2016 EZ-GO rxv barley creeps then shuts off

[Robert4664]

So this is the second time this has happened.
I cleaned my battery post and after hooking backup the negative battery post the cart barley moves forward and backwards then shuts down.
i did start with (in tow switch and neg off first neg on last)

I still hear the clicks of the solenoid and brake when i power on and off with the key .
Also one of the four wires that are hooked to the last neg post arc real bad when i hook it back up. i cant tell for sure were that wire goes but it looks to me like the motor or electric brake.

I was getting ready to buy a new solenoid and replace it.

Last spark was charging up the DC converter, dont think so, try unplugging the DC converter & making that last connection. Hmm, no spark.

yes that worked for the spark thank you . this morning it started running again . it will power off if i hit a bump but take my foot off the pedal and it keeps going. you would think its a loose connection. went through everything i could find. wonder if the wires going into the motor could be loose. they are wraped so not sure if i should touch them. any thoughts ?
