Generac 5500exl- has worked great and then suddenly shut off and now
starts and runs fine but with only 5volts power. The brushes and diodes
are fine. Any ideas what to do and where to get the parts? Thanks.
It may have a small circuit breaker on the field winding. On the larger
Generac units I've serviced, there is a small breaker for the field
winding inside the control panel. The units also had a voltage regulator
module in there too with a red LED indicator that lights when it's

It recently worked? It didnt sit for months? Did you get it new and
its never had the field flashed? I read sometimes a field can need
reflashing but if it recently worked probably not. Try pushing the
brushes in tighter.
A Field Flash might be exactly what it needs. It's easy to do and not
dangerous IFF you follow the rules for it, which I won't take responsibility
for here. See the mfg's web site or go ask a repair center. Only takes a few
minutes if you know what you're doing.
Recently tripped over a bunch of verbage on this topic.
If the field needs flashing and your generator is an older
one with the output connected to the front panel, no voltage
regulators or inverters or ....in between,
people suggest hooking up an electric drill, pulling the trigger
and turning the shaft as fast as you can in both directions.
If it works, the drill will start up under generator power.
So wear gloves.

i had a generac do that 5 volt thing, there was a plastic box with all
the parts potted in by some goo, no schematic available. after it went
bad twice at 75 bucks each a buddy modified it. the box automatically
engaged the start charging circuit once the engine got up to speed.
now i start it , then push a very heavy duty switch that engages the
start generating circuit..
engine slows let go of switch.
