How do i tell if my trailer hitch is getting power?

carlton1983 asked:

I have a 2001 chevy blazer with both a flat and round plug in the back for pulling trailers. I have a boat with a trailer, but the lights don’t work. Fuses in truck are good, bulb is good, wiring on trailer is good. Is there an easy way to tell if the plugs on the truck are getting any power?

    I’d try a little portable multimeter with probes. See where the power is getting to and where it isn’t.
