Taylor Dunn Trident T2 won't run?? Help with line contactor

[Tustinhighmotorsports]

Hi everyone,
I am part of a high school group that got a Taylor Dunn Trident T2 donated for our motor sports competition club. We took the thing apart and now we are trying to get it to run. We checked the wiring and all and everything seems to be fine and we fixed alot of faults we were getting on the sevcon gen4 controller using DVT , but on DVT it says "local line contactor not mapped". We believe that the contactor is not closing properly and getting enough juice to the motor. Does anybody know how to fix this, whether with hardware or with modifying settings on the dvt software, or if we need to replace the contactor? We left it sitting for about a year but we don't know if the contactor is broken . Thank you

An easy way to tell if your contactor is fried is to apply a voltage to the coil side to close it, then check resistance on the contactor side using a decent meter. If it's anything >= 5 ohms, it's likely nuked.

Also, be warned that the gen4 is really picky about contactor wiring. Make sure to follow the sevcon design guidelines exactly, or you'll be stuck in fault hell.
