12V electromagnet. Wired neg wire. to neg terminal on battery, tried all three poles on switch. Wired to center "common". Nothing works. Help?

If I understand what you are trying to do you need to connect the common contact of one of the relays to the battery's positive terminal then connect your electromagnet to the NO (normally open) contact of the relay. Then when you activate the relay with the remote, it should work.

A diagram is not really required since this not a sophisticated device. Connect a ground wire to one of the small posts, and +12V from a switched source to the other small post. The wires that connect to the small posts can be small in diameter since it doesn't take a lot of current to switch the solenoid. Connect the wires that will be carrying the high current to the large posts and you're done.

If I remember, you can use either the positive or negative terminal. I connected to the positive side. You will need to purchase an additional cable Autozone). I used a 9" positive cable. I connected the positive cable from the battery to one side of the switch and the additional cable from the other side of the switch to the positive connection point. Did not have to touch the negative. Hardest part was creating a hole in the battery case (RV trailer) to locate the switch. It only took a few minutes to install and has worked without problems for a year. Hope this helps.

Hook up negative wire to terminal. Than touch the resistor to terminal and hold the other side of the resistor to the battery positive wire till the cap. Reads your battery voltage .. around 12 volts.. when it reads battery voltage than hook up the positive wire to cap. Terminal

I had an issue with the switch mechanism. When hooked directly to the battery, life is good. But when their switch is put inline, it doesn't. I replaced the fuse to no avail. I think got out my ohm meter and checked the fuse and the switch. The switch turned out to be bad. I'm now left with either returning the whole thing or just rigging up a toggle switch that I can buy at Home Depot.

There is a button on the back make sure thays is press down and if you have a multi meter check the nc with the neg end of the multi meter and the positve on the 12v in see what u get

HiThe battery is in a compartment accessible from the bottom.Remove the panel.Undo the connections and slide it forward out of the compartment it is in.It's laying on it's side.Make sure you note which are the Positive and Negative poles and reconnect then the same way.http://i1238.photobucket.com/albums/ff491/nohjekim/Images%20for%20Tech%20Forums/BatteryChange_zps7c2c9260.jpgMike

Make sure the little white plug from light string to ac converter (white) arrows align. The male and female ends will plug in either way but little arrows must align

Sounds like a loose wire. I did have another brand of led side marker light that did that. After I tried everything I reversed polarity and it worked. Just a though if you haven't found the cause.

I had a similar problem. Bummer. To fix the problem I had, I inserted a metallic washer between two batteries,that would make contact with the center conductor on the battery, but not large enough to touch the outer conductor of the battery. Now, everything is held tight enough to make good contact. The washer used is a counter sink type, so it fits around the center conductor, and can't move around. It has to be the correct size, to fit the battery + pin. Something else might work better, but this works for me. A spring that fit tightly around the center pin of the battery would probably also work, but I didn't have one on hand. I had a similar problem. Bummer.

As mentioned by others, drive in a ground rod and hook it to the negative terminal. We used a length of 1/2" hard copper tubing as the ground rod and used a commercial ground clamp to hook the wire to. Our ground rod is only driven in to a depth of 12" in clay soil and works fine. We anchor the positive wire to raised vegetable beds with plastic insulators purchased at a feed store. We have watched groundhogs do backflips when the wire was touched. Caution: Any leaves touched by the wire will be fried and continued contact will tend to shorten battery life. Also, be sure the light blinks when the unit is turned on.

You have to then connect a jumper wire from the positive and negative 'round buttons' at the top to the rails on the grid you want to be negative and positive, usually the red and blue rails. Lemmie know if you still have trouble I'll upload a pic

Sounds like a wiring problem. The terminal strip has 3 screws. The middle one is "common" and hooks to one side of your 24V transformer. The one nearest the valve (e.g., bottom) is the one which goes to your "controller" along with a wire from the "common"; the other wire furthest from the valve (or base) goes to the thermostat. The other side of the thermostat then hooks to the remaining (other) terminal on the 24V transformer. Sounds like problem may be associated with thermostat connections. If you still have the box it came in, check the diagram. Sounds like a wiring mistake but probably not a serious problem. Sounds like a wiring problem. The terminal strip has 3 screws.

You have to loosen the nut on the battery terminal and strip the wire and secure it under the nut. I went and bought an open terminal instead of using bare wire.

Sounds that you make the wrong pole on battery. Please stop it. And what is your battery type? Is it Lead-acid battery?

no. But I would disconnect neg terminal to be safe. especially at high setting due to high overvoltage. I have used it OK on riding mowers and small tractors fully hooked up with no problems

Turn off ignition make sure there is no load or disconnect Neg- Terminal, then Just connect to the battery and press the test button. I did not like this tester and returned it. Midtronics is the best in category
