From the pics it looks like you get a slightly lower resistance value between tip and number 3. This could be the same colored wires which should give a very low resistance reading, definitely much lower than what you're getting as they're basically shorted at the probe.
If this is the case I can't really figure out what type of failure would give such a high resistance between two shorted wires...
Actually the reading variance is more my inability to hold the multimeter steady. After re-checking all are 100ohms except the tip to center and that is like 98 or 99ohms which as I understand it should be zero.
