I'd love to replace all four of these dirty contact and impossible to service without un-soldering troublesome relays with solid state units if such exist that will plug and play in my existing board.

Next best would be solid state circuitry that hopefully could use my board and still fit in the "module box".

I should clarify that the solenoid side is completely isolated from the contact point side. 30, 87 and 87a are not connected to 85 and 86 at all.

It's been many years since I was deep into electronics and thought I'd see if anyone here knew of a simple and elegant solution.

Thanks in advance for any help.

 

I do hope this isn't deemed un-answerable for being an automotive modification.

It really is just a solid state relay question and I'd be grateful for the help.

 

This question is against the rules of the forum for sure..
I'd expect it to be locked soon..

Good luck.

 

That makes much more sense than offering a simple opinion or suggestion possible components that may be viable.

The engine should be excellent for a tree chipper if this circuit would work reliably.
