I need to replace the output wire from the ‘negative’ post of the ammeter to the key switch. On the wiring diagram there should be 4 things (key switch, heater fan, turn signal, flashers) feeding off that ammeter post, but my ammeter only has one 10 gauge wire on that post (the left one, see attached pic). Do these other circuits split off from a terminal block somewhere? In particular, the wiring diagram makes it look like the 10 gauge wire from the voltage regulator to the negative terminal has another 10 gauge wire to the ignition switch that splits off before getting to the negative terminal of the ammeter.
Anyway, the goal here is to replace the wire that powers the ignition switch.
