How to troubleshoot blackmax pm0497002 electric generator

The generator worked fine during last power outage about 6 months ago. This time motor runs fine but no power out of any of the 120v outlets or the 240v outlets. I pushed reset breaker buttons to no avail.

SOURCE: Generator runs, but does not generate electricity

Reset / tickled? There are resistors and diodes in the end of the alternators rotor (the bit in the middle that spins) If these look ok visually then change the capacitor which is a barrel shaped object usually with 4 prongs on the end. Without a capacitor the genset will not produce a voltage.

Yes, there must be a protection device on the unit somewhere. It should be indicated in the owners manual. It may be on the box the outlets are in, or built into the cover of the generation unit.

SOURCE: No electric power generated from my Coleman Powermate Maxa 5000W.

the gensets on coleman generators are definately nothing to brag about but i would start by checking the windings and make sure the brushes have a clean armature to ride on

SOURCE: Coleman/Honda Generator - No Electricity

take a look at the fuse...if it seemed burnt then replace it.
if not.
then check the breaker...try connectting your voltmeter directly to the wire that goes into the breaker(directly to the +) and the other side to the regular (-).
if it read 220 volts then the breaker is down...so replace it...or you can use the outlet directly.
however if it didn't read any voltage,
then you should check the brushes...they are right next to the AVR module...(the two wires that come out of the AVR are connected to the brushes)
if the brushes are shattered or if there is no connection between each brush and it's connector then replace the brushes..
but if they seemed fine.then your problem is with the wires...trace every wire and check for continuity.
the problem has to be one of the things i mentioned.

Probably its similar to the wiring on page 31 of this manual (pdf page 28) of this manual, reference NGK-7000HE: http://www.electricgeneratorsdirect.com/manuals/NGK%20Generator%20Honda%20engine.pdf

Maytag MED5700TQ occasionally completely shuts down during cool down mode


Sure!
You may have a bad timer, that is turning off the electricity to the motor while the heater is still energized.

Long time ago, dryers had about 3 "automatic shut-off's" two on the heating element, and one on the motor.
Because of the lint that comes with drying clothes, fire is always a danger.
Today, the "thermostat shut-off's" are up to 5, 6, or 7 on some models!
Sounds like your dryer is getting hot enough to trip one of these. When the whole machine cools down, the thermostat resets, and the machine starts again.'
I had a dryer do the same thing. The problem with that one was nothing more than dust and lint in the motor, and all I had to do was vacuum out or blow out the motor about once or twice a year.
Be blessed

Make sure the sparkplug is clean and gapped. Unloosen the float bowl slightly and drain about a half cup of gas out of the bowl. It is possible a little condensation got in to the fuel. Tighten the bowl nut slightly and try to start the generator.

My timer has been working fine for the last 6 years. I replaced the fixtures about a month ago and a couple of days ago I noticed the timer was about two hours off...Does anyone know what the problem...


John, This came up under chain saws, but I assume this is an electrical timer and the fixtures you replaced were the light fixtures that this timer controlled. Maybe the timer is about 2 hours behind and the fixtures took about 2 hours to replace, during which time the power was off and the timer did not run. Sorry if this seems too simple and obvious and you already thought of it, but you haven't given me much to go on.

Installed a generac 20kw about a year ago, ran fine untill 2 days ago. During a utility outage, generator ran for about 30 minutes and then stopped producing power while still running. All mains were still...


With the engine off, check the exciter brushes and slip rings which supply magnetic power for the alternator winding in the stator. Also, check the motor-to-alternator mechanical coupling. Check the breakers for tripping. To service beyond this point requires a schematic of the alternator, a voltmeter, plus knowledge of what the schematic is telling you. Good luck!

My son purchased this generator about a year and half ago and has used it very little. during a power outage we got it out and used it for a day and the circut board went out. shouldnt it have lasted...


That sux! Thats NOT acceptable in any way... Take it back and demand it gets repaired.. With devices such as this it is not the simple passing of time that ages it, but the actual POWER ON time... & Yes if Overloaded it should simply have "Tripped" a breaker or the like.

Motor starts, but no electricity...NEW


Make sure the motor is turning the alternator--check the coupling device between them. Is there a circuit breaker on the alternator--reset it? Plug a lamp or something into a socket. If it works, the voltmeter may be in trouble. If still nothing, an inspection of the interior of the alternator is required. If the engine is off, there is no danger of getting shocked. Look for broken wiring anywhere.

Generator won't start


Some of the generator has a control or tripping device like over speed, over voltage, overload or overcurrent or other trip device, try to find & reset it.

Coleman Powermate only puts out 110V


If you haven't seen it yet, here is a page that may help with a manual or parts list.

This problem sounds kind of bad, generators don't do well when the engine stops under load.
Start by checking the circuit breakers in the distribution box (outlet panel) - you need ot do this with an ohm meter. After that check the power windings of the stator with the ohm meter, be sure to check between the 2 windings (should be open), and from each one to ground with the winding isolated.
Whining, a burning varnish smell, and breakers that trip all the time are indicators of long term overload problems. This could happen if you had most of the load on one winding for a significant amount of time, or if the one winding mostly powered motor-like loads with high startup currents.

You may want to look at this answer I posted some time ago.

Regards,
Carl

Coleman 6200 won't work


Hi Judy,
Generators DO last a good long time for the money, but they have to be both used and maintained in order to keep working properly. What has most likely happened is that you didn't use the generator at all for a year, after it sat on your dealers shelf for a few months not being used, and so the tiny bit of magnetism it uses to "kickstart" the process of making electricity has worn down. The good news is that this is easy for a generator shop to repair, no parts involved and the minimum labor that they charge. They need to do something called flashing the field of the generator. What they can't do is get Coleman to pay for it since they aren't around anymore, go ahead try the 800 number (waits patiently).

Be nice to the poor generator techs at the shop.
