There is a black box in the fender wall locate just infront of my battery.
The print on the cover is badly faded. Could someone tell me what are these
fusible links for? Does it has anything to do with my alternator problem?
I am trying to solve my alternator charging problem. I am wondering if
there is a relay or fusible link etc..(not sure if it has one). There is a
sub-harness running form the back of my alternator to a connector that
position just in front of the battery. Where does it goes after? Through
the firewall to a relay?

Help!

No relay but there is a fusable link between the alt and the battery. You
can check for power at that subharness connector you mentioned. If the big
wire has power, the fusable link is fine. There are 2 other small wires,
one should be hot and the other is the signal for the idiot light that the
alternator grounds to turn the light on. 99% of the "alternator problems" I
see on these cars is from the use of aftermarket reman alternators. I've
yet to find -any- that are worth installing.
