No adjustment eh, one switch, seems to be a 2 stage switch, any test to check card ? And the sevcon controller meaning including the card or the whole assembly? Would a switch throw the code, This has been going on for a while, Mostly seems to be after charging, I take it apart, mess with it, put back together, works for a few weeks, do it all again, If I knew what to order for parts, would be a lot easier Appreciate any more insight on these blasted things
