The problem of DRY JOINTS in soldered connections, particularly on PCB's, is
well known in the electronics and electrical industries. This fault is responsible
for a lot of the "Car starts and runs fine, but randomly shuts down, and won't
start until it has sat for 10 minute... " problems.
This pic is lifted from a good article on a Honda site, but what is written applies
equally to pretty much any older car that uses electro-mechanical relays. No need
to read the whole thing as the first paragraph describes the problem in detail.
So before you go spending your hard earned cash on new relays, take a look
inside and see if it has a dry joint. If it has, any electronics repair shop should be
able to fix it for a couple of bucks.
