no. the cracked joints tend to oxidize inside the crack face.
remelting without removing this layer just leaves it in place and
compromises both mechanical strength and conductivity. you need to
de-solder to do this job properly.

the "simple" solution is replacing the relay - it's /guaranteed/ to
work. but that's still more expensive than buying the soldering iron,
solder and de-soldering wick.

In an earlier thread (1994 Honda Civic won't start) people recommended that I check the main relay to rule out a failed solder connection (for example http://www.tegger.com/hondafaq/mainrelay.html). Would it suffice to simply touch up the existing connections with the tip of a soldering iron? Looking for an easier workaround than re/desoldering just to rule out this simple part... Thanks.
