As usual in my time of need I turn once again to the experts. I am recharging the dead magnets on the '14 which have grooves on the back from the flywheel ridges. Do i flip every second one when charging and if so do I install them n,n,s,s.
"T"hanks to all:
Flip every other magnet when charging. Charge them so the north poles remain the north poles and the south remain the south. When installing them, the north poles on go together and the south poles go together like you have stated.
Index the poles prior to any attempt at charging as they need to be charged in their original orientation - better yet, bring the Mrs. down with you for a garage tour and I'll charge them for you while you wait ! I did Chico's.
