Question about Briggs & Stratton 11HP 6200W Es Generator
I have a Briggs & Stratton EXL8000 generator. I keep having to replace the brushes. The "furthest in" brush (black wire) is always broken and it appears that the casing for the brush melts. What could be the problem?
Sometimes it will work for a month. Other times a few days and even less.
I did find out that the inner slip ring was worn down. Still unknown why and the repair tech we took it to twice just replaced the brushes and never looked at the slip rings.
My solution, which has worked for over two months now (knock on wood) is as follows:
The slip ring on this unit can only be replaced by replacing the whole rotor assembly. I looked at the width of the brushes and the width of slip rings. The slip rings are twice as big as a brush. The solution was to move the brushes outward by one brush length. In order to do that, I had to turn the brush assembly around because of the extra plastic on the unit and space it out one brush length. Note: Still hook the wires as if the brush assembly was not turned around.
I used an old brush assembly and cut the two areas where the screws go through to make my spacers and it works perfectly.

Are you running something that has a high startup current? A well pump, air conditioner, air compressor, etc.
All of these things draw more than the rated power from your generator for a little while, then settle down and draw the regular rated power they have on the dataplate. This higher level of power is called the surge rating of the generator ( think the EXL8000 is something like 8250 watts for 30 seconds, check your manual) - if you regularly go over the surge rating you'll burn brushes, mess up slip rings, and potentialy kill a voltage regulator once in a while.
When we calculate how large a generator to use for an emergency backup system we add up all of the currents required by all of the things that have to run, then we calculate the maximum surge power for all the loads that have this requirement. We try and get a generator that will supply the "regular" load at 80% of it's rated capacity and still be able to handle the expected surge load. Sometimes we have to use a larger generator than needed for the regular load to get the surge load to be OK.
So you might need to trade up to the 10Kw Briggs to handle your load.
