1999 DCS Controller Dead???
I have a 1999 EZGO DCS Limo converted to 48v 8-6v batteries and alltrax dcx400 controller. My wife was driving cart up a hill at normal speed when it just stopped. Now it wont move at all not even a small jerk. Batteries are full at 51.2v and each individual battery reads 6.4v all connections are tight.
The controller is always in a state of on even if key is off. When tow/run is flipped back to run controller flashes 4 times and then stays solid green even with the key off. Alltrax troubleshooting says to remove B+ and M- and connect dvm to see if it powers up when tow/run is switched or when key is turned. Mine powers up with tow/run switch. The troubleshooting says I need a new controller. I just want to make sure others on here feel the same before I drop money on a new one. Thanks. |

Key on, select forward, test leads on M- and B-. When the solenoid clicks you should have pack voltage(50v) this reading should decrease to 0 as the peddle is pushed down.

Re: 1999 DCS Controller Dead???
ok scotty Checked that and I get 28.3 volts not 50. With pedal depressed volts drop to 0. I also forgot to mention that when I turn the key and place it in forward or reverse the solenoid clicks on and never clicks off until direction put in neutral.

Can you put a battery cable jumper on the solenoid big terminals and try it?

Re: 1999 DCS Controller Dead???
I will have to get a battery cable. I do have 51v on battery side of solenoid at all times. The controller side has 50.8v at all times whether the solenoid has clicked or not.

Re: 1999 DCS Controller Dead???
You are reading the precharge resistor. Grab a cable and lets eliminate the solenoid from the equation. I have a customer with a PDS cart getting the same 50% reading at B- and M- ... I'm sort of confused by this if the solenoid is good.

I think your controller has failed.

Re: 1999 DCS Controller Dead???
OK so I got my new alltrax dcx 400 controller installed today and still have the same problem. Its always on even with key off I only have 28.8v across m- and b- and my cart won't move. My solenoid comes on when key is on and direction is forward or reverse but it never shuts off.
