Title: Tail light problem K75S 1990
Post by: kjel-man on July 22, 2012, 05:45:29 AM

Hello!
I have a strange problem with the taillight on my 1990 K75S (ABS). When I put the ignition switch to parking light, both the backlight and front bulb light up as it should. When I put the ignition switch in the start position, both bulbs turn off.
Does anyone have an idea what this error might be?
Kjell

Welcome Kjell!

If your cluster light shows when ignition on, the problem is in the ignition switch.
If the cluster light doesn`t show, the problem is in the light on/p/off switch.

Thank you Inge K! 
The ignition switch is brand new. The cluster light do not shows, so it must be the light on/p/off switch.

The problem could also be in the switch assy connector under the tank,
the grey/blue wire is the park/tail/cluster feed, measure at both sides of the connector.
