I have a turn signal problem that doesn't seem to have been addressed previously. I have a 46 two-ton that came with a non-functioning set of turn signals. They were wired totally separate from the brake/tail light. I have installed new wiring and purchased a 7 wire turn signal unit and installed it. My wiring is as instructed except for the wire to the brake light switch, which I have not connected (since the turn signals are totally separate). The good news is that the lights light up as they should. The bad news is that they don't flash. Any ideas? Thanks for the help - I love these forums!
