.......J-case (3 main fuses in there) one was part of the recall BUT there was another that wasn't part of the recall and caused my slingshot to shut down on me on the NJ Turnpike while I was in the left lane, talk about an OH SHYT moment.........check that J-case (especially the rear of it )......
.....My fix was to separate that 2nd fuse in that J-case just like the one for the recall, haven't had any issues since ......so that left me with just one fuse in the J-case.....
Good advice, but would that explain the white smoke? Wait, only the shop saw white smoke. Scanman , if it were me I'd listen to Funinthesun and Dave@DDMWorks and dig deeper. Please keep us posted. I'm smelling a skunk.
