wiring confusion re indicators on 70 US bay

[fredster]

Hi all,

Having difficulties (putting it mildly) with indicator wiring. Basically, hazards work, indicators don't.

No 12v signal going to little indicator arrow lights on dash. Can anyone tell me if little green arrows should flash when hazards are on on a 1970 US bay? - This will help with my detective work.

As hazards work (flash at correct rate) would that suggest flasher relay is ok? My suspicion is that indicator switch is at fault but not sure how to test it. Are they available new? The wiring doesn't look messed around with much, all fuses are good and earths are good.

Right, well they are flashing now. Annoyingly, not thru any actions of mine, just a loose connection somewhere. To add to the mystery, the indicators also now work but green dash lights only light for the first flash, then dash lights stop but idicators themselves keep flashing.

These electrics will be the death of me...

Are the flasher relays for 70 USA bus still available? Me thinks they might be a tad rare.

I fired mine and half the dash wiring when trying to sort it out, once the professionals got hold of it they fitted a modern relay but even my dash light does it's own thing still.
Good luck :roll:

Hiya Fred,

USA spec 70 Baywindow................

The turn signal indicator lights in the dash should light up when the turn signal switch is activated. Mind you, both (left and right) indicator arrows will flash for a turn. That your turn signal indicator lights only come on once (but your relay keeps the actual turn signal lamps flashing) indicates a relay on its way out. The relay (if original) that you should have is a 211 953 215C. Here's a picture............

The 215C relay was used in all VW Type 1 and Type 2 vehicles in the 70 production year and is not terribly hard to find at swaps and shows. I prefer to use the original relay rather than the aftermarket replacement because the original was made to plug into the fuse box. In any event, given the symptoms you have described I'd try replacing the relay.

Aftermarket replacement turn signal switches are available for this application. They tend to be very expensive and they are somewhat generic in that they are made to fit a number of years of Bus production when the originals were unique to each year. I have collected turn signal switches for parts and used them to "remanufacture" good switches. Works very well for me and is not nearly so costly as buying aftermarket. Original VW quality and fit to boot.

This is the actual switch........
