I have a 400 watt sunforce wind generator that is not spinning a lot and the red light is blinking on it

Question edited for a lot more clarity. Model and KVA helps.
Question moved from Televisions to Generac Guardian category.

Information to troubleshoot in the link and video.

The batteries are connected directly to the starting circuit of the inverter. If u don’t want it consume any power from the battery I would recommend an isolater switch between the battery and inverter.

The engine turns over the generator. We often think of a generator as one thing, but actually it is made of two parts. A motor to to supply mechanical power and the generator (a devices with electrical coils and magnets) that if turned will create electrical energy.
Since the engine is turning over, either the engine shaft that spins the generator is broken or a connector coupling is broken, or more likely the the generator portion of your generator is broken inside. Internal wires could be burned up or contact brushes are worn out. It sounds like your generator side is defunct. For inexpensive home emergency generators, it is usually cheaper to buy another generator rather than try to repair the generator you have.

A water heater is approx 4.5 KW too much for that generator, you pretty much asnwered your own quastion it is overloaded. Not to mention a water heater is resistive, not inductive thefore it is harder and you won't get a full3.2KW out your generator

Did you check The fuse can be found in the 12V DC barrel connecter

Most epoxies will soften and crumble when heated. This is the easiest way of loosening epoxied threads etc.

I went to the Black & Decker site and downloaded the pdf manual of the electromate 400. It says you're supposed to charge it until you have one red light, one yellow light, and one green light. I expect that 2 red lights and a green light means it's not fully charged. The manual also said you can't overcharge using the 120 V. method. Good luck.

sounds like a voltage regulation problem with the generator

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...

Yikes. I bet the bearing is bad in the fan and/or the fan is rubbing up against something. It might be an fix.
