    Inverter Switch?

    Ok, I got my inverter in, but how do I tell which is positive and which is negative, if both wires are black. Circles below are the two wires. Got any ideas? Let me know if you need better pictures or other pictures.

    Thanks

    IF you're just talking about the two wires that run to the actual power switch on the inveter, there isn't a pos and ground. Th switch interupts the positive wire. So in a sense, both are the positive.

    Of course if you're talking about different wires, then I have no clue.

    Both are positive?

    If that's your power switch, it's most likely that the switch is making a contact (it could, alternatively, be breaking a contact, which I think is what Skipjacks was referring to.) In any case, one is positive, one is negative (or else there wont be a current to make/break), but it doesn't matter which is which because contact switches aren't polarity sensitive.

    As mushin said, the wires for the switch are just closing or completing the path for a low voltage circuit which is used to trigger the inverter to turn on. If you need to connect something specific to the positive side of the switch circuit then you will need a multimeter to determine which one is positive. Let us know what you are trying to accomplish and you may get a better answer.

    Hey good idea. I am trying to add an additional switch, located in my center console. The main idea is that I want to be able to take the inverter out, if the need ever arises, so I want to keep the current switch intack. Is there a way I could test to see what to do? I have a DPDT switch that I want to hook it up to and might have wired it wrong, since I did not have the inverter at the time.

    Anyways, that is what I am trying to do, got any more ideas?

    So, any more ideas? Should I just check the voltage of those wires?

    Simply connect your external switch directly across the switch in the inverter (parallel). Polarity does not matter in this case. Then when either switch is closed the inverter will power up. Use a connector in your wiring to be able to remove your inverter as needed.

    yea, that was my original option, but was not sure if it would work. I know that the relay would work.

    Ok, got the relay working just fine. Now I am having problems extending the LED's. I want to leave the factory leds, but just use some wire to extend them. Would I need to extend both + & - or could I just extend the + and ground the LED elsewhere? What would you call that, parallel or what?

    Would i need any resistors?

    Thanks
