Certainly, a zero ohm reading is an indication that pin 4 or the circuit
trace or relay K1 pins 3 or 6 are shorted to ground somewhere. It could
also be on relay K2 depending on the state of the relays or could be caused
by a shorted crystal, or excess solder that wiched up onto the crystal lead
and shorted it to the case.
Check the soldering, especially for excess solder. Just enough to fill the
plated thru hole is sufficient, and if there is much more than that, it can
create solder bridges and short one circuit to another.
Name and call please?
