Tail Light Turn Signal Issues
I have an older ERA....
Lights OFF: I'm not getting a 'flash' from the right tail light (right turn signal) (left is fine). Lights ON: both tail lights do come on, but no 'flash' from the right or left tail light. The front turn signals work fine - light off and on. _____ Does this sound like strictly a wiring issue or are there parts to be checked, also? Any input will be appreciated. |
You have my condolences. If you feel like reading, these two threads explore just about every tail light turnsignal failure mode imaginable. Patrick gave a lot of hints and trouble-shooting tips throughout in them .
Also, Bob's Electrical Primer troubleshooting guide is very helpful. I think you can access it from their website. I will try to find it and post a link. http://www.clubcobra.com/forums/era-...n-signals.html http://www.clubcobra.com/forums/era-...ems-782-a.html Dan |
Here is Bob's electrical troubleshooting guide. Since you have an older ERA you may want to give him a call once you have done a little troubleshooting.

Thanks, Dan - especially for the condolences.
Lots of info on those threads. |
Patrick - bulbs switched. No variance.
Also, The old and new left rear bulb works fine in the right rear socket - so, there is something up with the left rear flash circuitry, plus the circuitry on both sides (rear only) when the lights are on. BTW, nothing is easy for me. Thanks. |

Agree with checking the ground. When I built my car I disconnected the grounds to install the carpet and forgot to hook them up - similar symptoms to what you're describing and easy enough to check.

Thanks for chiming in. |

Are the mentioned fuses separate from the array of fuses attached to the firewall inside the engine area? |
Quote:
What ERA number is your car? Perhaps the really early ones didn't have the fuses. I'll check the schematic for your car number and see. EDIT -- It looks like they put the fuses in around car 335. |

Here, I did a five minute cut and paste on your car's wiring diagram so you can see what you are dealing with. Since your front flashers work, you know that your signal wand switch, and the flasher unit, are both probably working properly. Your brake lights and signal lights use the same filament. So, from that, you can surmise that:
1) If your brake lights are working normally, then you know the connections from the trailer relay to the rear bulbs are good, including the grounds. 2) If your brake lights are also misbehaving, then it could be either the trailer relay, or the connections between the relay and the bulbs, that includes the grounds. You will need to test the voltage, using a VOM or test light, coming out of the trailer relay, on both the yellow and green wires. If those readings are good, then you will test the wires as they go in to the bulb fixture itself (note that it appears the wire colors change). If we have to, we'll also check the wires going in to the trailer relay and maybe use a 12v jumper wire to test the bulb circuit itself. The way you will check the wires is to carefully scrape a little bit of the insulation off of them, using a razor, so that you can see the copper conductor. This is really not hard at all. If I had to guess, I think it's going to end up being either a bad trailer relay or a bad connection (that includes a ground). http://www.clubcobra.com/photopost/d...8_flash001.jpg |

The front lights also have two filaments, but since there are no "front brake lights," it doesn't matter and, thus, needs no relay to sort it all out. |
OK - forgot for a minute there the three modes of operation at the tail.

Trailer Relay - These units are apparently available at auto stores - is there are top choice product or will any one do just fine? BTW - you sure are being very helpful - thank you, thank you very much! |
