I will try, but feel that it will be a short term fix like everything else I've tried. Is there any kind of long-lasting "contact enhancer" that could be used? I was thinking about anti-sieze paste. It has a lot of aluminum in it. I think you can get it with copper also. On Sat, Aug 20, 2022, at 14:06, Jim Cathey wrote: > Needle?

I pour it on the back and push it around with a stick. Don't let any drip through holes in the board, or drip around the outside. You don't want ANY of it on the components themselves. It could ruin them, and will certainly deface them so you can't tell what they are supposed to be.

Re: [MBZ] 79 300CD fun
Yep, if something's not working on my W123 or W116 it's either FUSES, vacuum, or mechanical. No computers. Closest thing would be the ACC, cruise control, and tachometer. None of which work on either of my cars.
