Had a tether kill switch put on trike. Now its blowing all the bulbs when you throttle it . They r telling me its the rectifire.. Never did it before they put that tether on there any help thanks

 

sounds like it's dead shorting when it's not supposed to. Wonder if they happened to use a headlight ground as part of their kill circuit? My thought is that it should almost be completely separate. like it shorts the coil to ground, very simply and keep the other circuits out of that kill loop I've also heard that a bad ground is hard on the light circuit all by itself without any modifications.
