Generac 7500 EXL Generator

            I've owned the Generac 7500 EXL for a couple of yrs now. My first choice for a generator would
            have been a Honda but if you have priced the Honda's you understand. For my needs the Generac
            has done pretty well. All I use the generator for is backup power so it sits quietly covered most of
            the time. I live out in the country and power failures are pretty common (during hurricane Rita it ran
            for 32 hours straight).  As with most of the less expensive generators it is loud! I added a muffler shown
            below and this does help but most of the noise is from the engine itself and the generator, not the exhaust.
            It's also heavy at 250 lbs. the wheels / tires are not very heavy duty. I don't move mine around much
            so it's not a problem for me (solid tires would be nice).
            As for generating electricity the Generac has worked perfectly, runs very smooth.
            It also has a fully pressurized oil system with oil filter ( Fram PH 4967 )  I like and it has a large 7 gallon fuel
            tank ( I average about 10 hrs run time on a tank of gas ). Also has the auto idle and electric start that are
            both big pluses. It's no camping generator but it does make good electricity!
 
 


I added onto the original muffler by adding a 16" "Cherry Bomb".
This is a straight thru muffler and it does lower the exhaust noise to
a lower more pleasant tone  (the generator is still loud)
 
 


I welded a 1 1/2" coupling that I cut down over the outlet of the original muffler.
I then welded a 1 1/2" street el to a 90 degree elbow. The muffler slides onto
a piece of 1 1/2" pipe and is held with a 1/4" bolt. It's easy to unscrew and remove
everything if needed.
 
 
 
 

The off / on switch originally was where the white arrow is pointing.
I don't know why they put it over here. I don't know how many times
I tried to crank the generator and then remembering the switch was off.
I moved the off / on switch close to the start button as shown below.
( I did away with the original switch )
 
 
 


Now I can turn on the fuel and start the generator all from right here.
It's easier to see and no problem remembering to switch it to run.
The battery float charge port shown at the top is just a small
120 VAC / 12 VDC wall transformer ( trickle charger ) that can
stay plugged in all the time to keep the 12 volt generator battery
fully charged.
 
 

I also added an hour meter. I got this from E Bay for $10.

             I also purchased the Gen-Tran Home Generator Transfer Switch from CVF Supply Co.
            It's the easiest and safest way to run circuits in your home for the generator. It has a breaker
            arrangement  that prevents the generator from back feeding through the electrical utility.
            I also hard wired a generator connection outside my house where the generator sits.
            Just roll it outside and plug it in. If you don't use a power transfer switch or panel I would
            recommend just using extension cords from your generator.
            With a transfer panel all you have to do is plug in the generator and flip the utility breaker off
            and the generator breaker to on ( a metal bar between the utility breaker and generator prevent
            both from being on at the same time).
            After this all the circuits you have wired through the transfer panel can be ran with the generator.
            I have my lights, microwave, kitchen plugs, computer, TV,  refrigerator, freezer, window ac / heater
            wired in. Sure makes it easy and quick to hook up the generator.
