Dash lights will not turn off!! 72 dart
Lets take a winch or plow that gets run while the engine is running. I've only seen the wired to the battery positive - some of the other guys maybe have seen some other arraignments but this is typical.
When the engine is running and the plow needs power, power is going to flow from the alternator which is producing at 14 Volts.
If the winch is pulling 30 amps and the battery is recharged, the ammeter will swing 3/4 of the way over to show 30 amps.
The alternator output is around 36 amps; 30 to the winch, and 6 to the ignition and field.
That's 36 amps going through that spade type connector. Turn the lights on, step on the brake and its more.
That's 30 amps through the ammeter and the spade connector and the 16 gage fusible link. And for more than a few seconds.
These are the situations that will cause damage.
A normal vehicle of this era doesn't draw 30 amps from the alternator except for brief periods when recharging and other equipment is running.
