Hi all,

Have been wiring up relays and integrating the CA18DET loom plus some goodies into the original loom.

Is this correct light behaviour ?!

Beam (blue segment comes on the warning light cluster) only comes on when :-

1. Pull light stalk towards driver with main lights off.
2. Pull light stalk towards driver with side lights on.
3. Pull light stalk towards driver with main lights on.
4. Push light stalk away from the driver with main lights switched on.

That all seems ok to me.

Main lights only come on when :-

1. Main lights switched on with light stalk pulled towards driver.
2. Main lights switched on with light stalk in neutral position.

When I have the main lights on AND push the light stalk forward away from the driver, the main lights go off ?! Is this correct.

Apologies if I’ve used the incorrect terminology !!

Thanks, Richard

PS - CA18DET write up due soon !!

When you refer to "Main Lights", are you referring to the headlamps (both main & dipped beams) in general or the headlamp main-beam function only?

In what I think you are referring to the neutral position for the steering-column mounted, combination stalk-switch, it is the headlamp dipped-beams which operate, when the main headlamp rotary-switch is in the 2nd ON position.

The blue warning light should only illuminate when the headlamp main-beams are on. This should only occur under the following conditions:

(1) The steering-column mounted, combination stalk-switch, is pushed away from you, when the main headlamp rotary-switch is in the 2nd ON position.

(2) The steering-column mounted, combination stalk-switch, is pulled towards you, as a momentary function, which briefly flashes-on the main beam, irrespective of whether the headlamps are switched ON or OFF.

There is no warning-light / tell-tale-light (NOT blue!) on a Triumph Toledo or Dolomite for the headlamp dipped-beam function, although there are occasions when it might be useful to have one, which is why my 1974 Triumph Toledo 1300 "HL Special" will have one as part of my refurbishment & upgrade program.

I had some weird and wonderful behaviour when I installed relays in the light circuit. With full beam not working and the indicators flashing the side lights. I found that pretty any fault in the lighting system is down to one issue, bad earths.

If you have lighting problems check and clean the earths. 9 times out of 10 that will fix the problem.
