No electric output, how do I diagnose, capacitor, proper winding check etc.


Have you tried flashing your generator? Sometimes the magnets in the generator loose their polarity. Google and YouTube "flashing a generator"
HFLASHING the GEN

Sometimes the magnets lose their polarity. This worked on my brothers $1200 gen. Its worth a try. Good luck!
Check all wires/connections first, Then try this-
(Remove spark plug wire first!)
To flash the field on a small home use generator, get an ext. cord & cut off the female end of it & strip the wires & connect the wires to a 12 volt car or lawn tractor battery, & plug the male end of the cord, into the 120 A.C. side of the generator.

Make SURE that the black wire which is POS/HOT on an A.C. cord, gets connected to the RED/POS. side of the auto battery, & the white wire on A.C. cord gets connected to the BLK./NEG. side of the battery. If the ext. cord wires are not black & white, then the smaller prong of the plug is the POS./HOT

Plug the other end of the ext. cord into the generators 120 volt side (**remove spark plug wire**) & pull the starter cord 4-5 times, then remove the ext. cord, reconnect the spark plug wire, start the unit & plug something of 120 A.C. volts in to see if it works. Then let it run for about a half hour with 2 - 150 watt lights to help re-generate the unit.

Only has 120 volts,can not get 240volts


the generator consists of 2 120volt windings that run in parallel for 120 volts and in series for 240, check the change over switch make sure a wire hasn't fallen off, if you have a multi meter check both coils have the same resistance

Want to add 240volt outlet to generator


You CANNOT do this, USA 240V is derived from a poly phase scenario, IE 120V line to neautral and 240V line to line, UK 240V is derived from 1 line to neutral it will not work unless you power a transformer

Can I make 2 plug in sockets from one in a 240 volt circuit


There should be NO problem in actually "Adding: another :Outlet" have you thought of a 20 - 25 Amp Power Strip, Multiway Socket, As long as you DO NOT exceed the Amperage/Wattage of the "Supply" The generator, 5000W, there will be no trouble. You MUST ensure however that this is so.
5000 Watts is 21 Amps, Watts = Amps X Volts. IE: 21Amps x 240 Volts = 5000Watts +/- 10%. So the TOTAL Amps drawn by the SUM of all the things connected must be LOWER than,say 20 AMPS.

Flash field on generator


Yes, polarity does matter. If you remove the front cover on the generator end you will see where the rings and brushes are located. The closest to you is positive and the ring that is towards the engine is negative. Trace those wires up into the control box and flash the genset there. The six volt battery is fine. I preferr 9 or 12 volt battery, so that I can produce a larger AC voltage.

Three year old coleman 5000/6250 generator. High


Your RPM's are too high. There is no voltage regulator in coleman generators (generator is actually made by generac) and is 100% dependent on engine speed. There is a screw under the tank when your looking in from the recoil side. It controls the governor arm. Screw it in and it incresses the rpm, out decrease. Plug something in that draws a decent load while setting the rpms since you want it to put out 120 and 240 underload. Your idle voltage does not matter.

Coleman 7000w gen. I have 120 on only one side of my 240 plug. I disconnected wire assembly from control box.. Could get 120 out of various combinations of the 4 wires but never 240. Should I be able to?...


Hi,
At the wire assembly there should be 2 white and 2 black wires, a white and a black are the ends of one 110v winding. With the 2 white wires connected together you should get 240 from the black wires. This sounds like it is a problem with one of the circuit breakers in the 240v outlet in the control box, check them with an ohm meter.

Regards,
Carl

Coleman 6250 gen


Assuming there is nothing wrong with the generator, I'm not sure what the Amp rating on a 1 hp compressor is, but starting currents can be 5 or more times the rated current, especially for starting heavy loads like compressors. While the motor only needs it for a short time, if it doesn't get it, it ain't gonna start. If you really need to run this compressor off this generator, one possible solution is to see if the compressor motor has connections inside to wire it for 240 volt operation. I realize in theory you should have available the same full power rating from the generator at 120 v and 240 v. However, many times a motor will still start more easily on 240 than 120, for the same reason that automobile starters went from 6 volt to 12 volt. If you do change the voltage to 240, BE SURE TO CHANGE THE POWER CORD AND PLUG ON THE COMPRESSOR!!!

As a side note, I have one of these generators I purchased as "refurbished", and it is flakey. It works, mostly, but not exactly right. I'm working on it. So anything COULD be wrong.
