I have a 1993 Astro Van AWD 4.3 vin W.
Over the past few weeks my voltage gauge has been dropping
after the van has warmed up. A few times it dropped enough
to make the battery light come on. I checked my connections
and switched the battery with a newer one from my truck but
nothing changed. So I had my alternator rebuilt. So far the
battery light hasn't came on but the needle still drops.
I checked the voltage with a meter at the battery.
Under load at idle it would drop as low as 12.4v. While the
van was running I checked the fusible links at the harness
behind the battery and noticed that the black one was very
Does anyone know what the black fusible link connects
to and can this cause a voltage drop?
