Either the fuse was old and weak, or something is drawing excessive current. Early OVP's have one fuse, later OVP's are a different design and have two fuses. They are NOT interchangeable.

Before I have to resort to GSXR's method (which I really don't have time for right now), are there known trouble areas/weak links where I should look first?

Sorry bud, what I described is the only method to pinpoint the problem. I supposed without a meter, you could pull one fuse at a time and see which one makes the Big Noisy Spark go away.

The pump has a timeout, so even if there is a leak, it will shut off after 30 seconds or so (unless the pump is bad, which is not a common failure).

The aux electric cooling fan on 1988-up models is controlled by the ACC pushubutton unit. It receives a signal from a temp sensor (not switch!) on the cylinder head, and above ~107°C or so, it triggers a relay which turns on the fan. Step one is to verify that the fan works at all - you can easily test this by shorting out the pigtails at the red or green switch at the AC drier behind the left headlight. If the fan doesn't turn on, check the fuse (external 30A strip fuse on driver's strut tower), then the relay, then the fan itself.
