1975 914 brake light/turn signal question....with video!, Update: Video added...see latest post Options

[billh1963]

Started working on getting Mark's "BB" ready for Okteenerfest and have started sorting a wiring issue. The turn signals weren't working and after replacing the turn signal relay and turn signal switch to no avail I figured it had to be the flasher switch itself. After replacing the switch (thank you Dominic), I know have hazard lights and turn signals. However, I now have the following questions:

1. I have a burned out right turn signal bulb. Will that cause the yellow turn signal indicator light on the tachometer to stay illuminated? (see picture) I don't have a spare at the moment to see if changing it solves the issue. Current;y, it stays on

2. I don't have an owner's manual. What is the other light on the right side of the tachometer (not illuminated)? It does not illuminate

3. I replaced the turn signal relay with the Wehr brand relay. However, I am still getting the buzzing and fast blinking on the brake light that has been attributed to the relay. I have read that the emergency brake handle and/or needing to reset the MC pressure switch will cause the light to illuminate. In my case, the e-brake handle is down so I will try resetting the MC switch tomorrow. Anything else I should take into account that may cause this condition?

Thank you
