You should run a dedicated cable back to the battery.

The main reason for doing so would be to ensure the cable capacity for the inverter. If you have the equivalent of 2ga cable at the battery post, and your inverter wants to use 100 amps (1200 watts), you have exceeded the capacity of that cable, which also serves the rest of the vehicle electric. In the same scenario, lets say that the frame of the vehicle has a total resistance of .1 ohms as seen by the inverter. Pass 100 amps through that resistance, and you now have a voltage drop of E=I*R = E=100*.1 = 10 volts. The inverter isn't going to tolerate that for long, and it may also cause havoc with other electronic devices as well. Your cable connections will have a lower bulk resistance, usually so low that it becomes difficult to measure accurately with a meter.

I have a eu3000 is honda generator i have replaceil and controdule and i still have no fire why


Check the ground wire that goes from the negative side of the battery to the engine block. I have seen them break at the connection on the block. You can test to see if it is broken by connecting a wire from the ground lug on the side of the generator and holding it to a bolt on the side of the engine and see if it will start. Also the low oil sensor will prevent the spark if you are low on oil.

How should I hook up a 2000 watt schumacher inverter to a 12volt battery


i normally mount it under my seat run one lead straight to the positive (red) lead of battery with a 30 amp fuse using an inline fuse holder fully sealed.than the ground (black) using a ring connector to the chassis or seat mounting stud.must run positive under carpet and through fire wall using a grommet or other possible wire channels.

No spark


The grounding wire that grounds the engine frame to the negative side of the battery may have broken off where it connects to the block. You have to take the red metal shell off to get to it. You can easily check this with a piece of wire ( I used one wire from a set of jumper cables). Clip one end to the grounding lug on the side of the generator, and the other to a bolt on the engine block. See if it starts. If it does, you need to fix the grounding connection. I used one of the braided ground straps that you can get at an auto parts store.
The engine/generator assembly sits in there on rubber motor mounts, so it needs to have a way for the ignition to be grounded.

No spark on EU3000is


There is a grounding wire that runs from the negative side of the battery to the engine block that has been known to break at the spade lug where it connects to the engine block. It is connected on the block on the side of the engine opposite the door, so you have to remove the whole red shell cover to get to it to fix it. Without having the engine grounded, you will not get a spark. You can easily test to see if that is broken by connecting a wire from the ground terminal (on the side opposite the door) to the engine block. I used one of my jumper cables and just clipped one end to the terminal and the other to one of the bolts that I could get to inside the door. I have seen this on a couple different ones. I went crazy the first time... went as far as replacing the oil sensor figuring that was grounding the ignition..and it was this stupid ground wire. Finally fixed it for good with one of those $5 braided ground straps that you get at Autozone and went from the frame to the side of the engine.

Hi. I keep blowing inverters. I had a 1200 watt Coleman that went out while running a fan. Just installed a Cobra 800w inverter in my Dodge Ram under the center console. I had it wired to an outlet on my...


Well without knowing exactly how you wired it, it is hard to say what happened. A little diagram would help. But, with nothing plugged into the inverter, the wires must have been shorted. What size wire are you using? If you have an 800W inverter, the amperage on the secondary, (120V) side is only about 6.5 amps. So if you ran 14 ga wire (smallest you should use on 120V ) that should be fine for the 120V circuit. Do not connect any of these wires to anything but your remote receptacle. Now for the primary. Notice how large the terminals are on the supply side, if you have an 800W load @ 12V that would be approx 66amps. Therefore you should have #4 or #6 copper wire going from the battery to the inverter. This wire must be fused, and I'd fuse it with a 60A fuse. You can buy nice fuse holders like they use on amplifiers that connect right to your battery. Now on the 1200W unit, you can imagine the difference. The secondary would be 10amps and the primary would be a whopping 100A. Even if you have a large alternator, I'm sure it is not rated at 100 amps continuously.

Make sure the ground from inverter to frame is intact. Make sure the positive and negative connections are clean and tight. If this all checks out, disconnect power to the unit for 1 hour and let is reset. If it still shows a fault then you really need to send it back to the manufacture for repair.

I bought two Victor 750 watt inverters ,and was led too belive i could stack them and get 230 volts. This did not work ! why.


In order to get 230 volts out of any 115 volt inverters you would need to be able to hook the outputs up in series with each other. If your inverters have outlets there is no way to do this other than completely dismantling both units and then I wouldn't advise it. As a licensed electrcian and electronics tech I've sometime done things like that but only as experiments or in emergencies.
If your units came with a power(+) and ground(-) you could then hook them up in series by fastening the (+) from one unit to the (-) of the other, then tape them to insulate them. You should then show 230 volts from the two leads still available. On the battery side you will still hook both postives(+) to the positive(+) and both ground(-) to the negative(-).
Notes:
* Depending on the internal wiring of your units the above description may not work and could damage or even ruin your inverters.
* Although you may get 230 volts this way you will not have more power(watts,Amps) than listed for one unit and you may even have less.
* You need to also beware this could VOID any warantees and shorten the life of these units.

Sounds like your a truck driver. Anyways you would hook up the ground to the negative and the hot to the positive side. The 4 batteries are in a series so just pick a negative and positive. I hope this has helped, please give a rating on the answer. Good Luck and have a great weekend.

Fan does not work.


Two things...one the fan only workk when the unit get hot or you created short the inversters are very sinsative and if you make mistake you are dead...see try it for ferw min and see...but first try to reset the unit and that by disconnecting the negative and positive from the back and turn the unit on to get all charges in the unit out then reconnect the cables do not forget to ground the unit to avoid sparks.

I have no instalation instructions for my 2500 rppipower inverter


You should use 2 red and 2 black cables, Install the inverter as close to the batteries as possible and use minimum #4ga cables #2 are better. Keep the cables as short as possible. You will need also connectors, like the ones on the truck's battery cables, attach these to both ends of each cable and crimp VERY well, connect all 4 cables to the inverter first, then the red cables at the positive battery terminals (if 4 batteries use one on each end) then the black cables to the negative posts the same way.
