Problems with Xantrex inverter...
I'm having 2 problems with my Xantrex 400watt inverter.
Here goes... I hope someone can help!
1) My inverter doesnt surviv Crank... Even if nothing is plugged in it, when I crank the vehicle, th inverter alarm sounds for 1-2 seconds while the car starts. If the computer is plugged in, it looses power and is forced a hard bootdown... I have read others here saying the xantrex survives crank for them?! WTF???
2) OK, I have my Xantrex inverter wired directly to the battery, and grounded to the body of the vehicle. I have my Xenarc plugged in the cigarette lighter. When the computer is turned on (powered by the inverter), there is some "interference" on the screen. Basically lines that scan from up to down on the screen, like when filming a computer crt monitor... I was told that the inverter could be causing interference on the 12v line of the Car, that was causing the itnerference on the screen. To test this out, I plugged the inverter with aligator clips, on ANOTHER car, so I had 2 separate 12v systems... There was NO INTERFERENCE. Then I powered the screen with the 110v PS it came with, fromt he inverter, together with the computer, again NO INTERFERENCE. Basically, I got to the conclusion that the inverter is causing noise on the system somehow... How can I filter it out? I dont want to have to use the xenarc 110v powersupply if the screen is 12v! (The above happens with the engine on OR off, it is not engine-induced noise, and henceforth is not to do with alternator or anything...)
Thanks for all help! Although I think at this point the crank part is getting me more upset! (Oh, I had my battery checked and they said the battery was fine... i should also say that I forgot the computer on, and the inverter drained the battery! It sounded an alarm but DID NOT cut the current! It is a Range Rover 4.6 V8 engine, with 100Amp battery.)
