The controller positive voltage is common while the negative is controlled. How do I control a moter with common negative with battery?

Yes, I found this strange too. I used this in a car application. Had to hook up both positive and negative through the switch to make this work. I thought I could ground the motor, and control the positive. Oh well. Still got it to work.

It is a simple input/output arrangement. Power source is the input, supply to whatever device you want to vary the speed of is the output. This will only work in one direction, unless you swap the output polarity to run it in the opposite direction. Doesn't matter whether the + or - is the control path.

Thanks, i'll check for the switch on the back tonight. i'm sure the polarity is correct, red to lead (+) and black to ground (-) right?

The white and yellow hook on the small screws on the shunt. The black wire is negative battery or a ground. The red and green are both hooked to battery positive. When pushing the small switch on the front, the readout switches from amperage to voltage and vise versa.

leave them connected unless you feel there is a short, something drawing current, in the system. in older vehicles where there are no clocks or electronics you can remove the negative cable and put a 12 volt, pull fues test lamp with one lead on the negative battery post and the other on the cable , if it lights something is on, pull fuses until the light goes out

Yes, two six volt in series. Connect the + of one battery to the - of the other, and then connect the controller to the plus and minus ends as if it were one big battery.

Generally on the mower you have caps that cover the connection at the end of the cable that attaches to the battery. Pop the cap cover off the terminal and attach the red to the positive and the black to the negative terminals. Be sure not to get them mixed up.

I have a tri star 45 pwm charge controller. It is a negative ground and also has a ground terminal on the case. Works good.

Find the battery first. Could be under the seat ? or under the hood ? The wires hook to the battery and one place they hook usually has a + sign for the positive or "red" clamp the other a - sign for negative "black" ground connection. The main thing is to identify the + positive connection and make sure you hook the red clamp to it. One way to identify the - minus or ground connection is to trace the wire and see what it connects to away from the battery as it will connect to the frame of the mower and the + "hot" "red" "positive" lead or wire will go to the starter motor on the side of the engine. Hope this helps ?

not wired correctlymake sure to test the polarity and voltage of the post that you attached it toIf not the full voltage of 36 or 48 whatever your cart is it will give that orange/red indicatorIf no voltage meter available just start going to different battery post

It should read 12 turned off and 14 on. Any lower or higher something is wrong with your batt or alternator

the controller prevents reverse polarity. remove the diode it does not do anything

I think they all do that. I have a separate battery monitor Trimetric. You really need a shunt on the battery negative for an accurate SOC state of charge. The MT-5 provides info about the current going in and out of the charge controller

Doesn't matter how you wire them since the driver circuitry has an inverter bridge. They can run on 12V AC or DC. I believe the wires are black and red so following convention I wired black to negative and red to positive.

There is two stray wires for positive and negative. You can connect it to batteries. Connect it to a 12 volt source i.e. inside cab lights.

Connect the positive cable to one end of the battery bank and the negative cable to the other end of the battery bank if possible.It would help distribute the load evenly.

There should be a switch and the settings marked on the side of the battery enclosure. You have to look closely to see the settings.

Hi Shard, my initial assumption is that you do not have the connectors in the right place. The batteries are connected in series i.e. mine are 6volt batteries and I have 6 of them for a total of 36v. So the positive connectorhas to be on the 1st batteries positive terminal and the negative connector has to be on the negative terminal of the last battery. If you have it hooked up that way, one of the batteries might be bad. Bill
