Stupid questions about motorised conveyances

Fitting LEDs to previously incandescent-equipped circuits probably screws up current drop detection. That's a Hooli guess, though.

That's cause they need an electronic timer type flasher unit, so it's not dependant on load. Traditional flasher units either just don't work or flash really fast with LEDs.

LEDs are lower resistance so might be affecting things. Put proper bulbs back in and see if it behaves.

My vectra had Cambus and a self check of lights. I fitted led bulbs in that and every so often the car would strobe its sidelights when parked up!

LED bulbs act differently. I fitted LED indicators to my CBR1000 and when one failed I didn't get the other one fast flashing to tell me something was wrong.

I know with indicators you have to use a different relay which is pretty much an electronic timer and they can't really differentiate if one has failed or not.

Genuine dumbass question here in regard to the above.....

On the Cowley, I have two seperate flasher circuits. One relay supplies current to the 1970s add-on flashers fitted with festoons.
Another (ordinary) relay supplies current to the trafficators which are now fitted with LEDs instead of festoons.

Both circuits share a common switch but the dash warning light is only wired into the flasher circuit, not the trafficators.

When I changed the traffs to LEDs I experienced no issue with the existing relay wired into the circuit.

Would this be because the coils holding the trafficators up are energised throughout the signalling period, I wonder...?

[Hooli]

I'd guess so, that'd give a load to the circuit. The older flasher units used bi-metallic strips that heated up with the current flow until they bent and broke the circuit, as they cooled and straightened they completed it again - hence the clicking noise.

12months MOT
"Usual scratches" I've been told

What do we reckon it's worth?

Probably a lot more than you would think, maybe even enough to make it worth sorting the paintwork

Prices are all over the place though. So difficult to figure out what they actually go for and what is the ridiculous prices that cause some to sit.

The handbrake tell-tale light in my E36 hasn't worked since I bought it, and it came with a fresh MOT which was advisory-free.

Was that a hooky MOT or is that light not tested? It doesn't bother me because I know when I've put the handbrake on, but I'm just wondering if it would be an issue come MOT time in October.

I did investigate the switch on the lever, and cleaned up the connections etc. with no success.

[mercrocker]

Think it is only an advisory on mechanically-handbraked cars and only if the warning lamp serves no other purpose. I'm sure I got my old W123 through like that but things may well have changed....
