Brake System light revisited
I have the original distribution valve. Is there anybody here that can test/clean/refurbish it?
It can be disassembled and cleaned.
The only thing that would be an issue are the O rings inside.
They might be a special shape and composition
But as my dad always said...
"If it ain't broke, don't fix it!"
Clean the outside, clean the inside.
As for cleaner... Be carefully what you use. The cleaner can't damage the O rings
Put it in and see how it goes.
Yes you can test it.
You could test it by plugging the ports except one on each side.
Apply pressure to one side and check for continuity between the switch post and the body of the block.
Remove pressure and check again, there should be no continuity between the switch post and the body of the block
Apply pressure to the other side and it should have continuity between the switch post and the body of the block
Anything else and it is not functioning correctly
