    most alligator clips use piddly tiny wires with a fat insulation jacket to make it look like gauge. They are also usually just crimped down which may not make a good connection. Maybe put a molex plug on it to plug into mpu j4 or replace the wire in the gator clips and terminate them better than how they come when you buy them.

    Quoted from oldschoolbob:

    Not much shop time again today. Tonight I installed C5. Made no difference in the voltage. Then I moved my 5 volt clip to the left side of L2 (that would be the same as J4 pin 16 and 17). Still no difference.
    Then I inspected the alligator clip and wire. Andrew was right. Small wire and large insulation - plus the wire looks like it's just bent down and crimped with the insulation. Crappy test leads. I may try to solder the wire to the clip but that won't fix the wire gauge. And I can't take the banana plug apart to inspect that end.
    Any suggestions on where to get a decent set of test leads. I think I got these from Jameco.

    Thanks

    Yeah there is no way that alligator clip could handle much current. The termination is literally stripped wire folded back under the insulation jacket and then crimped down. If you want to stick with alligator clip leads replace the wire. Crimp the insulation jacket and solder the wire leads to the gator clip. Use a fatter gauge of wire.

    I am pretty sure the gator clips are made that way just to be cheap and the fat insulation is just a way to make them look beefy when they are actually cheap ass thin wire.

    I wonder what the metal teeth of the gator to a PCB test post current rating really is. I don't see anywhere where they rate the current of these things.
