I have no idea what the exact ohms resistances should be... but if nothing is shorted or bleeding thru to ground where it shouldn't... then it's a cut in power at the beginning somewhere... or the rotor (the part bolted to the crankshaft) isn't distributing the field... start at the beginning... forget ohms for a second, think in "flow"... -Simple Doodled Diagram-

First, power comes from battery positive (after key ignition) and goes down the BLACK wire into the Regulator and then out the WHITE wire to the Magnet coil (small coil - excited field) portion of the charging system and then completed by the Green wire off that coil going to ground (or battery negative) {{that's it... end of the line for this part of the charge system - these wires have no 'direct' connection to any of the others}} - The WHITE and the GREEN wire here on this coil are the same wire, it's just wound around the coil core to make an electromagnet... dummy test by putting power on white, green to battery negative, see if it becomes magnetic...

The Regulator 'regulates' on the "IN" flow side for the variances in electrical system draw and motor rotation - a basic dummy test of the Regulator: Put power on the BLACK... you should have power out on the WHITE.... if not, then it's definitely not working...

Now, the YELLOW wires are the windings/phases on the other coil coming back... -- {{ The Basic Science: Feeding power down an insulated wire wrapped around a piece of iron or steel (ferrous metal) makes the iron or steel 'core' become magnetic (an electromagnet)... AND so the reverse is true, a magnetic field being spun around a ferrous core wrapped in wires produces electricity on those wires}} -- So, the magnet field generated from the 'excited' coil is being spun/transferred thru by the rotor and picked up by the other coil producing AC current on the YELLOWS... - So, AC current is now generated and flowing back on the YELLOWS (phases) into the Rectifier which then 'flops' it over to DC current and comes out the RED/RED WHITE wire back to battery Positive (+) - If just one of these yellow (AC phases) is not working, not producing AC current, then the DC output off the RED/RED WHITE wire will be weak or non-existent... also, if the Rectifier itself is no good, it can also make the output weak, or entirely fail to convert the AC to DC...
