Can a 12v dwell meter be used to check the 24v sytem if only a 12v source is used. I am not familiar enough with points and engine testers to go ahead and fry.. I mean try it. I have a Sears engine analyzer that tests 8 things, but of course its 12v. Is there a way to get around this. Brute4c has convinced me in other threads that dwell is the way to go but not sure if I have the equipment to do it right.
