Hmm I think you could be correct just strange that it works perfectly when the car is off.
thanks for the feedback though may give the regulator suggestion a try as well.
No not sure what i did with it will check in the car again but i do notice that the fridge switches off as soon as the System starts charging the battery and the Inverter seams noisy so I rather switch over to 12 volt connection to the fridge.
This is a very interesting discussion I have the Omega 800 Watt Inverter It's connected directly to my Deul battery system to run my Fridge rather than running it on 12v from the battery now wondering if this is safe to do as the deul battery is charging while the car is running. Any advice or...
