Is this right? - DVM is set do DC Volts
- Black DVM lead connects to positive battery cable at the starter?
- Red DVM lead connects to positive battery cable at the battery?
- Crank car.
What should peak value read if the cable is good vs. bad?
Good means voltage drop of .5v?
Bad means no voltage drop? |
Tried to learn about voltage drop again.
I think I was accurate above.
The key for voltage drop is to test while current is flowing.
Otherwise, you can read 0v (12v at both ends of the cable, even if there is an issue)
