If you didn't know the fuse box will unlatch and drop to a vertical position. There are two latches on either side of it. Squeeze them to the middle, push up slightly on the fuse box to take the tension off and you should then be able to pull it down.
|Edit> Meter blows fuses? You likely set meter probes to use Amp shunt. replug the meter...|
What he means by this is either
1 - Your test probes are not in the right holes - The black should be in the COM (Common) hole and the red should be in the V or V-Ω hole. It must NOT be in any hole that looks something like 10A
2 - Your knob needs to NOT be pointing to any measurement that ends in A.
Even turning the knob quickly past the settings that end in A can cause things to blow. Many meters have a fuse inside them that can blow also, so if your meter now acts dead or only reads 0 get the screwdriver out and check the fuse.
I really like using a 12v trouble light when checking for power and checking fuses. It puts a small load on the system which is good when checking for power, you don't have to look directly at the light to know if it's on or not, you won't ever get messed up because it is showing mV instead of V, you don't have to worry about setting the knob correctly or putting the leads in the wrong holes.
A wonderful way to check fuses. - Turn on the circuit in question - Now take your test light, and connect the ground clip to metal. Touch the tip of the light to one of the test spots on the back of one of the fuses that always has power. The light should light. Now TURN ON whatever it is that is not working. Assuming it does, now touch the tip to all the other fuse test spots. If the light lights on both, the fuse is good. If the light lights on only one, the fuse is bad. If the light lights on neither, then there is no power to the circuit (ie your lights are turned off and you are checking the fuse for the dimmer switch.
Note - In the above procedure you do NOT have to pull the fuses, unless one of them tests bad.
Can't get easier than that can you?
