Emergency Flasher Stopped Working

[srfndoc]

67 Bus with stock setup. My emergency flasher stopped working recently and I'm trying to figure out the cause. Left and right flashers still work fine both front and back. I have power on the -S terminal of the emergency flasher switch and the K terminal is correctly hooked up to the blue wire going to the turn signal switch.

Initially I thought I had a bad switch but trying another switch did not fix it. On both switches, if I pull it out half way and wiggle it a bit I can hear a single click like its starting to flash but then stops. Could my 9 pin relay be bad even if the turn signals are still working correctly? I did clean the surface where the switch mounts to the dash to be sure there was a good ground.

Thanks for any help.

When I replaced my wire harness in my bus i had an original 9 pin to use. I had the same problem so I too tried two different flasher switches,neither had worked.
I bought a new 9pin from WW and low and behold that was the culprit.

Unfortunately my bus was modified by the PO with this setup:

It looks like they used two of these instead of a 9 pin:

Maybe these will work as a replacement:

I'm guessing this was a solution somebody offered before WW had their 9 pin setup? Either that or they didn't want to pay $64 for the 9 pin replacment:

So... I'm going to order one of the $10 relays and replace it to see if that resolves the issue. Is their any benefit to going to the 9 pin relay WW offers vs. my current setup (albeit not as clean looking)? Everything has always worked very well up to my emergency flashers that stopped working.

Thanks

Hey Todd, don't mean to hack into your thread and hijack it, so I'll give you my two cents worth before I hijack.

I like the idea of the 9-pin, clean, correct. I tried like the dickens to get the 9-pin i had on my 66 to work, but ended up having someone bread board me the equivalent (down in San Diego many many moons ago). If WW had one back then, I would have been in heaven. The breadboarded hack that I had looked much like what you have with the two relays, I guess I'm not the best electrical engineer, cause I never did get full understanding of how the two relays worked together.

On to the Hijack:

Has anyone tried to fit a 9-Pin into an earlier bus? Say a 63? Currently I have blinkers, and emergency flashers, but no dash lights that illuminate when blinking or flashing. I have tried every combination of relays and used the correct wiring to try and make them work, but again, must not be the best electrical engineer.

Would it be worth it to try? Anyone done it? Have the schematic?

Damn you Greg!

No worries, I'm still trying to evaluate my options and figure out how the two relays work together as well. The fact that I still have turn signal flashers working correctly seems to prove the relay is working. It really looks like a grounding issue but I double checked the switch and cleaned up all connections but still have the issue.

Electrical is not my strong suit either so its a learning experience for me every time.

Just to bring this full circle, replacing my custom relay setup with a WW 9 pin unit fixed all my issues and is working great:
