I have a weird problem with '79 Transporter... Parking lights, tail, instruments, and license plate lights will not turn off, the key is OFF and out of the ignition.

Here are some things I have tried:

pulled all wires from light switch

pulled all wires from emergency flasher

pulled plug off ignition switch

pulled all wires off coil

This happened sometime after I replaced the foam seal around engine, but I don't know if related to my issue.

Yes they do go off when I disconnect the neg. battery terminal... Anyone had this problem? H E L P !

If it still has FI then you most likely have a ground issue. There are a few grounds in the engine compartment, double check them all, clean them to shiny.

Check your fuse box for corrosion or water damage. Couple screws and it pops out to see the back side.

Take the emergency flasher apart (carefully) and check for water damage. You should be able to get one of these at a FLAPS.

Thanks, water on fuse box is possible, I will drop the fuse box and check the flasher relay next. When I turn on flashers, right rear blinker flashes alternately from blinker to tail light, all others normal. This might be a clue but i am yet to understand it.
