no turn signals- help

[ragtop man]

okay I have a 1970 bay bus that has no turn signals at all. I have traced the wires for the turn signal switch and all of them appear to be correct. I would like to know where to start looking. I have just cleaned all fuses and the fuse box to make sure I was getting all the juice to the correct places. my headlights work but no high beams. when I touch the contact points together there is a small spark, but no change in the headlights. I have power to the copper bracket on the turn signal switch when I turn on the headlights, but nowhere else on the turn signal switch. please help, thanks!

first place I would check would be the relays. they like to fill up with water.

the flasher relay is '70 only' and get kind of hard to find. you could have a bad switch another '70 only' but others can be made to work.

I will check them out. I have one little square one that is SWF
there is a black square one that I am almost positive is after market.
and then I have a big square silver one with rounded corners.in the middle.

can you tell me what each relay is for, thanks for any help!

is this bus new to you or have you owned it for awhile. Did they ever work when you owned it?

The turn relay is J2 here, which one of your relays has the same color wires going to it?

The headlight relay is J here, same deal, which of yours has those color wires connected?

busdaddy, I just checked and I have the correct color wires in the fuse box but it looks like they are in the wrong place for the relay to engage them all. there is a double brown wire in the fuse box that is not plugging into the turn signal relay due to it position. and the blue wire is the same way it is in the fuse box but does not plug into the relay due to where it is in the fuse box. the blue and double brown wires are not connected to the relay. I hope this makes some kind of sense.

[ragtop man]

just checked the headlight relay and the wires at correct on it.

[busdaddy]

How many wires are on the back of your emergency flasher switch?, 4 or 9?

just noticed the turn signal relay is a Wolfsburg west relay. I am removing the wires from the fuse box and putting them in the correct place as per the wiring diagram. I will check the hazard switch then, thanks for all the help so far!

[busdaddy]

Good plan, it's always easier to figure out if everything matches the diagram.
But do check that hazard switch, there's 2 different systems around that time and you'll want to make sure you are wiring for the correct one.

okay just got through connecting the turn signal relay back up per the wiring diagram. now when I turn on the passenger or right turn signal and both front turn signals blink, but no rear signals at all. the emergency flasher was not working but now it makes the two front turn signal lights flash but still no rear flashing. oh yeah I do have a signal light working in the speedometer with the turn signals and the emergency flasher. what do I look at next?

[busdaddy]

[ragtop man]

just pulled it out and it has 9 wires. that is including the ground wire on the side of the switch

[SGKent]

before you tear into the front any further, use a VOM to check for voltage at the rear when it is flashing. It could be as simple now that you could have a bad ground back there.

okay was just cleaning the grounds up in the back. when I move the turn signal to the left or drivers side it flashes all 4 lights just like the flasher does. when I move the turn signal lever to the right or passenger side turn signal there is nothing. flasher is now working as it should.

[busdaddy]

Tell us more about this WW relay?, any photos?, what's the part number on it?
A 9 terminal hazard switch means your bus uses a 3 or 4 terminal flasher, if someone has attempted to install the 68/69 unit you'll be beating your head against the wall.

[ragtop man]

it is a four terminal flasher WW 211953915C flasher

[busdaddy]

Sure you don't mean 215c?

If that's what you have then carry on, so far the parts seem compatible and it is indeed a 1970 style system, now we have to find the PO suprise or bad ground.

when you say "nothing", you mean no lights or the lights just come on and don't flash? Is the car running when you do this?
