My GPW Eats Ignition Switches

I'm getting ready to replace the toggle type ignition switch in my 1945 GPW for the third year in a row.  I'm not sure what the first one was but I've had both MV Spares and Joe's Motor Pool replacements.  If I put a jumper from the (6V) battery to the battery side of the coil it starts right up.  Aside from the ammeter there is nothing on that circuit to cause a problem.  The MV Spares wiring harness is less than 5 years old and the ammeter appears to work as it should.  Anything else I can check while I'm waiting for the next replacement?  Based on past experience, as soon as I replace the switch I'll be good for another summer driving season.

Jim,

FWIW, I tested the two switches I still have and they show about 1.5 ohms resistance each.  I got a new reproduction switch today and went to put it in and one of the electrical studs fell off.  I was able to push it back on and start the jeep with it in place.  So, not a big fan of the reproductions.  I'd love to find a NOS or take-out to see if I have better luck.
