starter problems causing high voltage?

[aaronh33]

Kinda new on here and have a few questions. First off i have a 1986 k20 with a 350 in it. So the other day my starter decided to stop working. So I went to the parts store and bought another stock replacement. Replaced the new one the same way the old one was and when I went to start the truck I noticed that the gauge was reading 16-17 volts. It was running at 13-14 volts before. So I found that one of the wires was kind of pinched I straightened it and tried to start it again and noticed that the gauge read about 14-15 volts. Seemed kinda high to me, but thought it would be OK. Thought there might be some drag on the starter so i tried changing the shims around to see if it would get any better, it did not. Took it for a short drive to see how it would run, shut it off a few times to make sure it would start again and it worked fine. Now this morning I went to start it and the starter engages and turns but the motor won't start. Any ideas as to what could cause this? Did the high voltage cause some unseen problems? Any help is appreciated.
