Have been looking hard for a 133-919-431 relay with no luck so far. Bosch#0335412002 or Hella#5SA002851-00 Does anyone know of a source for this?TIA Dennis (IMG:style_emoticons/default/confused24.gif)

Your best bet is place a WTB classified - looks like you have that covered.

Someone will come up with one for you.

I’ve been playing with these trying to better understand how they work and how easy they might be to repair. They are very complex for what little they actually do. Basically 70s era discrete components used to make an analog logic via transistor switching.

I have posted info on the basics of how they work and how to bench test. (Link below) I apologize this thread isn’t complete yet - I’ve run into some challenges that have me somewhat sidelined at the moment. I’ve also run into a bit of a technical challenge that I haven’t been able to solve (yet) trying to revive a unit that was previously non-functional.

If I can be of any help - let me know and I’ll do what I can.
