First issue, not moving

Scott_nra

OK used my 93DS for the second time to retrieve a deer nothing even remotely hard on this one. Got it back, parked it for a few hours key off. And it when I got back on on it, I backed it up about 20' and when I switched it into forward it would not move. THought, batteries......? Checked and they needed about 1/4" of water. Watered, pushed it into the garage and put on charger. Tried after the charger shut down and nothing.

If you rock the cart back and forth it seems to engage and go but as soon as you stop it won't again.

Clues? I'm running on 3 year old batteries, lights work, back up alarm works, and when it does move it seems to go fine for a few seconds at least.

What Am I missing? Been running an 8" lift with 23's on the stock set up for a few weeks but have not really ran it very much. Probably only a few miles total.

To me this sounds like the brushes in the motor may be worn to the point they are not getting good contact.

I'm sure someone has had this problem and will respond with a better answer.

Put a DVM on the batteries and watch the voltage as you try to go

Let me add this, I have heard some high pitched buzzing from the motor area when climbing up a hill under a load since I got the bigger wheels a couple times. I figured that was something bitching at at me about it, but hoped it would last until I could afford the planned motor/Sol/SC/wires upgrade. I'm almost there.

Can't do the DVM check just yet. Want to be outside daylight with me assistant who is not here.

New info:

BTW it's an 03 not a 93!

Cart will move sometimes. You can hear the speed controller click on. Sometimes the Solenoid clicks and the wheels turn. Then sometimes it does not click at all and they don't but if you spin them a bit with your hand while the pedal is pushed they try to engage but it does not fully and there is no click on the solenoid. Battery pack over 50V, cleaned terminals on motor and SC. Starting the think SV took a big crap on me.

When the mtor does engage there are not weird noises from it like I would expect from a motor going bad.

Thoughts?

Update. Once in a while I was able to get the solenoid to click and the motor would engage for a moment. If you hold down the pedla with the cart jacked up and spin a wheel it will "bump" a bit but you can tell the solenoid is not engaging. I guess that was the high pitched squeal I was hearing when climbing a hill under a load.

So that forces me into part of phase two before I had all my $ together. Scotty b has me a Alltrax 500AMP sc and 400amp HD solenoid on the way. Should be back in bizniz in no time. Still plan bit wires and horsey motor as son as I can but I need my deer dragger back in action!

If that is an IQ DS (per your signature), it sounds like the field driver is bad on the controller.

The motor cannot develop any torque, but if you turn it by hand, it will continue to move. Of course the controller will shut down when it does not sense any field current flowing.

Check the F1 and F2 wires to the motor and continuity in the field coil of the motor to make sure the issue is not the motor.

But would I not hear the solenoid click? The tires do not continue to move either. But when it does "Click" the motor runs as normal until you let go of the pedal again. Either way, I have a new controller and sol on the way.

Brushes in the motor are bad as somebody already mentioned. Have it rebuilt.
