I know I've posted a ton of questions about starters lately, but I've got some strange stuff happening now.
The Oldsmobile had a bad battery today, so had to pull my truck up the driveway with another truck to be able to bump start it (starter is still out). Then my buddy drove it down to our job site and parked it on a hill to be able to bump start it again (yeah, I know it's not that great for it). He drove it back to the house and said it died about halfway there on flat ground leaving no way to bump start it again. He looked under the truck and found a loose black wire hanging from somewhere near the starter. Reconnected it, starter started working again. He stopped to get gas, shut it down and was able to start it again. Then he drives somewhere else and finds it won't start. The "loose" wire is still connected and tight, but the starter will not go. Pulled it up another hill, start, brought it home. It continued to start just fine driving it around town a little bit later. The starter is actually working, but only intermittently. Should I just go ahead and replace the starter or is there something else I should check first seeing as the starter works just fine when it engages. No unusual rattling, grinding, etc.
Sorry for the long post, just trying to get to the bottom of this. Any ideas anyone?
