Hey Scooterman, we have our motors built to our specifications, we do not manufacture them in house. We designed the performance levels of our packages to work specifically for the Precedent.

Thanks for the question!

Lakebit, the new software to accommodate the 7144 motor is working well. It no longer has those neck snapping starts. It takes the hills well and I don't feel like I am a traffic hazard. It still slows down a bit on hills but not like before.

At first I was ready to give up on the Alltrax but since I got everything upgraded I am a happy driver. The new DPI charger made a big difference also by always having a full charge especially in this cold weather.

I'm still tweaking the settings so it isn't a finished project yet. BTW with the correct patch installed for the 7144 motor the field map number is 44.

Thanks for the update jj

I'm still using my stock motor but have decided the 7144 will be the motor I choose if I decide to upgrade

Good to know the field map change works well

Took cart on vacation ran for a day but felt like rear end moving at slow speed smooth at high speed. Quite yesterday after short trip.
Read MCOR with meter jumped blue and green wires on micro, no luck.
Let sit for a while cart starts and makes clunking sound then stops.
Jacked up this AM blocked pedal runs for short while stops and controller red LED blinks six times.
I don't have paper work for controller with me and need to find a way to load for return home. Is there any chance of repair with limited parts?

6 red blinks = low voltage

Make sure batteries are charging.

Make sure all cables are making good connections.

As Sergio said, make sure your batteries are charging. Be sure when you plug the cart in you wait around for the charger to kick on.

We have a couple carts with the alltrax controllers in them (we are just in the middle of switching the alltrax controllers out) When you plug the charger in they don't charge, so what you have to do is unplug the charger, cycle the tow run switch and then put the cart in forward and get it to move. Then plug the charger in and it will come on and charge away as normal.

Battery indicator showing full charge, checked with meter read 50.8 v plugged in charger needle at 15 a for couple min dropped out charger for few sec started charging again. Charge indicator dropped to 5 a with in 5 min clicked off and back on. Battery pack at 60.1 v with charger at 5 a.
Will check all connections again after charge complete. No loose connection found this AM.

If the cables are good, inspect the solenoid pre-charge resistor for signs of overheating.

The low voltage error code is detected at the controller B+, so if the solenoid contacts are not closing, the voltage would be low because the current is running thru the pre-charge resistor.

Resistor looks ok, read 430 ohms across solenoid. Voltage from battery neg at pack to green wire on motor drops from 51 v to 47 v as pedal depressed controller faults.
I do not here solenoid click only micro switch.
Is there anything I can check on control circuit before I jump across solenoid?

Do you think it might be something dumb like the under voltage adj set to high and shutting you down. If you got your laptop set it to about 20 volts. Also you could temporally decrease your max output current to 80% and see if that gets you going.
