Question about Electrical Supplies

1 Answer

I have a honda ex1000 generator. The owners manual gives specs of 120vac at 3600rpm. Also 12 volt dc to charge a battery. It starts and runs great but measures 240 vac at both receptacles. There is no regulator on the unit. Is this wired for use in Europe or Australia?

    I appreciate the wiring diagram. I got the owners manual from the owner of the unit and it has the same information you provided. I cannot determine which, if any, components might be the cause of the boost in output. The dc volts at the terminals on the unit read 30 volts in addition to 240vac at the receptacles. Could a defective rectifier allow these readings? I have not found any burnt wiring or harness connectors. I am not inclined to tear into the generator part as I really don't know how to properly test the system components.

If it is in fact made for the country's you stated then that's common do to they don't use 110 but unlikely do to there sales are international in reading the manual the rating is
120volt 60 Hz rated 900va max 1000va
the 12volt section 12volts 8.3 amp current
i am attaching 3 pix's of the wiring diag so you can trace the wires hope this helpsI have a honda ex1000 - b34e74f.jpgb589d04.jpg1eb189d.jpg

    at the lower part of the wiring diag you see the stator housing ther is a set of Diodes these need to be checkedthey will need to be removed and tested to test use a ohm meter and set to the Diode setting or the 200 to 2000 ohm's settings the diode will have a stripe this is the cathode side to test place one lead on each end it won't matter you should read any reading when you reverse the leads you should not get a reading if you get a reading bolth ways replace them same if you dont get any readings as to the rectifier yes this will cause i issue as to testing you need to have the specks for the diode it is nothing more that 4 Diodes in a package but you need to know witch points are the annode and cathode it is better just to replace ther only around $5.00 and under i hope this helps. please repost your findings

Generac XP8000E how do you replace the battery charger fuse 1.5 all I can find out is you have to remove the control panel. No manual and can't find any info


1st check the voltage going into the Battery Charging Rectifier from the alternator. You should get between 12 Volts DC to 16 Volt DC with the engine running.

If you get these results next check the battery. You should get max 13v dc going to the battery. If your battery is not charging on this unit or gets under 12x dc, you need to replace the battery charging rectifier.

If you need other parts you can find them on this page.

Hope this is of assistance to you!

I have a 6000 watt allpower generator that the 12 volt breaker poped out reset it still no power replaced the avr ran for about 5 seconds then poped the 12 volt breaker again what could it be


The 12v system does not go through the AVR. It most likely is the Battery Charging Rectifier has failed. This controls the voltage from the 12v feed from the alternator and charges the battery.

1) Follow the wiring from the 12v socket/connectors until you come to a Block rectifier. It will be held on by a bolt in the center and have 4 wires connected to it. If you look at the pins you will see one is seated at a different angle to the others. Test the feed to this pin, you should get a result of between 12 Volts DC to 16 Volt DC.
If you are not getting these results then the Block rectifier has blown and will need replacing.

2) If all is testing fine above, then you will need to test the Battery Charging Rectifier as you have an Electric Start and Battery on your unit. This is a metal block located on the back of the engine, next to the starter motor and it has fins running across it. ( to see an example of this part look up your generator on this page Again this should be giving you between 12 Volts DC to 16 Volt DC.

3) Next,check the voltage going into the Battery Charging Rectifier from the alternator. You should get between 12 Volts DC to 16 Volt DC.

For replacement parts please see our web page. You will need the full model number to do this.:

the generator is not big enough to run what you want
it needs to be 3500w minimum or 4.5w to be safe
although it is stated at 2500 watts , in fact that is the peak load on electric motor start up and its continuous rating will be around 1.8 watts
all of this is clearly stated on the specs plate on the generator

Bike won't rev out

Could be electrical.Bikes that have generator systems need battery induced.Unlike an alternator system,like a car you can jump start and the alternator will run with good spark to fire fuel.Generator type need battery induced,so battery must have correct amperage.Can test battery with a volt or/amp test.See what you have with bike not running,then running need about 20% more volts then the 6 or 12 volt battery states (about 14 volts running on a 12 volt battery.Know your battery life span & know that a new battery that year.Plus generator must keep battery charged.I like to have a good spare and also go for a glass mat battery especially if bike is ridden season related. Good Luck!

Get a cheap digital voltmeter put it on the DC volts range. Place the red lead on the positive terminal of the battery and the black common lead on the negative terminal. Jump start the car again to get it running. If the battery reads in the range of 13.6 Volts DC volts then the alternator is supplying enough power to charge your battery. The alternator must generate more than 12 volts Direct Current to charge a battery. Also check the belt is not slipping on the alternator pulley.

I'm dumb. Can I hook an inverater to my generator and produce more enegry than my generator produces???

Please understand that the generator produces power from fuel with an engine wheras the invertor is one which genrerates power from a stored battery using the principle of frequency switching a DC source to induct and produce AC.
Now you can have an uninterupted power supply setting with the invertor backed up by the generator so that when the battery voltage goes down you can start and charge the invertor and also supply the extra energy .
the ratings of both must also be considered.

Where is the generator

left side,there are three wires going into casing.they go to the stator. FUSES and volt regulator can appear to be bad alternator too.charge battery first,then unplug the three wire connector ,start bike , with voltmeter in volts ac check for output on these wires(do not check against ground but from one to the other until all 3 combinations have been noted) if none can be found its bad,or if all 3 combos do not have 50 volts AC or so with engine rpms around 2000 .next is volt reg. its output is in DC volts and should be 12 to 15 volts dc.

My generator eu3000 will see its third winter in Western Washington and it does not start with the key. My wife needs the generator to run an oxygen machine, so the key start is critical. When I try the...

The EU3000 is a gel-pack (spill-proof) battery. Using a 10mm wrench or socket, remove the four (4) screws that hold the end cover on the machine.
Use a voltage meter and test the battery at rest (no load, not running). You should see 12 or higher volts DC. Record the voltage and then start the unit manually. Turn the ECO throttle "OFF" so the unit revs up to full RPM. You should see 14 or higher volts DC to verify that the charging system is OK.
The conclusion:
If the 12V test shows less than 10VDC, replace battery.
If the 14V test shows less than 12VDC, have a HONDA AUTHORIZED shop diagnose it for you.

Hope this helps.

Runs great but will not produce electricity

To flash the excitor circuit on a coleman ( the generator is built by generac) you need a 12 volt battery. You quickly apply 12 volts via your 120vac recepticals. NO MORE THAN ONE OR TWO SECONDS! Then check you ac voltage. Most of the time the brushes are burnt up when voltage is low. Check the brushes first. You can access them by taking the end cap off of the generator via two to four screws. The brush holder is easy to spot, two wires leading to the front of the amature. Hope this solves your problem.
