Looking for factory COLOR '62 wiring diagram

[swharris]

4 way flashers/hazards stop working when brake/lights are applied. The truck is a '62. Speaking with Greg Noble at the last OCTO, he mentioned it might be a ground/pwr incorrectly wired at the speedo causing the turn indicator light in the speedo not to function. I need to sort that out but am tired of craming my head upside down and too lazy to again pull the tray and speedo. Eventually I will....I think. haha.

One last post/update to all my electrical issues. It turns out some knucklehead PO put a BEETLE fusebox in my bus. Yeah, it is only obvious when you pull the panel out completely and then can see the difference between the bettle and bus connected traces on the upper side of the box. Both boxes can work, but the wires will be in different places to get everything to work AND obviously if the beetle one is in, the wiring will not match up with the diagram. If you have odd issues or wires that seem slightly off from where you think they should be, check that the box is a BUS fuse box! Finally I hav an electrical system that is functions almost 100%. Still trying to figure out why the flashers stop when the brakes are applied and why the indicator is on the speedo is not flashing.

Really doubt that early of bus would have a 1500cc engine. Still, just for fun does it have the 1500 air cleaner bracket on the left ceiling of the engine compartment??

Ok, a day late but here is a link to a photo dump of what's going on under my dash like I mentioned last week. https://photos.app.goo.gl/haxQFdMyMjQrjg9bA .
The symptom is no turns or flasher operation and no dash indicator.

Frankly, it looks a hot mess under there, but maybe they all do. Without a correct color road map I'm at a bit of a loss but back in '11 when I got the truck back on the road including adding back in a turn signal switch (WW) and the required flasher I got it all to work with the exception of the speedo indicator.

The fuse box is pulled out just due to me poking around trying to see what goes where. That one odd ball with the plastic connector cover is the wiper hot and I'm replacing it with a correct brass connector.

I'm not sure why I'm just now noticing this but there is another "flasher" or relay that is mounted in front of the passenger. Rectangle with 4 terminal(87,87B,20,85). It is a VW part with a PN of 211 953 191. That comes back as a "flasher relay" in old classifieds here on Samba.

Anyway, for anyone interested in looking at the photo dump, go here

A reminder that this is a '62 SC.

Some were asking what the build date of this bus was and turns out it is late Dec. '61. I just went out again and took a pic of the M-plate. The decode is below. I found this bus in a body shop on Hollywood blvd. in Hollywood back in '11. Looks like this has been an LA bus all that time and it was optioned with a tilt and bows...cool. I wish I had some....extra money to get them back on. Eventually. Also optioned with dual treasure chest doors.

To confirm your statement swharris, yes 62 had wiring that doesn't match the online Diagrams. I ran into that on my june62 with flashers. I need to get around to finishing my altered color diagram.

He means 'a red knob, which doesn't light,' and not 'red knob and no light'

So the progressive refinements seems to point to late Nov/early Dec 62 as when buses got a dash hazard light above the wiper switch. I don't know if making the knob red with letters 'simplified' the circuit, so can't say that doesn't refer to something else. Any Spring 63 owners want to chime in?

Still no start date for the system as a whole, but Ithik it's discussed in the forums somewhere.

As far as power for the speedo indicator, in 61 it comes from a keyed circuit, so if a hazard system works with key off the wiring would more resemble 63. And since there isn't a pod switch, it could be powered straight from a fuse, or elsewhere like maybe a wiper switch. Do 62 wipers work with key off? :) Power can't go straight to relay as it's a K, ground, from indicator bulb, not 49a.

There can't be many of these transitional buses out there, but that's all the more reason to puzzle out a wiring diagram for them. Some people obsess over SO-42 screws, some obsess over dash wiring...

Progressive Refinements dash light entry in the Gallery:

1964-65 have a red colored knob with no light.

You posted this in the past in another thread with a good pic of the red knob:

[70bus]

I never found a start date for the system in general, but
Date introduced
29 Nov. 62 -15 Dec. 62

Emergency light (USA)
Now: Control light for
emergency light (M 24)

is the time frame each model apparently gets the dash flasher, OR a lighted knob. Or both?

And

6 Apr. 63
17 Apr . 63
19 June 63

Flashing indicator relay
6 and 12 Volt
No w: Simplified control system

could mean the t/s relay, because the hazard circuit certainly ISN'T simplified!

After June there are pages missing, so no clue if there's more detail later.

Anyways, you folks know more than I, but that's what I was able to dig out of Prog Refinements
