2003 Dutch Star, 350hp Cummins, 3000 alison, spartan mountain master chassis, plug the adapter in under the dash and no lights, so started the coach and still no lights. Brought it home and hooked up the usb and the lights work and the ipad could see the adapter.

I have not tried the one in the engine bay yet, I know it cannot make the 40 feet to the ipad, but will try that just to see if the from diag. port is knackered.

Anything else to try? I am supposed to flip the switches next to the diag port?
BTW- got the green adapter.
