Hi Gentlemen,
Just found this forum while trying to troubleshoot a Legend AEAD 200 LE SN JH 313273 which wouldn't rev up when arc was struck on an intermittent basis. Found your board and got info to replace the 6 terminal idle module which we did(Miller Service said same thing). The old one fell apart on removal, we replaced with a new one and all seemed fine. My friend took off to do a job and the battery was low and old so they hooked it up to a 12V battery in a nearby truck. Welded fine all day yesterday. This morning they find it has no spark? Any suggestions on where to look now? Though we had it beaten with the $94 module but now another problem. Any help would be appreciated. Thanks,
guzda and (Pete)
