Question about Briggs Stratton H7159 & Stratton® 5500, 10 HP Generator

1 Answer

No power output

Craftsman 5500W generator has no power output. Checked current at inner contacts and wires from generator and found no current. motor runs good. there is a circuit n=board inside the generator casing but didn't know how to check that. are there any diodes, fusitors, fuses or such that one can replace to try to get an output? any othe rideas?

Hi, check your exciter cap inside the control box as it probably is knackered, Replace it with a new one.
Or if the unit was severly overloaded the windings are probably fried.

Does a UST 5500w generator has a AVR. And if yes where is it located? Thanks for the help.


The contact number for parts and service is 1-866-797-2738.

The manual with parts is here: http://www.searspartsdirect.com/partsdirect/user-manuals/GG5500-UST-GENERATOR-manual
And it does not look like it has an AVR

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.

Hi, I recently purchased a used makita 6100r generator and when checking it out I discovered on my 30 amp 220 receptacles arent getting full power. I took out the receptacle and checked the wires in back...


You may be asking too much of the unit; the 5800 watts a which it is spec'd, may be a 'peak' power rating which may be 15-20% higher than its continuous rating. 30 Amps at 220 volts implies 6600 watts which is higher than even the peak power rating. I would expect the unit to produce ~4800 watts continuous or around 22 Amps.
Decided to check my statements and found this, which I quote:
Generator Volts AC (60Hz) 120/240 Max. Output Current 5800W-48.3A/24.2A Rated Output Current 4800W-40A/20A Volts DC (AMPS) 12 (8.3)

Just up graded from a homelite 4400 to a craftsman 5600 generator 5600 does not have enough output as did the 4400 why


Some manufacturers tend to fudge the numbers and throw around the 'peak' output power as continuous and it isn't. Peak (or surge) is the power a generator will handle as starting current (for example) for a motor and can be 120-140% of the actual continuous power.
Check you owner's manual, find the detailed specs which will normally contain the maximum continuous current rating. If it is listed separately for 120 and 220 (240) volts look for separate current ratings for each output.
By multiplying the current(s) times the output voltages you can find the total resistive output into a purely resistive load such as an electric heater.
For example: 120VAC X 20 A=2400 watts. If other outputs are available such as 220VAC, multiply its current rating: 10A. or 2200 watts Adding those two results 2400 2200=4600 watts will give you the rated power of a unit.
You can also recognize stupid power claims if the engine's horsepower is given. One (US) HP = ~746 watts. Since no generator is 100% efficient, its a fair rule of thumb to guesstimate the available electrical power at ~70% of the engine's rating (although, this is often also wildly optimistic). 10 HP X .7= ~746 X 7 or a bit over 5,000 watts.

No AC out put


After working on several of this style coleman generator,i have found that the lead wires in the windings that are soldered to where your brushes would contact tend to break.I don't know if it's a poor design or just a fluke,i would check to see if your getting continuity on the rotor and go from there.They seem to either "burn off" or just break.

I have a Powermate 5500W, Model PM0645500. The gas engine runs fine, but there is no power output. What can I do?


Sometimes you have to restore the magnetic field in the generator.
Look at the end of the generator....do you see a small + and - ?
You may have to take a cover off.
Take a small 9 volt battery and connect it to theses connections just for a moment.
With everything back together start her up and plug something in to the A/C output.
There is a 75% chance it will work fine now.

No output voltage at all


The generator needs to be 'flashed' to bring back the excitation for output. Is this something you can do? Let me know and I can help you...

Brand new Porter cable 5500w 10 hp generator - no output


Hi,
I wrote an answer that was for powermate generators, but it should help you too. I think you have a brushless generator, and rather than the plastic endbell I mention in the post you have a metal pie plate held on by 2 phillips head screws (yours is easier to get to)

Rate me if this helps, ask directly if it isn't enough,
Carl
