more info needed.
Does the whirring stop, ie battery cant crank once bendix has engaged flywheel?
Does whirring continue, bendix not engaging?
Is whirring too slow, and not spinning fast enough to send bendix out?
You could have a little of both.
On the battery, measuring voltage right after charger disconnect is almost pointless. The battery will have excess surface charge. You need to let the battery rest with no load and measure voltage 24 hrs later. I forget the exact numbers, but 6.2 is not impressive. 6.35 is more like full charge. Little voltage differences matter, another reason specific gravity is a better test.
A very good tester is a specific gravity tester, looks like turkey baster. Not expensive, and gives accurate state of charge and battery health.
With an SG tester, you also can test all 3 cells, all should be close. One low cell indicates sick battery. Careful handling the electrolyte, its a strong acid. wash hands and rinse tester afterward. careful with errant drops.
Load test is good too.
