Hi,
I am hoping someone can help me with a puzzle I am having about the turn
signals not working. I struggle to diagnose electrical problems.
The turn signals on both sides of my 80 Spitfire stopped working. The
hazard flashers also stopped working. All of my fuses are okay and
things on the same fuse as the turn signals work.
Knowing that the turnsignal and hazard flashers both run through the
hazard switch, I pulled the hazard switch several times and got it so
that the hazard flasher would work part of the time - the turn signals
still never worked.
I got the hazard switch and cleaned each contact. Now the hazard
flashers work reliably. Turn signals still don't.
There appear to be two power wires going to the hazard switch. Purple
had power all of the time and green when ignition is on. If I jump
between the purple and green, the turn signals work. With the jumper
removed they still don't work.
It looks like the powered green wire comes from the voltage stabilizer.
There is continuity between the voltage stabilizer and the green wire in
the hazard switch.
So, I am at a loss.
The turn signals works when the purple and green wire are jumped. So, I
have ruled out the switch and the relay.
The fuse is fine.
The lights all light up appropriately when using either the hazard
flasher or jumped turn signals. So lights and grounds seem to be okay.
There is continuity between the voltage regulator and the green wire at
the hazard switch. Though when I check for voltage at the green wire,
there isn't any. I expected voltage, but not sure how there can't be
since there is continuity with the voltage stabilizer and there is power
to the stabilizer.
Any suggestions on what the problem is? (besides my lack of electronic
knowledge :))
Thanks,
Roger Elliott
