plan is to keep the Ammeter, wired per the factory. The problem is, the alternator is being upgraded from 40 amps (stock) to a 60 amp unit out of an FJ60. The external voltage regulator will be eliminated.
Since the charging circuit runs through the Ammeter, can it handle the theoretical possibility of 60 amps coming out of the alternator (like charging a dead battery)? The meter only reads to plus and minus 30 amps.
I searched this until my eyes glazed over-but I believe the 1976 ammeter would be shunted internally, not externally like the 79 and up FJ40s.
