When checking connections. I typically remove the connection, if it is a spade terminal or a ring terminal, i clean with a soft brass brush or a maroon scotchbright pad, coat with DeOxit and reassemble. I find that (especially in my evap cooled warehouse) the connections tarnish to some degree which in my mind causes nuisance coding. If it is a hardwired connections such as the connections of overmast cables on the distribution board. Once a year I cut all the cables and restrip for fresh wire connection. Usually end up with plenty of cable since the overmast cables stretch.


Code 333 from the book

POT1 (traction command potentiometer) above electrical limit

traction disabled

steps:
connect service terminal and access traction analyzer, traction input, view throttle. Center position voltage 2.4v to 2.6v, full foward travel 4.62v, full reverse travel 0.4v,

if: voltage is above specified range
then adjust pot 1 and calibrate

if: pot 1 cannot be adjusted
then check wire connections tb101-19, -20, -21, CA204-1, -2, -3, CA208-1, -2, -3, and CA403-7, -8, -15

IF: wiring OK
then replace POT 1 and calibrate.


TB101 is on the lift platform
CA204 and 208 are on the distribution board
CA403 is on the traction module MRC1
