Flasher Can

My turn indicator on the dash has an intermittent fault - no different to that :-). I have traced the fault back to (I think) the flasher can.

As a new "can" is $A142.50 and I'm not _certain_ that it's the can (aren't intermittent faults a pain) I opened the can today for examination.

The internals, not surprisingly, are largely surface mount components (of which I'm not familiar). Examining the board I can see some slight discoloration in one corner where three identical (linear?) components are. They have the code "152" printed on them. Other commitments will prevent me from doing more on this today, but I would appreciate receiving some feedback on what those components might be and if it is relatively easy to remove & replace surface mount components using a conventional (temperature-controlled) soldering iron.

The Flasher Can has LR Part No. PRC8878. If anyone has any information on this unit, I would appreciate it (I have the factory workshop manuals, but not the ETM).

In the UK, you can buy one from Halfords, an OEM equivalent, for £16, but then the Land Rover one is only £26. One of us could always mail you one (not me, I'm going away!)

IIRC from the part no, it sounds like yours is the black 5 pin type for use with towbar electrics.

God, how sad am I? A year ago I didn't even *have* a Land Rover! What have you lot done to me?!

Hi Dave, Yes Dave, that's the unit.

Hi Jeff, Interesting! Ron Beckett (who replied on our local list) suggested a capacitor (based on the code), however he did't claim any expertise with surface mount components. As for shape, as you postulated it is a rectangular prism rather than a cylinder.

Thanks also for the advice to look further.

FFS! that's bloody pricey, even at a (guessed) 3 a-bucks to the quid.. I hope it plays the correct national anthem while the indicators are working...

mind you, the one on the 110 is clever enough to know when it's got trailer lights in circuit and flash the little trailer on the dash. Disco (1995,

110 is 1985) has little trailer light too, but doesn't flash it. WTF is the point in that?

I suppose I might get around to investigating why, one day.

If you get a meter on it, you should find the resistances are in line with the code that's printed on them (use a digital one for best effect). With this particular circuit, this appears to be true for all resistors, ie there are no other parallel components dropping the resistance. So you can test them all without removing them.

With correct configuration, trailer light is supposed to flash just once whenever the turn indicators are operated (in order to show that it is still operating). Do you:

1: have the correct flasher can to operate the trailer indicator, and/or 2: have a blown trailer dash light?

Good info, I was concerned about that possibility, not having a schematic and not being enthusiatic about drawing one.

Thanks Dave, Peter '93 Disco 200Tdi

No you don't - we've got too many of you buggers out here already. :-)

Re the always flashing: Have you any extra turn lamps over original? I'm not sure if I posted the information to this group, but I had the same issue, due to the "extra" indicators in my ARB - until I fitted relays to operate them.

Everything's completely standard, no extra flashers/telltales or anything. Works fine with a trailor connected.

Just one of those things, been like that for the last 5 years....... Anyway, she doesnt look at the dash, so it doesnt matter!

Looking at the Flasher Can (PRC8878) it has two lines:

  1. 12V 3x21W +5W
  2. 6x21W + 2x5W I infer that 1. is front & rear lamps, side repeater & dash, and that 2. is essentially hazard lights operation (both sides at once). At some point greater than 68W (3x21W + 5W) and less than 89W (21W added for trailer lamp), the unit activites the trailer lamp repeater on the dash.

It appears that you are drawing more than 68W when you activate the turn signal.

Bull bar indicarors can cause this. Try lower wattage bulbs in the bar if you have one. I had the same problem when I had a bar fitted to my 130. If you don't have a bull bar with indicators, sorry I don't have an answer.

Apparently there is also a special flasher unit that can compensate for the bar lights too...
