So I was going to drive the truck to work today. I stepped on the starter and it engaged the flywheel as usual, but that was it; didn't turn over and didn't disengage. I thought maybe it was stuck and tried rocking the truck in low gear, but nothing, still engaged. Couldn't explore further as I had to get to work. Just exploring the archives here, and thought I'd put this out for advice - could it be as simple as the battery (about 6 years old)j. This is a 6 volt starter on a 12 volt system, though never ask much of it (starts easy). Thanks.
