Did you mean transistor, rather than resistor? I don't recall a resistor in that 
circuit, but there's a transistor that gets broken leg syndrome, the common 
failure in that area.

In some era, around '71, Bosch used a cardboard spacer under that 
transistor, which tended to hold moisture, especially in damp climates. The 
moisture caused the leads to rust thru. Yes, the transistor leads were plated 
iron, which is more common than you might think.  

I use a plastic spacer when I replace that transistor.
