Heh, after I learned that lead-free solder was used by Bosch in my
Volvo brick, mysterious electrical problems got a lot easier to
solve. All of the relays have been resoldered with leaded solder.
The next project is the instrument cluster. Something about the lead-
free stuff used not holding up well to years of vibration.
It also got cheaper to repair. Instead of buying a new headlight
relay for $200, resoldering the PCB in the old one works just as
well.
