According to the Schumacher 750W power inverter manual it can take two 40 or 50 amp spade type fuses which can be found on ebay with the link below.

SOURCE: power inverter

There are 8 40A fuses inside this unit. In the following pics you will see a bank of 4 and another bank with 3 of the 4 removed. I'm currently working on mine as it will cost me more to ship and have Cobra repair than I paid for the unit ($133 to repair). Good luck with your problem

SOURCE: Power hook up

This type of inverter has large alligator clips on it because the amperage that comes through a cigarette lighter is insufficient and can result in blown fuses and overheating of the socket. Hook this one up directly to the battery without splicing a longer wire to it.

SOURCE: 2000 watt inverter blows 60 amp fuse under load

I have a background in electronics so i hope i can help. Now after reading this i have the feeling this item does not put out 2000 watts cause if that were the case it should draw somewhere near 147amps. This is because to find out amps you need to take the 2000 watts and divide it by 13.6 volts (assuming what the vehicle runs at) that gives you amps. watts/volts=amps.

SOURCE: Fuse missing

I would start with a 1.5 AMP fuse (175 watts / 12 VDC = 1.6 amp)
Make sure the fuse is rated for at least 120 VAC. Hope this helps!..Gary

SOURCE: 2nd season with 400 watt vehicle 1024 inverter. The

Restating the question - 400 watt inverter is turned on and running with the vehicle turned off.
After starting vehicle the red light of the inverter is on with no power output from the inverter.
If you turn the inverter off then on inverter operates normally.

Solution - this is normal operation - my inverter does the same thing. When you start the vehicle
it draws a lot of current from the vehicle battery which causes a drop in battery voltage. Most inverters have a low voltage input safety and will fault the device.'

If the problem is turn on inverter then the red light starts flashing... I am thinking you
have the same problem as the one I replaced - it broke... I am sure some capicator
or other component in the circuit failed... My solution was to purchase a new one...

My Shumacher 750 air compressor want come on now. When I put the gauge on it only tells how much air is in it but will not cut on.


Make sure that the motor is receiving power. If there is a starting capacitor make sure it is good. If all else fails you could have a bad motor or a frozen pump, either of which will cause your dilemma.

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.

What's your problem?how many amps on a 1/2 horse sump pump


750 watts is pretty close to one HP. However, the pump will have a much higher current draw on start up which may be too high for the inverter. (The accurate number is 745.699872 Watts per Horsepower)

Discounting any losses, 750 watts from a 120 volt supply will draw 6.25 Amps. so 1/2 horsepower should draw 3.125 while running. Startup current may be much more. Check your pump for its current draw (should be printed on the pump) and check it against the inverter's limits. It may be that the inverter is too light for the pump.

I recently purchased a schumacher 410w inverter, while it came on right away and powered my electrical device the cooling fan never came on. Is the fan supposed to run all the time, once its connected.


I recently purchased a Schumaker 410/820 watt inverter. I immediately hooked it up to a brand new deep cell batery I had purchased just prior to receiving this inverter.
I plugged in several devices to make sure the inverter worked and to get some idea of what devices I can expect this unit to handle.
I noticed that the fan only ran when I plugged in a device that drew a certain amount of power from the unit. I also plugged in a CPAP unit to make sure the inverter would operate the unit properly, and noticed that the CPAP only drew 38 to 40 watts of power and the cooling fan on the converter never came on. When I plugged in an oscillating fan it drew around 128 watts from the converter and the cooling fan immediately came on when I turned the fan on. Based on that, I would assume that the cooling fan in the converter only runs when there is enough power being drawn through the inverter to cause the inverter to heat up enough to cause possible damage to or failure of the inverter. I haven't taken the time to find out the power draw at which the cooling fan will run. Hope this helps.

I have a 1000 Watt Inverter, along with a regular car battery when the electricity goes out; Question: Can I use the 1000 Watt inverter and connect a 100 amp, deep cycle battery? I use regular house...


Yes, just be sure connections are heavy enough wire, and obviously the inverter uses 12 vdc input. Hook jumper wires positive to positive, negative to negative, on all 12 volt batteries. Deep cycle batteries will work better than car batteries. Just remember, when re-charging them, that they last longer when charged slowly, so don't use a high amp setting on charger and to monitor them closely, and do it in a well ventilated area, away from any ignition sources.
