An OBD scanner
A decent flashlight
A mini screwdriver set
A multimeter
An outlet polarity tester
These immediately come to mind.
If you are not comfortable working with electricity, you shouldn't be working with electricity. Following, a multimeter and an outlet polarity tester are not really things normal people should have.
Ok for the rest.
I hired an electrician to rewire an outlet under my sink so that the switch above the sink can control only one of the two plugs. When he was done, I used the outlet tester and found that he hadn't properly connected the ground wire. I wasn't planning on connecting an appliance that needed grounding, but I think every outlet in the house should be grounded anyways as a matter of course. Got him to fix it before he left. That $9 I spent 7 years ago paid off as far as I'm concerned.
