Briggs & Stratton Briggs Stratton 7 kW Auto Standby Generator - Answered Questions & Fixed issues

sounds like problem with c board still a problem

The transfer switch is responsible for starting / stopping the generator. Check your auto - start circuit. It is 2 wires that go between the genset and ATS. They are generally normally open. When the genset is to shut down this circuit needs to change state.

You have a fuel delivery issue that can be dealt with by cleaning carb or replacing it. If you do replace carb has to be adjusted to the motor.(idle, mixture)

It shuts down because it's not making power. You are probably getting a failure to start error code. If it doesn't make power it doesn t know its running. Rotor has lost residual magnetism to start the voltage regulator. Replace the voltage regulator. The new one is designed to overcome this.

rectifier bad.

Can you manually adjust the voltage on the generator without load?? If you have 120/240 60hz output on it and you are not overloading the unit (amperage), then it may be as simple as adjusting whats called your gain setting for your voltage regulator. Obviously you are seeing what happens when it is set too low. Trying raising that setting until it becomes unstable then back it off. Unstable meaning voltage starts jumping all over.

Check your output voltage and frequency on the generator when you are connected to it.

Hi and welcome to FixYa, I am Kelly.

Spend some time reading this manual after you download it:
http://www.guardiangenerators.com/PublicPDFs/0F7698.pdf

This is how the manual page 99 says you should set the weekly exersise cycle:
(this should be the same for your generator)

SETTING WEEKLY EXERCISE CYCLE

The generator will start and exercise once every

seven (7) days, on a day and at a time of day selected

by the installer or operator. The unit will run for

approximately 13-15 minutes during this "exercise"

cycle, and will then shut down. Transfer of electrical

loads to the "standby" power source will not occur

during the exercise.

A switch located on the generator control console permits

the day and time of exercise to be selected. To

select the day and time of day for the system to exercise,

proceed as follows:

• Place the AUTO-OFF-MANUAL switch to its OFF

position.

• Hold the set exercise time switch at its ON position

for about five (5) seconds.

• After five seconds, release the set exercise time

switch to its OFF position. Wait 30 seconds, then

place the AUTO-OFF-MANUAL switch at AUTO.

The generator will exercise every seven (7) days at

the selected time.

NOTE: Failure to wait 30 seconds before placing

the AUTO-OFF-MANUAL switch to AUTO may

result in engine cranking and startup. If the

engine does crank and start, it will shut-down
automatically within about two (2) minutes

If it still does not work... Check the Utility Power line transformer resistances in the transfer switch. Also check the terminal board in the transfer switch for any corrosion or signs of heat.

All Terminals connections N1, N2, T1, T2, E1, & E2 should be tight and clean.

If you need more assistance just respond here and I will help you.

Electric clocks use synchronized motors that run on 60 Hz AC. The power company provides AC power with a precisely regulated frequency of 60 Hz. That means that the voltage jumps back and forth (positive to negative) 60 times per second. Your generator would do the same thing if it could run at precisely 3600 rpm (that's rev's per minute) - but it can't, because the engine is not that precisely controlled. In your case it tends to run (on average) a little fast. I hope you found this helpful. By the way, in Europe 50 Hz is the norm. If you run a clock designed for 50 Hz on 60 Hz power, it will run 20% too fast! Al K

It sounds like the starter contacter is shot. I do not remember if the starter on this unit has a separate contacter or it is built onto the starter. I thought your starter might be shot, but you mentioned that you have full voltage going into the contacter and low coming out. Now, carefully, you could see if the starter is good by bypassing the contacter. Do this carefully. Take a battery jumper cable and connect one end to the starter cable on the contacter and touch the other to the battery end of the contacter. This will cause some sparks, but it will tell you if the starter turns or not.

There are Three things a Motor needs to work, Fuel, Spark, Air. So you simply check each step, If you have Fuel, and you are sure it's getting to carburettor, then, First check, spark plug, (Replace is best), spark plug leads, and Ends. See if there is a "Spark" when the Motor is turned over. IF there is a good spark, OK, if NOT find out why, check, coil, check, points/Electronic ignition. Alternator. IF all good there,then Check, carburettor, Needle valve, Jet, float bowl, float and valve, check mixture. www.repairfaq.org/samnew/lmfaq.htm www.briggsandstratton.com/maint_repair/ www4.briggsandstratton.com/display/router.asp?DocID.

Those links above should help you find and fix.

off you ask them they have it. ask maker of engine, the tool make would not. (sump) service manual is the name. ask maker https://www.briggsandstratton.com/na/en_us/support/manuals/results.html

This appears to be something for a Briggs and Stratton engine, so I moved it from the Microwave Ovens category. 'Make model (what is is)' in all questions please and in this case (what it is off) as well :>D Call Jack's Small engines. If he doesn't have it, or know a replacement, no one does! https://www.jackssmallengines.com/jacks-parts-lookup/manufacturer/briggs-stratton/briggs-stratton-engine/400000-699999-series/407600-to-407699/407677-0258-e1 images of Regulators. Look similar? https://www.google.com/search?q=voltage+regulator+407677-0258-E1 ..

Maybe you can check on operation manual or ask your supplier. If you need to have diesel generator set for power generation, please refer to a company website: www.dieselgeneratortech.com. They have doing genset for more than 43 years.

Doesn't look like anyone came close to answering this question correctly.While I realise I am answering a VERY old post, a correct answer may help others that come here in the future who are experiencing the same problem.The issue is with the starter clutch. It screws onto the crankshaft and works like a ratchet wrench. It allows the crankshaft to turn freely one way but "catches" if turned the oher. Most people don't maintain them properly so it gets rusty inside and the bearings don't move like they are supposed to. Hence the clutch doesn't lock.It's usually a pretty simple fix. Remove the flywheel cover, secure the flywheel so it doesn't turn then use a rubber mallet and a drift to loosen the clutch. It has normal threads so it turns counter clockwise. It should come loose pretty easily. Once off, look at the front of the clutch. There is a cover which is just pressed on. You should be able to get it loose with a hammer and small flat head screwdriver. Carefull you don't loose the bearings (there are 6) which are pretty large. Clean the whole thing out, removing any rust and debris.Then spray the inside with some lite machine oil (don't use grease or any other thick lubricant).The shaft should have a piece of felt in the center of it. This should also be soaked with machine oil. To reassemble; place the washer and shaft back into the housing, then place a bearing in each "hole". Give it another shot of machine oil and press the cap back on.Put it back on the engine and replace the cover. You should now have a workng starter. There is a small hole in the front of the clutch. You should periodicaly squirt some oil into it to keep the clutch lubricated.

hi I think that the problem you have is not with the coil. let me explain : when there is the need to stop the engine simply we push a button or use a lever in both cases what it simply does the coil is grounded to earth this stops the spark supply to the spark plugs . find the cable which connect from the switch on to the coil because this cable intermits to short to earth stopping the spark going to the spark plug ( replace cable this will prevent the engine to stopping )

The engine is running too lean.

check for excessive oil in the sump the hose allows compression build up in the sump to escape to the air cleaner so the valve (????) is operational

If the engine is locked, it could be any one of several things. Most are rather expensive, like: seized due to no oil; broken rod; bad valve, etc. An engine mechanic is going to have to troubleshoot it for you.
