My horn quit working the other day on my '92 Bonneville. Tonight I
hooked up my voltmeter to the plug that connects to the horn (two
wires), and I only get about half a volt when I press the horn button.
I can hear the relay clicking somewhere under the hood.

I'm guessing the next step is to find the relay and check the voltage
output there. But I was wondering if anyone had encountered this
problem before and had any advice.

All the horns I've dealt with previously had only one wire, and were
grounded through the chassis. Am I right in guessing I should have 12v
across the two connectors in the horn plug?

Thanks,

Yep, check the relay.
