Flash rate Problems?? (Non LED) - SV650.org

15-08-05, 03:19 PM

Just fitted some motrax dinky winkas indicators on the front. now the back had small indicators on when i bought it.
now with the engine not running and when you first put your indicators on they flash normal but after about 2-3 flashes they speed up abit.. when you start the engine and give it a small amount of throttle they flash slower as soon as you back the throttle off they speed up..

i never noticed this before i changed the front ones.. and non of them are the LED type..

Could it be because of the wiring as on the standard indicators you could see which wire went to the bulb contact and which went to the surround
on these new ones i could'nt see which was which so i just assumed the solid wire was positive and the wire with stripe was the negative so to speak???

Any suggestions

Used to have the Dinka Winka, never been a problem.

Although they are bulbs they may well not be 21Watt.

Some small indicators or repeaters have 10W or even 5W bulbs. If both sets were like this it would probably be enough to put the indicator relay into the "fault" mode with fast flashing.

Check what wattage the bulbs are. You might still need some ballast resistors to get the relay load up.

And if i do need these where do you get them from and will i need four??

See what the bulbs say first, the wattage is usually (often?) printed on them somewhere.

Maplins will probably do something suitable, but depending what power the bulbs are you'll need to select the value for the resistors. You can probably get away with just using 2 of a suitable resistance, one each side, but see what the bulbs are first. If they are indeed 21watts each then the problem is something else anyway.

Okay here is the info

front

H21W
11 12

back

12V1W
11 12

now i found that the back ones are LED type so i will need some resistors..
just strange how this didnt show till i put these in could it be that the wires might be wired incorrect as you cant confirm postive with the motrax indicators??

Also what kind of resistor do you think i will need?

Cheers for the help..

so you'll need one resistor for each of the rear indicators.

Power resistors come in preferred values, a suitable standard value for each is 6.8 Ohms (designated 6R

though up to 10 Ohms will probably do.

You really need 25 Watt rated ones, in theory 10 Watt rating will do but they'll still get mighty hot. (the power they'll actually need to handle depends on the voltage applied, 12Volts on a 6R8 gives just under 2 Amps and around 20 Watts while it's actually on, but it's only on for half the time).

Probably the easiest is pop into Hein Gericke if you can, they do some "21Watt" ones specifically for the job (order no. 22001899, they are £1-99 each), saves any faffing around .

Note that they're wired in parallel with the LED, not in series. Just connect one end of the resistor to one wire, and the other end to the other wire at the indicator.

Sack it i am just going to replace the rear ones for the same as the front as the rear are a silver look so will get them all to match and it will fix the problem...

so if someone is interested in some LED micro arrows let me know...

thanks for the help though..
