hello
the big red wire was the culprit, the starter was cranking slow.
about 5-6 inches from the positive terminal the big red wire was getting good voltage them when i probed closer to the battery terminal the voltage was much lower, i removed the black sheathing and seen a weak/bulging spot in big red wire.
i cut back a few inches past the bad spot and put a new batt terminal on.
now i get 13.50 at the battery and 13.9-14.0 volts at the alternator.
this is much better but not as good as my 95 940.
i may have to replace all the big red wires to the alt and starter.
the repair brought the voltage at the battery up about .7 to.8 of a volt
Art B gave me instructions to trace the problem by probing not just the connectors but the wire.
thanks
mike
