The TCD-W has the wiring to chassis and handlebar multi-switch pass through a connector on rear top of the TCD's plastic case.
The connector is held in place with the four small philips' screws visible. The internal side has Eight (8) contact pads on a circuit board secured with Two (2) tiny P' screws. The contacts are arranged with Four (4) on each side of the board. There is a two banded sealing surface on the external circumference.
The TCD internally has two rows of spring loaded floating contacts to mate with the wiring connector's Eight (8) pads upon insertion.
... when the Como fell over, the external wiring at top rear of the TCD hit the car door and distorted the screw in connector enough to bend down the internal spring loaded contact pins on one side. When battery power button was pressed, the light winked and battery indicated charged but absolutely no motor. Even tried holding
+ button on multi-switch for 'WALK" mode but NG.
.. with some background in electronic controls, dental tools, and a 10X view scope I carefully
"FORMED" ( bent !) the TCD's four bent pins somewhat back to their intended positioning. Put all back together and tried turning on but still didn't work.
... convinced the connector was the issue, revisited connector and removed circuit board two tiny screws and added spacer under pad board to move it toward TCD's pins. (3 layers duct tape added @ 1'32")
... . put all back together -fired up batty switch and sure enough TCD-
W Display and Controls and bike
works as it should!.
... been talking about it with the LBS who is being very helpful relating what seems to be the bikes'
Achilles Heel.
bike hit the door of the '63 left a skidmark.
