1999 Honda Accord EX 6 Cyl 3.0L

Preventive Maintenance

I have a good alternator and battery. When the car is off and we test the voltage, it puts out 12 v. On it puts 3? Why?

My car keeps dying. I replaced, the alternator, the battery, the terminals, and the alternator belt. But it's still dying, could it be a fuse?

Purpose. The alternator generates direct current for recharging the battery and for powering vehicle electrical loads.
A 12 volts device was shorted and created it a conflict to the alternator charging output. Do a process of elimination by unplug any 12 volts devices one by one and check the alternator output.
A 12 volts device could be the starter relay or the starter itself etc................

See this post to have the idea.
