And this is with the engine running? with no loads? So to make sure I got this clear. You attach the voltmeter, and reading is 12.6 volts start engine and voltage goes to 13.80 and with the engine running the voltage drops to 12 volts or below? Have you tried with engine running and then putting all the load you can on it and see what happens?
