Locating the cause of an electrical fault can be a challenge even for the most experienced professional. I’m not referring to open circuits or even short circuits. These are relatively easy to find. In either case, the component, or load, won’t work. But the most...

How do you handle billing shop supplies?

When I first began writing service at an indie auto repair shop, one line item on the bill was “shop supplies.” We tacked on some percentage of the bill, capping at $19.88. Shows you how long ago that was! Customers would ask about it, and many were angry about the...
