This question was answered on another forum so quoting autonerdz

What I understand you to say is you want to do a voltage drop test on the starter positive side.

If this is correct, then keep scope grounded to bat neg and deploy two channels, one on each end of the circuit. Then you can do a math channel like A-B to display the voltage drop.

Avoid ever placing a channel ground on a voltage supply.
