SOURCE: add electric start to dg7000 generator by Dewalt

This is really not an option. The engine would need a starter motor and battery and starting key switch. You will probably have to replace the unit with an electric start option.

Does your motor run at the same RPMs that it did before? It sounds like your motor is running to slow to produce the 120V ac.

But it could also be that you have one or more diodes blown.

Since the generator is selling for $1,100.00 on several sites, make sure that you don't spend more for repair parts/labor than what you can replace it for.

Anything can be repaired, but some aren't economically repairable. So if you have to pay someone to work on your generator, it might be better to replace han repair.

Why do i only have 94 volt output on dewalt generator 2900 watt


It should change with the load, the more load you put on the line the magnetic field increases with the amperage and the gen will produce more output until its rating is reached. This happens especially if it has been sitting a long time.

Output voltage adjustment


Output voltage is based on 3600 rpm @ 60Hz. Sounds like your generator is over speeding slightly. Put a Frequency meter on the output of the generator and tune it to 61.5 Hz, that will get your generator in the 3600 RPM range.

I want to change 120v charger to run on 240v.What components have to be changed?


Can't be done.
Even if there was a safe way to put power to the neutral wire, the fact is you would still be running more than twice the power through it, and it would blow up. It would get much hotter.
Nor would the charger put out 7.2 to 18 volts any more.
It would put out over twice that.
The only way it could be done is if the unit was intended to also be run on 240 volts, and had a European selection setting switch.

Can you put a aussie 240 volt plug on an US battery charger


Look at the specs on the label, if it says that the charger is capable of taking a 240v input then you can change the plug and use it at 240v with no problem. If it says 120v then you won't be able to, you'll want to use a transformer or some other 240 to 120v supply.

My generator is not putting out the proper voltage? it's only putting out approx 75 volts on the 120 volt circit. i adjust the idle to full out and i get approx 112v.


Most low voltage conditions on generators are simply due to a low engine rpm. Most modern generators are 2- pole windings. So your engine rpm should theoretically run @ 3600 rpm. which will produce 120/240 volts @ 60 HZ. In actuality You want to set your rpm's @ Approx. 3720rpm no load. About 62.5 Hz. Without getting to technical this will give you your desired 120/240 volts loaded. Hope this helps.

Homelite portable generator, LRIE4400...no out put fr unit..has been discontinued fr a few yrs..no parts available..known fr circuit board failure..my dad's , maby 50hr on unit..how can I bypass..or obtain...


If the engine is running but no output from the plugs....the VERY common problem is loss of magnetism in the generator after storage.
With the generator off.........
Look at the side of the generator part.....do you see a small + and - on any terminals?
You may have to take a cover off.
Take a 9 volt battery and momentarily put current from this small battery through these terminals.
Now.....start her up and check for power at the plugs.
This fixes 75% of "no output" after being "stored" generators.

Dewalt charger


Ok, for easy way, you can just put a 1~2A diode in series of the input 240v power wire, so the after voltage would be around 120v, but for precaution it is better that you put two diode in series, it will give you same result. In addition, I have already tested it on a similar charger, it works fine.
p.s: I do have a similar one that is also 110v, I compared it with other 240v one. They worked same.
