Question about Electrical Supplies

Open Question

I have a generac 15,000 watt generator. Gp15000e. At first right before the storm, it wasn't getting spark intermittently and sometimes it would start. Long story short, a guy came out and changed the circuit board inside and it had spark but still didn't run. The owner of the company came and disconnected fuel switch and now it runs. But now there is no AC output and there was before the board was changed and it runs at wide open throttle when choke is in. I have no idea what's wrong and the guy won't come out for a few days.

SOURCE: Coleman Powermate 6250 only runs with choke closed/air restricted

A call to Elliott Small Engine solved my problem - Oil Guard. I had checked the oil and it was just a little low but seemed well within the normal range. I was told to add more, bringing it just over the Full mark. It seems that the low oil protection system is very sensitive and shuts down the engine even when the oil is withing 1/8" of the mark. I added about 2-3 oz of oil and no more problems

SOURCE: Generac Guardian 15kW Generator

That sounds just about right, if the relay contacts get welded together it sometimes takes out the driver on the printed circuit board. As you found out, 12vdc from 23 to 194 makes the transfer switch move to the Generator position, relay not energized makes the ATS move to the Normal position.

You can make a nice test function by installing a 10 amp contact switch in series with either the N1 or N2 terminals. When the switch is open the generator thinks the Normal power has failed.

Regards,
Carl

SOURCE: My troy-Bilt 5550 watt generator will not start

First drain the fuel bowl. Any old fuel in there will keep it from starting. Fuel stabilizer is not what it's it cracked up to be. I've worked for 6yrs at a rental yard and had no luck with any fuel stabilizer, the fuel still went bad. If after you drain the fuel bowl it still will not start, you will need to clean the carb. Remove the carb and spray carb cleaner through all the accessible passages. If this does not do it, you will need to replace the carb. For long term storage I highly recommend draining all the fuel and filling just the carb with fuel stabilizer to keep gaskets moist. Then drain the carb when you take it out of storage.

SOURCE: I have a Generac portable generator 5000 watts, won't start!

I am assuming the generator worked fine before the oil change. Now that you have done the oil change the genset does not start. These generators have a safety switch, which is basically an oil pressure switch that keeps the engine from running when there is not enough oil in the engine. Make sure that there is enough oil and if there is, look for a wire that runs along side of the engine to a round component. disconnect that wire and try starting. If it does not start then try to ground out the wire to the engine block. If this does not work, then there is other engine problems.

What's the mag or coiul on a generac 6500 generator 13 hp


The "mag" is a magneto and it generates the high voltage pulse to fire the spark plug. The "coil" is about the same thing but it uses a set of points or an electronic ignition to control when the spark is delivered.

The current starter battery is not recharging. I would like to know if there is a problem with the alternator or battery charging mechanism. If so, is there a replacement part available ??


Hi Frank,

Have you charged the battery and see if it holds a charge? If it does, then it's probably your alternator.

I hope this helps. If it does, I'd appreciate your vote. Thanks,

I have a Generac XL4000. It rill start but not run right.


If the area you live in has alcohol added to their unleaded gas, then you will probably need to rekit the carbuerator. Also check the spark arrestor for plugging up. Try to find a non alcohol, off road unleaded gas for your generator.

I have a Generac 15000 watt portable generator. It cranks great, but will not start. The plugs are wet, doesn't seem to be getting any spark. Have replaced plugs, any suggestion.


I have solved the flooding problem . unfortanetly you must remove the carb to fix it. once you remove the carb you need to remove the fuel bowl. In the bottem of the fuel bowl there is a electronic seloniod that controols the amount of fule going to combustion. this aria had varnish and gunk built up around the plunger of the selonoid, long story short clean this out with carb and chook cleaner and put it back together. start her up and she will run like a champ.
