Jud,
When you switched the P-leads and the problem did not shift to the other mag did you do the P-lead switch at the mags? If you did the switch at the Mags you might try swiching the P-leads at the switch and see if the problem shifts to the other mag switch position. It sure sounds like you have eliminated evreything (rebuilt mag, runs good with no P-lead, and new switch) except the P-lead.

Re: Mag Troubles
John,
I did switch the p-lead at the mag, so that would be one way of trouble shooting the wires from the P-lead back to the switch I pressume. I'll keep that in my bag of tricks...

Re: Mag Troubles
I've lost track of what you did and did not do. Lets start a new thread so we are can follow what you really did and the result rather than what we think you did with different results. 
Besides this thread is at page 5 and very few threads are any good much after page 5.
