Flashers on go-slow

So ... question is do we have any lucas Gurus on the forum?

My original lucas relay has 35020 written on it, which seems around the web to be referred to as FL5/SFB105 and GFU2103.

Looking at the teminals on the bottom of the relay i've been supplied, instead of B P L on the 35020 the one i've got says X P L and the only markings on it say 12V 21Wx2+5W and 057. The box is marks as BM parts but there's nothing on the box to tie it to the part inside... (basically i'm wondering if a) this is the same relay, and b) if the part that's in the box matches the box!)

Thanks,

Rich.
 
Done a bit more research now...

B P L and X P L terminals are the same. I've swapped to the other relay they sent and that works better although it slows down after the first few flashes which isnt right so i think these cheap flashers arent what they're cracked up to be.

B or X is 12v supply.

P feeds the warning lamps

L feeds the indicator switch.

So from this I think i'd be OK to go for something like this:

Thoughts?

The electronic flasher unit looks like a much better proposition Rich. As you say, the others look like duds.

Having had a look round the net, I cant find any electronic flashers rated to 42W - so I'd have to change to LED bulbs. Has anybody found any higher rated ones anywhere? The spare relay they sent gave up the ghost after 5 minutes of driving.... so i'm now indicatorless. Thinking of putting the original relay back in as at least it works with a steady bulb, where these 'new' ones are flashing very quickly and making odd buzzing noises...

Thanks,

Rich.

It doesn't make sense. All 90's cars had electronic flashers and normal bulbs. Something new generic from you local shop will do the job, as well something used from a breaker.

I think the problem is that the 90s cars arent using the 3 pin relays to flash the lights in the dash. They seem to have a +,- and a single output connector for the light itself...?

I guess in this case the dash lights are fed from the normal indicator circuit after the switch in the steering column.
Still doable if you are not afraid of being a little creative with the wiring.
 
Yep :) If nobody knows any better then i think the easiest way is to go LED... for the sake of £20 on led 'bulbs' and £5 for the relay...

would be nice to just change the relay though considering i've not had a single bulb failure in my time with PAE...

I could be completely off here; on our old 83 Peugeot 305 (RIP dear car!) I noticed when the indicators were flashing, the indicator light on the dash was on when the outside yellow lamps were off, and vice versa. We never changed it's flasher unit, so I can't think of whether or not it was a similar unit with 3 terminals or not.

I'm not sure of the Astra we currently have.

I'm just wondering if the 3rd pin is the "opposite" of the 2nd (i.e. when the 3rd is live, the 2nd isn't, and vice versa)

Just a thought!
 
I've not managed to find a correct circuit diagram for 35020 or 35010 ( which is the same with screw terminals...)

Hi Colin - maybe I'm being thick here but i dont think PAE has hazards?

Hi, apologies I didn't realise PAE was a series one. That will teach me to read posts properly.

How about trying an electronic towing flasher which automatically senses and adjusts the
flash rate for the extra load? They are designed to replace the existing can.

The fourth pin is for a light to show a trailer is connected, which if you don't have you could
omit.

:) I actually went outside and searched the dashboard before i wrote that reply... I was worried in case i had managed to miss the switch for the hazards!

Rich
 
Right. I had a look into the wiring diagram for a series 1 car with a 3 contact flasher unit and it seems that the dash warning lights are actually fed straight from the indicator switch like the other front and rear lamps, but instead of being earthed somewhere, their return line connects to the flasher unit again. It's a Light Green Purple wire. Weird.
On later cars with the 2 contact flasher units (type 8 FL) the warning lights are simply earthed.

SO, i guess you can just fit a 2 contact flasher unit and just earth the LGP wire. You just risk a blown fuse, although even this is highly unlikely.

I guess you must have spent some quality time in my country!

Yep... We got married in Crete and have been a few times so I know my Greek alphabet and all the tourist lingo :)

Well I've bit the bullet and ordered an electronic flasher and 4 LED bulbs. (Tried halfords first but they wanted £15... per bulb!!!)

Rich.
 
All installed but not working. Too dark to go round with the voltmeter now though - one for tomorrow or the weekend!

The LEDs did come on steady temporarily on the old relay, so I think the LEDs are fine and have mailed the relay seller in case they have any advice...

I got these - can anybody see anything I've overlooked?
