LED Circuit Tester For Vehicle End

Updated 10/03/2022 | Published 10/01/2022

Question:

Is there a tool to test the female 7 pin connector on the 5th wheel? All the ones I see are female to test the truck/ male. Im chasing a short. Seems like every time I connect the truck to rv it blows a 15 amp radio fuse in the rv.
