Umm yes there must be continuity - otherwise there would be no current flow and no power. However it must have some resistance .. very low resistance .. lest see .. 100 amps @ 12 volts (typical max starter motor current) = 0.12 ohms ... so can you see 0.12 ohms on your measurement device?
If it worked before you mucked with it then you've done something wrong. Go back over what you have done.
