electrical headscratcher
i have a 94 safari awd vin w that recently developed an intermittent charging problem.dash meter drops from 14 to 12 volts, then slowly drops as battery drains, until van sputters and stalls as battery drains. then, alt will work again but intermittently.
checked battery cables, pos and neg,all are tight and clean. battery is 5 years old, but takes a full charge, starts van without hesitation. even so, i swapped out battery for my wife's brand new one, no difference. positive lead behind batt on firewall checked, no corrosion there, all fusible links good. thinking it could only be alternator i tried a new one, still intermittent charging. old alt back in, new one back to farm&barn. serpentine belt good tension, don't know what else to try. read through every forum re similar problem and none seem to correct my problem. help please
