My 87 Dak is acting like the battery is weak, but it has a Sears Diehard, less than a year old, and all the cells are full and check out good with a specific gravity tester. The voltage at the battery is 14.5 volts when idling and 13.25 volts after charging on a 10 amp charger. I cleaned both ends of the battery cable, at the starter, solenoid, engine ground and, of course, the battery. Now, after charging, the battery is good for maybe 4 or 5 starts! The only thing I can think of that might be at fault is the starter motor, but I never experienced a starter getting weak. They have always just burned out like a light bulb.
Any thoughts?
Thanks Jack
