Hi all,

On tuesday after we;d done the spring PAE has developed a new problem...

I was just wondering if anybody can think of something I may have touched that could cause this...

When the interior light is switched on the horn goes off and vice versa ( it makes no difference taking the bulb out, or whether you're using the doors or the switch in the dash to operate the light. Also operating the horn will turn on the interior light if the bulb is in!

I can see from the haynes book of lies wiring diagram that the interior bulb and switches run from the same fuse (along with the clock which doesnt seem to show anything odd going on).

I realise i probably need to go round with the voltmeter - but thought i'd post here in case anybody has any 'illuminating' ideas that dont 'honk' so much ;)
(sorry...!)

Cheers,

Rich
 
Yes, it's all battery control. At least people will know it's you hooting as you'll be spotlighted too. :LOL:
The clock only winds from the circuit which is instantaneous so might be too quick to interfere with anything. What happens if you push the cigar lighter in?
 
:)

Just had a look at the parts pages on the rover classics site and looks like the light on the wing and the horn wiring join very near by. Given the sellotaped 'joints' we found i'm guessing we could have disturbed another of these. Definitely one for the soldering iron i think!

Can't beat nicely soldered joints & heat shrink-tubing. Though the lightings on a different circuit from the interior lights aren't they.
 
they *should* be on a different circuit but I'm pretty suspiscious of the loom in that area... bits of tape and connectors which arent original. It's work till we touched the sidelights on the wing so got to be a failure of sellotape... thats where my money is anyhow ;)
