Posted: Sun Sep 16, 2007 4:51 pm Post subject: Magneto Installation

Am wiring up a Slick 4375 on a 7A.  I am finally straightened out on the

wiring per Bob's diagram Z-13.  My question is should I see infinite

resistance across the P-Lead and ground when the switch is open or am I

going to see zero ohms because of the points in the magneto?  Any input

would be appreciated.



Thanks

   The DC resistance looking into the p-lead of a magneto

   is VERY LOW whether or not the points are open. This is

   why you need the electro-mechanical or more modern electronic

   "buzz" box to sense the AC resistance of the magneto.



   Short answer is that for most meters, the input to the

   magneto p-lead port looks like a dead short all the time.
