Re: MOT Charging reactor



Original poster: "Arpit Thomas" <arpit-at-inzo-dot-org> 

on all the mots if taken appart, the windings have not been interleaved. i 
grind the welds to a little below the surface, then smash the I loose with 
a chissel and small sledgehammer olaced where the welds were. works like a 
charm.
