1996 EZGO DCS towed in run

muckinfonkey

I have a cart I'm working on 1996 DCS. I believe it was towed, they claim that "it just quit" then they towed it.....blah blah....I hear all the good excuses. I believe the cart was towed, it smoked the motor and controller (Alltrax DCX 300)
I have replaced the motor with a D&D motor and another Alltrax DCX 300, I also put in a new solenoid. I put her back together and I get no light or anything on the controller, no solenoid activity. I tried the new controller in another cart and it lights up and all..... I'm wondering if there could have been something else that got smoked in the process. I did not change the resistor diode on the solenoid as it did not look like it was exploded or anything. Im not sure where to head at this point.....anyone?

crash test dummy

i would go through all the wires .. look for broken or burnt ones ... do continuity test on each wire

A DCX controller has to have B+ on pins 6, 9 & 10 for Green Led to come on.

With Run/Tow in Run, Key ON and F/R in either F or R, check for voltage on those three pins.
If any is missing, or really low, trace it back to the voltage source.

A DCX is Plug-n-Play in a DCS, so a DCS schematic can be used or download DOC 100-51-C from the Alltrax site.

To get controller to activate the solenoid, B+ is applied to pin-5 via the pedal switch.

I suspect the blown controller took out the Reed switch, or the fuse if the alternate voltage source recommended by Alltrax was used.

A 300 amp controller with a D&D motor seems kinda small dont it?

Check the solenoid activation circuit and then the ITS signal once the controller lights up.

Thanks guys that gives me some direction.....the motor is stock equalivent
