My 12.5 Westerbeke shut down due to low oil pressure. I added oil and it cranked back up and ran like a top except there was no electrical output. I thought there might be a circuit breaker but I can't find one if there is one. Any thoughts before I start spending money on something that may not be broken?

What year and model? There is usually a fuse or circuit breaker for the excitation circuit somewhere in the gen box. There's an output breaker that also could be tripped
 
1988 Westerbeke 12.5 kw. The owners Manuel show a breaker next to an emergency shut off on the 8kw model but unless I am mistaken not on the 12.5. It is a bit tight in my ER so access is a challenge for normal size people.
 
When our Westerbeke 5.0 didn't generate voltage, and it's happened three time in the eight years we've had the boat, it was always due to a bad capacitor. In the 5.0 there are two of them which, of course, are buried in the innards of the generator.
