As the title, Replaced the regulator, battery ,regulator, alternator, took it to collapse but in very good condition,checked wiring continuity? with the engine ecu, wire the red power + 30 present, no cable to ground or short-circuit.
By disconnecting the connection to the three wires on the alternator charging stabilizes to 14 volts I don't know what else to do ,imagine that the ecu has problems thanks to all and good work, greetings.
