I'VE got a coleman powermate 5500, i've got no output from the plugs. i've tried the circuit breakers. is there a fuse somewhere?

There is no fuse. Most common problems are loose connector from panel to gen set, worn brushes, faulty rectifier board or needs to be spiked (more serious reasons but lets not go there). Brushes and panel easy to check, remove cover to gen. and look at brushes for good contact to com. rings. Remove rectifier board from mount and look at capacitor for leaks or swelling. Replace as needed. Parts are available at jackssmallengine. com There are many ways to spike gen. as seen when you google the subject, however I just use a one amp 12v battery charger (or any small dc power supply 1/2 amp to 1 amp) and very quickly/split second contact brush connector while engine is running. Mind polarity, you must know which brush is positive. Usually on coleman the brush closest to bearing is positive. Spiking works immediately, if no joy, more serious problems exist. Dont worry, you cant break anything doing this, remember it is already broken. Post again if you have other question. Good luck
