OT: Question about auto electrical test device

[mcgarrett]

Rotorwrench,
I appreciate your helpful explanation. As previously stated, I'm electrically challenged to some degree although I do have a pretty good grasp of the basics. For my 6 volt, positive ground cars I would like to use this tester to check things such as coils, condensers, RPM, dwell, voltage, amperes, point resistance, etc. It has settings and instructions for testing all these functions and more. I just want to be sure I connect things correctly without creating a big fireball and smoking the unit.
