More to the story....
I went out today and wrote out a kind of trouble shooting matrix. It is here...
Turn Signal Info At this same link is the turn signal wiring diagram. I have wired it exactly. As the stop lights are a three bulb light (stop, turn, running), I connected the turn signal wire to the turn signal.
The wiring harness is from LMC equipped for the turn signal installation, the turn signal a generic from the same vendor. I have confirmed time and again, that the correct wires have been connected.
The trouble shooting matrix might be a little confusing, sorry for that. It appears that:
1. Four way flashers seem the only thing working correctly, except that it is flashing also the brake lights. Normal?
2. Anytime the rear turn signals work the brake lights are on too.
3. All lights seem to work at one time or another, so I can't imagine a grounding issue.
Could the turn signal itself be bad? Do I need some other relay in the mix?
Thanks for anyone willing to take a look.
