HGP,
It is typical of inexpensive digital multimeters not to give accurate readings below 1.0 Ohm ... so the reading on your primary may not be an indication of a problem. The shorting of an ignition coil is usually on the secondary winding, which is why readings lower than 650 Ohms is usually a sign of a bad coil.
I'm not sure I understand your comments about Voltage during the starting sequence! Are you saying that if you monitor system Voltage ... it starts with no load at something approaching 12 - 12.8 Volts, and before you even engage the starter ... something is loading the battery down??? If you use a remote starter switch to crank the starter, what does cranking load the battery down to? CDI systems don't perform properly below 10.0 Volts, and normal starting with a good battery should never drop that low!
That seems more like a short in the electrical portion of the ignition switch than an ignition system problem ... certainly nothing going wrong with the coil could possibly produce any loading down of the battery!
It really sounds like that at this point you are having issues with supply Voltage to the ignition syatem, and not actual CDI unit or coil problems!
