I agree, check the points. They often have a non-conductive film on the contacts that needs to be cleaned off. Use your fluke to measure the resistance across them. Should be zero Ohms when closed. Not an Ohm or so, but zero. When open, you will see around an Ohm, the resistance of the coil primary winding. Secondary windings at around 6-7 Ohms is fine.
