You can not check the flasher without putting a load on it, like two light bulbs. The load allows a little heating element inside the flasher to heat up, which then makes a piece of metal get hot and go "twaanggg" when it warps over and short circuits the heater element, causing it to cool down, and the piece of metal then contracts back to it's original position. The heater then does it again. That's how it turns the circuit to the bulbs on and off as that little piece of metal turns your lights on and off as it gets hot and cold.

The two fast blow fuses sit between the rear lights and the relay. The fuses under the hood sit between your battery and the relay. So, it's fused on both sides.

We will bench test your next relay on the kitchen table using a light bulb, some wire, and a battery. It will be easy to do.
