I do not like temporary connections while doing board work .
If you can come up with a spare clip on / plugin , plug / socket .
Or solder wires onto the power connections .
The idea being being able to move the board as your working on it --- that your connections do not slip off / short .
Have you looked into " dim build tester " ?
A method of " non destructive testing " .
Part that is also using low voltage & current limiting to avoid damage - while doing board work / diagnostics .
Then also [ if you have them ] testing older gear , checking especially - electrolytic capacitors ?
Kinda like being a doctor " 1st do no harm "
