Thanks to the previous owner, nothing was wired correctly - switches/relays/fuse box etc. I now have headlamps/high beam/low/flash thanks to a new relay and correct wiring. I have also replaced installed (there wasn't one there) the hazard relay, I can indicate L/R but no hazards when I pull the switch. I have part number 211953235A - but is missing terminal 58b (according to wiring diagram) which is supposed to be for dash light dimmer (?). 1979 USA Type 2 Westy. Have the po's installed the incorrect switch? or is mine just buggered? Cheers *any typos due to fingers warming back up.. tis cold I tell thee.
Terminal 58 connects to the instrument light supply. On the hazard switch, connecting this up makes the switch glow at half-brightness at night, so you can see where it is. Believe US busses had to have this. If the connection's missing, won't affect operation of the switch - look elsewhere PS If you're buying a new switch, get the Brazilian one with this terminal fitted (has a small resistor on the top). Worth having!
Ta. I stumbled upon this earlier http://www.coolairvw.co.uk/Item/Shop_by_Vehicle~Baywindow_Bus_Products~Bay_Bus_Electrical_Products~Bay_Bus_Gauges_and_Switches~Bay_Bus_Switches/211953235A/T1_65-83_-P-_T2_68-79_Hazard_Warning_Light_Switch.html You can see the resistor ... I could try bridging the switch? *off to look over wiring diagram.
That's the one! Best to work through the wiring, mebbe take the switch off & test continuity through the contacts. I think the diagram shows its innards.
I'll update you Saturday.. Too cold and not enough light to be trying during the evenings. Posted some links for anyone that may have similar issues.
