Sounds like time for a quick diagnostic. If you have done this already, my apologies for providing instructions that are obvious, however reporting the results here could help analyze the problem.

With the fuse panel hooked up and in the circuit, with the main breaker turned on (robot ready to go, but the OI not powered up), connect the ground lead of the voltmeter to the negative terminal of your battery.

1) Touch the positive lead to the positive terminal of your battery. What does it read? (should be about 12, give or take a volt)

2) Touch the positive lead to a metal connection on the positive side of the terminal block. It should read the same voltage as the battery.

3) Touch the positive lead to the positive terminal on the fuse panel. It should read the same voltage as the battery.

4) Now touch the positive lead to the output from the fuse panel where you connect your spikes/relays. (Make sure a breaker is inserted.) If you had the correct voltage in step 3, but not here, then the problem may lie in either the fuse panel itself, the breaker, or the connection of the breaker to the fuse panel. Try it with a different breaker. Try inserting the multimeter lead into the inside slot for the breaker. If that gives you a voltage, then the fuse panel itself is fine.

5) Connect the positive lead of the multimeter to the positive terminal on the battery. Touch the negative lead of the multimeter to the ground terminals on the fuse panel. You should read the same voltage as in the other tests.

Once again, my apologies if you have already gone through and done a test like this, however the chances of having blown a fuse panel are... while not zero... close to it.
