While sitting at home playing Call of Duty (BRO) my friend ended up being stuck an hour from home because her 4Runner wouldn't start. Instead of calling me immediately like she should have, she had some of her coworkers (doctors) attempt to jump her. That was unfruitful, and it was decided that she needed a new starter.
Two hours later, she posts on Facebook that she's having issues. I head out her way and meet her husband there, who had just arrived. A couple quick glances and we spot the problem; the positive terminal has a good bit of corrosion. We clean it off, give her a quick jump and tell her that her doctor friends owe us beers.
Don't trust a doctor to jump your car.
