As I’m thinking bout this test and the “You gotta disconnect stuff” , “NO! You don’t gotta disconnect stuff” discussion, it makes me wonder about the proper operation of the condenser as part of the ignition system. I got this book some years ago;
https://www.amazon.com/dp/B002I8H4WE...V170RD6O&psc=0
it has some interesting information in it and with regards to function of the points and condenser;
from page 131… in the split second that the gap resistance starts to create a voltage drop in the battery current, the potential (voltage) stored in the condenser will be greater than the battery voltage across the contacts. This being the case, the condenser instantly begins discharging back through the circuit, in opposition to the battery current. Thus, it effectually heads off and instantly stops the battery current, so that the contacts make a clean break, without any arcing of current across them…..(and on and on blah blah blah).….. we say that the condenser discharge constitutes an oscillatory current of rapidly diminishing value”
So,.. without typing out the entire half page of info about this all (my arm is still really hurting) I would think that if one was to engage in this “test” the second battery source and the function of the points/condenser should be isolated from the starter circuit? Yes? No? I thought that it was a bad idea to provide a secondary ground path...
Sorry, just trying to figure this out…
