This gripe is similar to the one I have on my 88. The gripe has been coming on for a couple weeks, this weekend I was in a wrong gear going over the curb and stalled truck, and ended up with the A$$ end in the road and unable to restart. New Alternator (bench tested good when gripe began to come on), Batts load test good at 720 and 725 CCA on 650 CCA batts, new voltage regulator, system charging at 13.4 VDC, and starter about a year old. When trying to start vehicle now it will crank very slow with not enough to start Truck, "known good Batteries VDC 12.9 before crank 12 VDC after first try, Battery charge from 100 percent to 94 percent (unknown Amperage ) checked and clean cables and clamps. went under to check cable to starter, giggled wire from solenoid on starter (with key off) starter engaged (scared the crap outa me as the truck was in gear) charged batteries to no start. I think that the starter is bad simply because I kept loosing prime as there was an air leak in the fuel system, also IME, normally with dead/low batteries it would not have enough juice for the starter to engage into the fly wheel. What is the Opinion on this gripe?? Thanks
