Thought I would use my Late 66 series one to go out last night. It hasnt been on a night drive for some months. Car started fine but no sidelights or headlights! Indicators and brake lights work. Anything to do with side lights/headlights e.g parking light, headlight flasher nothing happens. My first thought -a fuse must have gone but there is no fuse for the sidelights/headlights. Switches still have a nice postive feel. Car has standard 4 fuse box negative earth RHD cloth covered loom. Any ideas please?

Hi,
First thing to check would be whether you have a 12V feed at the switch, either with a multimeter or a test lamp. If yes, the fault is likely to be in the switch itself. If no, it's probably a dodgy connection and you'd need to trace the feed. I'm not familiar with Series I's..but I think the lighting switch feed is a brown wire from the terminal post.

It's fed from the regulator box. I lost the feed to mine recently & had to run a bypass wire to get it back.

SirD66 said:Thanks for the replies. I would like to try a bypass. After removing the handbrake gearlever console and the centre console I have better access to the rear of the light switch... The wiring diagram for RHD with neg earth shows a control box with letters DFWBBE for the feeds. I have scanned the diagram and blown in up to A4 size so i can follow it. My box has different numbers...please see the pic. As the colours on my loom are very faded I am not sure without dismantling the loom which does what. Anyone know from the pic which one is the light feed wire please? I can then try a bypass. Many thanks. with lights fixed i can book an MOT and get car back on the road
If it helps I came across this on the Holden site...it's for an RB106 regulator but the wiring may be comparable.
I'd hazard a guess that the DFWBBE on your wiring diagram would equate to D,F,WL,B,E on your RB340 regulator. But don't quote me on that!
Good luck!

Been there, done that. I'm still flummoxed that the original feed wire would be damaged as most of it's in the loom & it isn't that long.
