   Classy "creeper", I usually settle for corrugated card board😆️   
      
   I've been know to repair modules like that too. A lot of times it's   
   just something loose, especially with that ones age. I'm sure your   
   roads are nice and smooth too (cough, cough)😉️

   Cardboard is easier to slide on, I flatten and save large boxes for that   
   reason. Off pavement the hard solid plastic bonded to the bottom of the foam   
   doesn't soak through and pads small stones better.   
      
   The repair appears to have been quick and easy, a relay coil pin had visibly   
   broken loose from the solder on the single-sided board. The failure was   
   intermittent so time will tell. It measured connected, perhaps due to   
   handling or being in the cool basement. The component lead forming   
   intentionally allowed for thermal expansion and contraction, the small   
   diodes had half loops in one end, but the relay was tight on the board.   
      
   Very often I found that solder opens were the failure cause on boards. I   
   tested the soldering on fine pitch high pin count quad flat packs by sliding   
   an open safety pin from my key chain down the row. An unsoldered pin pinged   
   at a lower pitch.   
      
   In the 80's solder shorts on the inner planes of multilayer boards were a   
   problem, the board fab houses were painfully adapting from less dense   
   commercial to the nearly mil-spec requirements of computers. Often shorts   
   could be opened on a bare board by connecting a large cap charged to ~20V to   
   +5 and Gnd. If it wasn't under outer layer copper the fault would flash as   
   it cleared. This was a diagnostic, those boards wouldn't be completed. By   
   the 90's the quality had considerably improved such that visual inspection   
   found nothing.   
      
   Actually Maine and NH roads are quite well maintained outside of cities.   
   Pavement cracks are carefully sealed to keep water from freezing and   
   expanding underneath. The less densely populated areas of Mass aren't far   
   behind us. I've ridden on much worse in NY.
