Weird Turn Signal Help

[JP6210]

Hi All- I am trying to troubleshoot my 76 Westy- having some weird turn signal issues and looking for some direction-

Right turn- blinker light and alternator light come on- no lights blinking on exterior.

Left turn- blinker light comes on, blinks fast and lights on exterior blink fast.

E-flasher- nothing happens when I pull the switch. Have checked all the grounds...I think.

The difference between left and right is what is really confusing me-

Thanks for any help!

weird stuff happens when the hazard switch pops open. zip tie closed after you are sure it has not popped out springs and what not. Reach under the dash and feel the hazard switch box. feel like its still one piece?

Eswitch seems ok- nothing obvious open/broken. I did take the opportunity to make sure the connections were solid. Next step for me is to follow the Bentley and do the turn signal switch test, the relay test and the eswitch test. Unfortunately, I have been slowly working through PO hacks in the wiring and trying to bring things back to where they should be-

make sure you don't have a wrong type bulb in there somewhere, and your contacts on both bulb and bus are looking good.

A fast blinker almost always means I have corrosion on a bulb somewhere in my bus. Check and clean all your bulbs, and check the tail light ground connection to the body of the bus (it is on the right side of the engine hatch) This connection gets loose and corroded over time and has the same effect as corroded bulbs....

Check the fuses...I had all kinds of strange things like this going on. They can be hard to see, especially for me...takes lots of light and the strong glasses I wear for watching Matlock. Sometimes those fuses are broken and it's hard to see. Sometimes they look fine but don't work.

[JP6210]

So...current state:

Have checked all the fuses, and actually replaced with the correct ones in a few cases. Ignition on, pre start, alt and oil lights go on, then out when the engine starts. I still need to check and see what happens with the ignition on and the right signal. But some new symptoms have developed- right turn now blows the fuse. And, while checking I seem to have fried the relay- puff of magic smoke and the lovely Taiwanese relay the PO had in there bubbled and filled my bus with a really unpleasant smell. New, proper relay on the way...


In the meantime, I feel like the turn signal switch itself does not feel smooth- hard to describe other than it feels a bit crunchy- My self cancel function has never worked so I plan on taking it out tomorrow and examining it closely. It passed the Bentley tests, but... And my horn does not work.


And I am still suspicious of the emergency flasher switch- it has not come apart, and passes the Bentley tests, but seems like there are a few failure possibilities there. If the rain stops tomorrow I will trace current per the diagram- I have 12V to the e switch, and from the switch to the relay. Ground checks out at the relay for continuity. I tried jumping the relay, from the white to the other positive contact, in the absence of a relay to continue checking voltages down the line, but that is when the fuse(s) blew.


All of that would seem to point me towards the actual turn signal switch. Maybe...

So- turns out crunchy feeling in a turn signal is not a good thing...

Replaced today and cleaned up more connections, replaced a bulb and turn signals and hazard switch are working as they should. Thanks for the suggestions and help!

And one more FYI... I purchased a new emer flasher switch from BD at the same time- the shaft for the original knob, does not fit the new switch- so, either verify the size or order both the switch and the knob, and I would still verify with BD that the two they sell are compatible.

Happy Holidays all-

So- new symptom... Flasher and signals all work as they should. But now when I start the bus the dash indicator blinks and I can hear the relay clicking without the flasher switch or turn signals turned on. It is somewhat sporadic and there are no outside lights flashing when it happens. It does not seem like there s any voltage on the white wire that feeds the flasher relay when it happens. I’m a little stumped. Any ideas or direction would be much appreciated. My limited electrical knowledge says that it must be back feeding from the turn signal switch but the switch is new, and operating correctly. I guess my next step is to see if I can unplug the turn signal switch when it is happening and see if that stops it.

Hi Folks- bumping this up to see of anyone has any ideas around my turn signal dash light and flasher operating with ignition on but no emergency switch or turn signal on. I have checked the e switch and my turn signal switch is new. Signals, and emergency flashers work as they should and there are no lights flashing on the exterior when this happens. Thanks!

How big a wattage is your arrow bulb in the fuel gauge?, does it still click constantly if you remove the bulb?

Yes, the indicator bulb.

Is there power to the fuel gauge and idiot lights when the key is on?, the flasher could be trying to feed that circuit through the indicator bulb.
