Turn indicator & brake light continuous flashing, Started with a bad bulb Options

[bzettner]

'73 1.7, driving along (IMG:style_emoticons/default/driving.gif) both dash turn indicator lights and brake light started flashing continuously (IMG:style_emoticons/default/WTF.gif) . Found out I had a burned out turn signal bulb. Did my 914World searching and learned the flashing is to "let you know" you have a bulb out, great! Changed out the bulb, flashing continues. Cleaned light socket contacts, bulb ends, changed out bulbs in matched pairs, replaced flasher unit with new RockAuto unit, still continual flashing. Added a little brake fluid, no change.

All my lights work as designed, all of them. Dash turn indicators are bright and work individually when used. The new flasher unit causes the dash indicators to flash continually dimmer than the original unit.

I have found a white w green strip wire near the flasher unit that has no connection, no fitting, just a blunt cut wire with no obvious "answer" to its placement. I am NOT a great schematic guy (IMG:style_emoticons/default/headbang.gif) . Something changed! Ideas?

Update, I dug and found the other end of the white w green wire, connected and the flashing brake light stops (works like its supposed to) The wiring diagram shows that wire going from the light switch to the speedo. I certainly don't see it going into the back of the speedo. Not sure where it ends up as it nestled well in the dash harness.

Still have the continuous flashing turn indicators in the dash. Everything works as it should except the flashing indicators.

The brake light you talked about is the indicator in the multiple gauge correct? Was this wire broken or cut on purpose?

The original "flashing condition", while driving, included both dash turn indicators flashing WITH the brake light flashing. When I got home I "played" with the E-brake switch and added some brake fluid, though it was not really low. The brake light quit flashing at that point but the dash turn indicators continued, even after the faulty bulb was replaced. The next drive, it took about an hour before the brake light started flashing again.

The WH/GR wire appears to be broken or cut. I can't imagine how the wire could be cut/broken. I found the other end of it in the wire bundle behind the gauges, temporarily joined the ends and the flashing brake light stopped.

Yes, the flashing brake light is in the multigauge/brake light/gas gauge. altenator light/oil pressure light
