All warning lights lit up, tried to resolder the CWS Module, still comes on an off...
Tried the most, think i have to get a new/used module.
928.641.602.04 is the part number on my module (86 Euro Twin Dizzy)
Will any other CWS Modules work, and what other partnumber will work?

 

Are you sure you’re getting the alternator signal that turns off the initial bulb test before changing the unit?

 

Thank`s for the advise, Have not checked that,
Should i check directly on the alternator, the 14-pin connector or somewhere else?

 

It comes through pin 1 of the 14 pin connector, a blue wire and then goes to pin 12 of the CW unit. Worth grabbing a copy of the wiring diagram if you don’t have it to trace it through.

 

Finally got it fixed, no more funfare/disco warninglights
Ended up changing the CWS module, bought locally at just 47$
The new CWS module is from a S4, partsnumber 928.641.602.05, it has the same wiring as my 86 Twin Dizzy.
