does the unit have reverse polarity protection?

I not sure but we have never damaged a charger by accidently hooking it to the battery wrong. You would more likely risk explosion or damage to the battery or sensitive electronics in the vehicle you are jump starting.

Make sure the wiring polarity is correct... I had mine reversed by accident at first, and it didn't work (plus the power wire almost immediately heated up).

Yes, but be sure you have it wired with the correct polarity- see Joe K.'s response.

It uses deans connectors which determine the polarity. Search images of deans connectors.

Sorry, but I don't remember. Mine was used with a 12v DC converter for a light strip, so polarity is a definite concern

Yes. In a regular outlet it will indicate if the hot and neutral are reversed , if the hot and ground are reversed, if you have an open hot, if there is an open neutral, if there is an open ground and if the outlet wiring is correct.

It is not set up to reverse, however, it is a two wire 12v DC motor, and you could put a double pole double throw (DPDT) switch in the power feed to reverse the polarity, and thus the motor direction

There is no polarity on the switch. Connect the one to the POS+ from the battery and connect the other to the POS+ to the pump.

Not sure about that as mine is negative ground. That said, it should be ground polarity insensitive by reversing the connections.

Hi Joe - Sorry, but I don't know what the specs are on it, but is does have a reverse polarity switch on it. I connected it to my Kronos 88 and it performs very nicely. It's quite heavy compared to the brand X models, which helps it stay put while your performing.

Actually I hooked mine up backwards and nothing happened. On the back of the box it says it has reverse protection, short circuit, reverse night current, overload, and overcharge/discharge protection.

The switch is designed to reverse polarity for direct current....such as a twelve volt system....what are you working on?

I am guessing "NO" since I originally had the wiring polarity hooked up backwards and didn't have a reading.

Usually the center connector is Positive. Use your DMM to determine the polarity.

Yes it can. By reversing polarity you reverse the direction of the motor. A double pull double throw switch works fine at this function.

It's not reversed polarity. If the polarity is reversed the 63001 is completed non-responsive. I have the same unit. It is displaying -1, but otherwise appears to be functioning normally

You can plug it in either way, it is not polarity sensitive. You can not go wrong with this ths night light. We use them several places in our home. We found them once when we were staying at a strange/new/different location while traveling and really liked them and have bought 4 of them fof at home use, as well as, when traveling.
