My LITTLE WONDER 110v runs for a while then blows fuse on 2000w Honda Gen. Have cleaned and greased moving inner assembly and cleaned brushes still NG.
When you say "blow a fuse" do you mean the Honda generator goes into
OVERLOAD mode, or does the push-button circuit breaker pop out?
Does the trimmer work okay on a regular extension cord?
Which Honda generator do you have, an EU2000i?
When this model goes into OVERLOAD, it's usually due to excessive heat/load on the circuit. If the breaker pops out, it's often due to a direct short or other external electrical malfunction.
Try switching the Eco-Throttle switch to OFF; this will force the generator to run at maximum power all the time, sometimes necessary for high-current loads that start/stop frequently (like an electric hedge trimmer).
