My ring says B.S.M.E. So much for one upped.
I did misunderstand what MK was talking about and that version of voltage drop will test the circuit continuity.
My experience with load testers has not been good although newer versions may be safer. Still why bother when a cheap digital volt meter will tell you all you need to know.
By actual measurement from two different on the water tests a C30 at top speed draws about 18 amps. MK says 30. If you call them up they will tell you 30.
I suggested the AGM because he said one battery was dead.
I was trying to be helpful based on tears of experience. I wasn’t trying to get anyone’s shorts in a knot.
