SOURCE: Dayton SU936C generator starts but no power

Check brushes. Must be at least 1/2 " long. Check all connections. To flash field: use 12 volt battery neg. - goes to machine ground. Pos + goes to the pos+ brush, the one that's not grounded. Give it a couple seconds on the 12 volts.

SOURCE: can not excite generator

most generators you can polarize the brushs this is done by using a 12v. battery and a set of jumper cables hook to the battery and touch the brushs with the other ends it doesn't matter whicht side, but before you do all that check the connections at the brushs and see if they are loose or not making a good contact, i do hope that i was able to help you, thank you.

SOURCE: My generator is not producing

Simple way is to use a small battery charger (1 or 2 amp) and momentarily contact brushes (very quick swipe). You must watch polarity. Check your manual; generally the positive brush is the one closest to the bearing. Oftentimes problem is brushes have worn and are not contacting rings. Examine commutator rings for smooth surface. Remove diode board and check for leaking capacitor. If it is split open, burned or swollen replace as needed. Good luck

SOURCE: Manual needed for Dayton generator model 3w954.

try to Excite the generator.. TAke a 12 volt starting battery attach a wire lead to each post of the battery and plug the other ends of those leads into the 120v volt out receptacles of The generator while it is running FOR ONLY A SECOND OR TWO.. tHIS WILL NORMALLY EXCITE A GENERATOR THAT HAS LOST THE CAPABILITY TO MAKE IT OWN ELECTRICITY. Disconnect the 12v leads quickly so as not to over charge the battery. GOOD LUCK.

Why doesnt my Homelite HG3500 generator not produce power when running?


Try flashing the rotor it has lost it's resideual magnetism through sitting.
Disconnect the rotor field wires at the AVR or on the exciter/brushes. Note they are polaroty sensitive. Connect a 12V battery to F+ and F- (note polarity) and momentarilly power from the battery for a few seconds. DO NOT forget to disconnect the rotor/exciter field wires first or the voltage regulator will be damaged.

The gt5250 power back generator has stop producing


If it has sat, it may have lost it's rotor residual magnetism. Disconnect the rotor field wires at the AVR or on the exciter/brushes. Note they are polaroty sensitive. Connect a 12V battery to F+ and F- (note polarity) and momentarilly power from the battery for a few seconds. DO NOT forget to disconnect the rotor/exciter field wires first or the voltage regulator will be damaged. If it hasn't sat check voltage regulator, rotor resistance, and stator resistance, and for shorts to ground.

How do i excite a coleman sport 1850 generator?


This unit is capacitor excited, simply pull the terminals from the capacitor and apply 12vdc to the the wires for about 1 second. Then plug capacitor back in reassemble and run generator and check voltages. If the rotor magnetism has been restored and everything else is good you should be producing power now.

There is an alternative way to excite back end but it is a little more dangerous. It involves starting the unit and then applying 12 vdc to either of the 120v outlets for less than a second. This is the best way but it is more dangerous because once the back end is excited the outlet will now be putting out 120 vac. So if you leave your 12 vdc source connected too long you will back feed that source with 120vac. What we've learned to do is to have 2 wires coming out of the outlets with the tips exposed then we take our wires with the 12 vdc source and just brush them quickly against the 2 wires coming out of the outlet.

Hi I have an eagle power generator (E65DRE) and it will not generate power. All the coils and components are alright. Do I have to (excite) the generator after it has been sitting for a while? Has any one...


Yes, that's exactly the issue. You should run it once a month to avoid this. Generators can't sit for a while or they will loose the charge that excites the coils for producing power

Generator stopped producing electricity


if the generator has been sitting for a while you might have to excite the magnets to start producing power. plug in a reversible drill and with the generator running turn the drill in the reverse direction by hand while holding the trigger in the forward position.
