I have a Cobra 1500W power inverter. The alarm is going off when the inverter is shut off. I drive a truck and have unplugged all appliances from the inverter and the alarm is still going off. What
This just happened. I shut my truck off and turned off the inverter during my home time so I don't kill the truck battery. Suddenly when the inverter was shut off and the three small appliances were unplugged from the inverter, the alarm still went off. When I power up the inverter, with the appliances plugged in, the alarm stops.

Re: I have a Cobra 1500W power inverter. The alarm is...
I can only give some general thoughts on this, I have patched up a few inverters.
Their core parts rely on a component called capacitors these over time degrade with heat which reduces their manufactured value this will mean they fail to fully do their job. The usual result is not providing a smooth supply rail allowing voltage spikes which trip over and under voltage sensing firing off the alarm, more so when not loaded with appliances as spikes can become large.
Your appliances would be snubbing out these through their loading but this can be trouble because they are absorbing this extra energy which may damage them eventually.
This situation will possibly get worse with the inverter failing, it will need a service engineer to work on it or to purchase a new one if there is no local regional repair place.
Look up faulty capacitors in power supplies on the web for an insight.

Restart your phone by holding down your Home Button and your Lock Button at the same time for about 10 seconds or until you see the apple logo. This will restart your phone and should resolve your problem!
When it doesn't start does it not turn over or does it not fire? When you are driving does it sputter and quit or just suddenly stop running? Does it make a difference what speed you are going? Does it happen after a certain period of time? Does it quit when going over bumps? When it quits will it start right away, or wait a little bit or get it towed home because you don't know when it's going to start again? Do you still have a carburator or throttle body? These questions would help to narrow down what could be causing your problem.
Hi Tammy, this can only be done if the load is not critical.... If load is critical then shut it down first.
On bypass you will be getting one beep every min or so Try pressing the inverter on button, there should be a single beep, and then if all is well the inverter will come back on line. All leds will then be green.
Suggest once working that it be checked to see if it will still support load during outage.
If this does not work then please post again.
In the manual there is pages of fault diagnostics which may assist, if you don't have the manual it can be downloaded from the Emerson website.
The DSW ProSub is a nice amplified sub. The reason it is shutting down is the amp is being worked to hard and it's going into thermal mode and after you turn down the volume and it cools down it's coming back on. To much of this and you will have a nice sub and no amp to run it.
One thing to do is keep the sub/amp in a well ventilated are and put a fan on it if you can to help move the heat away from the unit.
The amp is rated at 250 watts so if you push it to hard it's gonna keep shutting down. So turn it down a little so it runs longer and smoother or add another sub to the set up if you need it louder (like we all like). One sub can only do so much.
Also make sure if the receiver your using has a base setting or an EQ that you keep them levels set a little lower. Most receivers and home theaters already have an amp in them and you don't want to run to much of that into another amp. It's over kill. Find that happy medium.
If you have any questions or comments please feel free to ask.
Some bikes have a kill switch that shuts off the power to stop the engine should it tip over or be in a crash. It would need to be reset if this were the problem and if so it sounds like the switch is too sensitive or faulty. Resetting an ECM usually involves disconnecting the battery for a few minutes then reconnect and start the motor and just let it idle. Don't rev it. They usually reset in a minute or so during idle. If you drive it right away it could take 15 minutes to reset.
Looking at this, how many amps does the pump normally draw? Take this and multiply by 3 for start up current draw. Now, multiply that by 120 (volts) and this will give you the watts. Start up current is what will knock your inverter down. It won't kill the inverter but it will overload it on startup and turn off the unit. Since I do not know the size of your pump, this is my caution. You could always try it, the most that should happen is that the inverter will shut down.
