How do I check if there is power at the fuse on a ’74 VW Beetle. Do I use a multimeter and if yes, what setting do I use.
I just rewired the voltage regulator, hooked everything back up and when I turn the key I get nothing.
I checked the battery, voltage regulator, wiring(continuity), conections and fuses.
Any help with this would be greatly appreciated.

If you’re just checking for power at that particular fuse, then hold the positive test terminal on an exposed end of the fuse terminal, or fuse itself (I assume these are glass ones). Negative can just be touched to any clean (unpainted) contact point on the frame assuming there is a proper ground. You put that lead directly on the negative terminal as well if you can’t find a decent one, or suspect a ground issue.
Use DC volt measurement on the meter, set for 20v range on most, whichever makes it the closest but past the 13 volt mark. Check if you have an autoranging multimeter as well, it will actually do this for you, you just have to set voltage type, dc/ac. Just need to pay attention to if it’s mV, or V when reading.

+1 The only thing I will add is that you can also use a test light to perform the same test. It’s sometimes quicker. You hook it up in the same way as you would the meter. Just connect the clamp to a good ground and when you touch power, it lights up. In fact, this might be helpful to you.
Also this.
