You also have an extension cord which will drop voltage for every foot you have between load and generator. use at least a 12 gauge or heavier heavy duty cord no more than 25' long to run any demanding loads. Remote work sites that use such a low output generator are good for charging batteries, lighting, small electrical loads like drills or small circular saws. less than 7.5 inches.
A powermate 1500 is only surge, its more like 1200 continuous. Which means 10 amps output at 120 volts. Volts times amps equals watts. Now here is the rub. There are many factors that influence output. You are not going to have 120 volts at 10 amps. you will be lucky to have 100 volts like you have. Electric motors use twice the rated wattage. Lights, chargers, other such loads can survive on 2 pole cheap gen sets. Fluroescent lights may flicker due to number of poles in generator and harmonics.
Sounds to me like some sort of carb/voltage regulation issue. Most generators have a linkage to open the throttle when they sense a load on the alternator. Doesn' t sound like yours is kicking in.
it might have a loose shaft on the generator or its an inverter generator with a bad board, or it may have a bad capacitor if it has one, or you may just be going over the load limit.
seems like the brushes like one person said below or maybe even the windings im not sure somethings worn out and is not producing 1500 watts in the generator
It's working fine. The voltage drop is normal, considering it being a smaller unit. The governor could be bumped a little higher though, so it's at least a constant 110 under load. Won't matter if only used for power tools though.
would recommend taking a look at the governor. see if there is any springs missing. PLus if u can find the voltage screw thing where you turn it and it increase the rpm and voltage you should try and adjust that.
The same thing happened to me my UK generator should produce 230v at 50Hz and it was at like 190v so what i did is i got a P3 Kill a watt (multimeter would work fine) and plugged in a 500 watt floodlight i looked at the voltage reading and turned the screw clockwise until it read 230v - 49.6Hz and it worked a charm.
The muffler is solid, and this is actually a pretty quiet machine. Now, If it were brushes, wouldn't it put out the wrong voltage all the time? I really would like to get this generator running well.
@carrabec99 I find there is nothing wrong with the generator or brushes. Use an analog voltmeter, you will find the voltage reading is stable. Some digital multimeters (especially cheap ones) can give erroneous readings caused by harmonics produced by the generator. I have had the same problem with mine, a 4000 watt unit. I found it was the cheap digital meter was the problem. I got a better meter and it checks out good.
I live in Pakistan & i bought 10hp power mate generator.This generator is very brilliant it runs 1.5 ton AC.Love power mate hope it works for longtime.
Get a bigger generator. Specs on generators these days deceptive. I would go at least double the rating of your biggest starting load. No such thing as too big with a gas generator. Use the little one for lighting.
its fine dnt worry as long as it runs what you plug into it and doesnt break the appliance and doenst start shooting sparks, and rember it is old i say get a bigger muffler and blast Styx
I think what you are seeing is normal. The governor is compensating for the load. However the governor is set a bit too low to maintain the proper voltage. I have had generators come to me set incorrectly at the factory. Normally I plug in something with a light load as a ballast, then set the governor so that the generator produces around 125V. This keeps the voltage at an acceptable level, even with a full-rated load (105V being on the low side).
i would think the starting watts on the grinder may be higher than the generators 1500 limit. and untill the grinder gets up to full speed its going to use more watts.
have you tried using other things on it? such as many lights, tv, fridge and see what it does.
most grinders have a startup watt of around 2000 and a running watt of 800 - 1200
This grinder has a running wattage of about 900 to 1000 watts, but like you say the startup wattage might be higher. But even so, shouldn't the voltage come back up after the initial drop when the grinder starts?
I had the grinder plugged int directly, and the light is built in to the end of a 15' cord. I'll have to fool around with it this weekend and try different tools.
i know wat the problem is, when you increase the lode on the genorater the engen needs to put more gas into the engine to ceep the (R.P.M)'s up. but because the thing is so old you might have 3 problems.,,,#1 your carberator needs to be clened out ,,,#2 your cilinder has been damiged,,,#3 you need to tweek the govener. for more info contact me at my chanol,,,Zmandt1993

Slow recovery after grinder removed means AVR, capacitor problem or loose/corroded wire from cap or AVR to field.

speed needs to increase with load, governor isn't working right.

It looks like a governor issue. The voltage is determined by the rpm so if the rpm drops due to load so will the voltage.

I think it's normal. My own generator puts at idle 219V out (49Hz) and with a 500W load somthing arround 205-209V and 45Hz. It's a 1200W generator.
I live in germany so we use 220-230 Volts and 50Hz.

Anything with a few hundred watt rating. I use a hand drill set to constant speed.

the engine should speed up when you turn on something on the throttle might be stuck or something like that
jay15kz 3 years ago
Yeah, that's what I thought it was supossed to do. I checked the throttle, you can move it by hand.
LynolsOffice 3 years ago
well i can't remember what it is called but the thing that is supposed to move the throttle could be bust for some reason
oh i just remembered it's a AVR automatic voltage regulator hope this helps

the grinder might just pull 2 much current. its a rather small generator, you might need a bigger one to run shop tools.
