With a $10 voltmeter, you can check to see if you are getting +12V at the input to the fuse box. If you are, then:
Closely check the fuses for the pink and yellow wires in the fuse box. Check and tighten (if necessary) the screws holding in the wires for those circuits.
If you aren't getting +12V at the entry to the fusebox, then listen carefully to the Univolt (the other end of the case which contains the fuse box). If it is humming, then it may be working. If it isn't, check that it is getting 120VAC at its input (using the same voltmeter).
Keep poking around until you find something unplugged, turned off, blown, or otherwise non-conductive.
If it's to be, it's up to me.
