Lektrickary problems

[boomer]

i've just taken another squizz at 'em and its only the gaffer tape thats melted; the actual unit hasn't deformed at all.

So MR ixion, i believe your onto it..however these things need to be relocated if thats the problem to somewhere as you state and the gaffer tape removed. They're currently sat under the pillion seat on plastic, which ain't good


i woudn't have expected 'em to get soooo hot tho ..

cheers Ixion !

As Ixion says, the resistors you've put in are to simulate the load the 20w standard bulbs would have. LED indicators don't have this load, so you need to add a dummy load else where, hence the resistors.

The heat is normal, as you've discovered, the resistors can take it, just your tape doesn't like it.

What can you do?

Mount the resistors with something that doesn't melt, somewhere where the heat isn't going to melt anything expensive like fairing.

or

Get some resistors of the same ohm rating, but with a heavier current capability (wattage). Probably an arse thing to find.

or

Replace the stock flasher unit with what they call an electronic flasher unit. It doesn't give a shit if there's any load of not, it just flashes the same rate all the time. They're about $30 from just about anywhere, and easy to fit. Fit that, and you can ditch the resistors all together.

or

Attach some small heatsinks to the resistors with some araldite. They'll give the resistors a larger surface area, so the heat gets spread around. They'll still get hot, but as the heat is spread about, the whole heatsink/resistor will get up to less temperature. You can get a heatsink from any computer geek, or from Jaycar/DSE. A bit of pissing around, but no lecky knowledge needed.


I'd go option three myself.

Oh yeah, you could always just strap the resistors to the subframe, which would be like attaching a big mother heatsink. As the subframe is huge, it can handle that little heat load no worries at all. It should be able to dissipate that heat sweet as. Just strap them as tight as you can to the subframe. Try some cable ties. If it is able to keep the heat down enough, they won't melt. It's the easiest and cheapest to do, and you probably have cable ties... try it and see how it goes, might be problem solved.

Any luck?

Just got PM.

Just buy a bigger wattage resistor would be my guess, skim read it only though.

[Dafe]

Definately just replace the resistor with a higher wattage of the same value.
Unless the module was intended for multipurpose usage. Just replace the resistor with a rheostat and mount under your seat. Presto - Seat warmer!

Led flashers require a different current, and what is happening is that there is to much erectricty ( trying ) going through the slow the flashersdown thingy

Dont know your bike/layout colors ,, but the thing to do is work out how much electicity those LED use ( written on box ,,Watts ) , then this will give u the current ( Amps ) ...then you need to put a resistor in ( R ) before the slowtheflasherdown thingy ( the thing that is melting )

Just remember Watt/Are xVirgins and Virgins/ Are x Rare

You can but new Smoke from any Lucas agent,,,,,,

how come those threads offering the same advice have Just appeared !!! Doh ....and much better at that ,,,( I thought it was the flasher unit getting hot and there were no resistors in the circuit ....

[boomer]

cheers guys,

teh flahers came with the tail tidy and had no box/packaging to speak of. i'll be buggered when its WOF time next.

As for the resistors, i may go buy a big ass mofo one from ... i'll hunt around.

but i've attached teh current ones to metal which is dispersing the heat nicely. I just need to remember to switch of indicators

cheers all!

There MUSt be someone who can help me;

The problem is,(long intake of breath) the flasher system is designed to flash at the correct rate when 2 twenty watt bulbs are connected to the flasher relay.
Because the replacement LED lamps are less than 1 watt each, you need the resistors to draw the same current as the 40 watts of the original bulbs.
of course these resistors need to dissipate 40 watts as heat, which is not easy.
So you will have to arrange some kind of heat sink and provide it with airflow.
Or,alternatively,find a 'no load' flasher relay to replace the original.
I've seen these at supercheap for around $30.Someone said they found them for $5, but I think they must've been on the drugs.

Still gotta get rid of 40 watts,regardless

[Ixion]

Bigger wattage reistor won't reduce the amount of heat , just ensure that the heat doesn't blow the resistor up (as Mr Pixie observes) .

[boomer]

right, now we're getting places. I know why, how and what to do to fix it.

cheers guys, i'll save ma money and use bag ties to attach to them to the sub frame.

[davereid]

Ya only got to use the indicators for 3 secs.. so just do that and dont spend a cent. Find corner, push button, go round, turn off indicator.

There is an indicator that indicates when your indicators are indicating. Its all you need.

[gammaguy]

get down to Jaycar or Dick Smith and grab yurself a heat sink,mount box to it and preferably somewhere in the airflow.Should sort it I had to do the same to the Reg/Rec on my TDR.
