My 5kw WB genny suddenly started putting out just 65 volts plus or minus 10 volts. Trouble shooting determined it was one of two capacitors that sit side by side. One good and one bad. Replaced them both and adjusted output to 60 hertz with a load of water heater, A/C, ice maker, and battery charger all running. Nice clean genny power now that looks just like shore power on the meter. Lasted 14 years and about 320 running hours. The genny has been a little funky this year but was was making enough power to run all the stuff we use until last week. Glad it failed when we got home from cruising instead of when we were still on vacation.
