Idle speed control
 

The unit in question is out of a 1990 420sel, At the point of the second deck (printed board) the entire solder conection is brown,the entire row of pins at both sides of the upper deck,where conected to the main board all of the solder joints are brown,can this be from to mutch heat? just-n-time :confused:new photo to view.

brown?


like a solder flux brown?

Brown
 

Yes now that you say it that is just what it looks like,But why only in those two area's?:silly:

is a a re-done unit?


or


does that area have any electrolytic caps around it?

Rebuilt-No
 

I don't know what electrolytic cap's are! But if it helps the unit has two levels to it, and it is at the point of soldering them together that the brown
streak appears. j-n-t:silly:

I wouldnt worry about it to much, unless you have idle problems.

Well yes I do but not till it warms up.j-n-t:silly:
