Flashers on go-slow

Hi All,

My indicators recently started working very slowly and are now staying permanently on rather than flashing. I gather from using the search function that this is likely to be the flasher itself. I saw on another thread http://www.classicroverforum.com/viewtopic.php?f=16&t=10809&p=83235&hilit=flasher#p83235 that these http://www.ebay.co.uk/itm/FIX-INDIC...10?pt=UK_Motorcycle_Parts&hash=item5198db75a6 will be a permanent fix. However this has two pins, and PAEs flasher looks like

.

Does anybody know of a similar device that would replace the 3 pin lucas flasher, or do i have to replace like with like?

Many thanks,

Rich
 
Hi Rich,

I am pretty sure that mine only has two pins, both the original Lucas rectangular metal can and the generic replacements. The replacements proved to be far more reliable too.

If you pop into an auto store, they might have a three pin job, but I dare say most if not all will be two pin devices these days.

Okey doke - ill get the Lucas unit I guess. Ian might even take one to rugeley for me :)

Thanks for the candid advice as always :) I mist owe you a fine English ale or 3 by now!

My Haynes book of lies shows the relay as different between three thousand fives and series 2s.

Lucky is running an electronic flasher unit - but then he does have LED flasher bulbs! My understanding was that you caould get electronic ones with an adequate switching capacity to cope with tungsten bubs as well. The key advantage is that the electronics controls the time interval between flashes, so you are immune from the P6 slow flash syndrome.

BUT the cause of the slow flash is not necessarily the flasher unit. It's more likely to be a poor earth somewhere in the system. And the most likely culprit is corrosion on the back of a light unit. But then none of us want to discover that, do we? So by far the best plan is to try changing the flasher unit first!

Sorry Dave, nothing to do with the alternator. The flasher unit consists of a relay and a capacitor. After many years of use the capacitor can start to give problems, with either a longer time to charge or a lesser one. The result being the indicators either flash very slowly or very rapidly. In both cases a replacement is the order of the day.

that was my thought - The voltage regulator isnt playing a part here as engine speed seems to play no part. If it was earth related it'd expect some variation in behaviour, but right turn now means solid orange. left turn means solid orange. Looking at the circuit diagram the flasher circuit affects both sides equally where another fault would only affect one side. Will find out in the morning when i get to rugeley and try the new flasher unit :)

I thought they were a bimetalic strip that heated with the electrical load until it flips over and disconnects, then cools and flips back, reconnecting the circuit. That's why if you lose a bulb they slow down due to a less current flowing.

However I'd go for an electronic one everytime these days.

Hello Richard,

Well seeing the OEM units came from Lucas in 1960s or 70s, anything is certainly possible. The unit that I am currently using is a clear plastic cylinder with the relay and capacitor visible inside, so I just assumed that the Lucas items would have been the same.

Ron.
 
OK - so it's not working right after driving it... Going to swap the relay for the other one they supplied just in case! otherwise, maybe they aren't equivalent in all senses afterall... The lights work but the flashers on the dash both flash and the relay makes some funny noises...

Rich.
 
Hi, the fact that the dash lights are both on could mean the fault may lie in the hazard
switch as that is where both side come together. Try working the hazard switch in and
out a number of times and twisting both ways lightly with or without switch cleaner.
Because the switch is so little used the contacts fur up and it only needs a touch to break
any continuity. I have had problems with them before.
