Another question on the same subject. Looking at Mattax's 1st (simplified) diagram,
Shouldn't the alternator battery wire/circuit also be fused ??
Lets say the car is driving down the road and there is a short that blows the fusible link.
That will isolate the battery, but the alternator will continue to back feed the short as long as the engine stays running. That in turn would cause a meltdown, Correct ?? or am I missing something
as I already have told previously. The only power source able to feed a short is the battery. If the fuse link blows the current coming from batt on a short, once fuse blows if short still goes on, the engine will stall. Any short will take all the power, so the regulator won't get enough power to feed the alternator and keep the system going.
you can try it easily. Crank up the engine, disconect the bat and make a short anywhere... try it between alt stud and body for easier experiment and safer for the rest of the wiring. Engine will stall and with batt disconected, fuse link won't blow because there is not a source there to blow it up, but engine will stall
