Title: Indicator Light relais
Post by Icey on 05/09/20 at 03:51:29

Hi all,

I bought a 95' savage a couple of weeks ago and it has already been built to a bobber. Now the previous owner('s) have removed the indicator Light and I want to put them on again, on the back side only. Now the cables are still present and the indicator also works in the tank indicator. The lights work but they do not flash. Should in my opinion be a relais problem, but I'm having difficulties finding the relais or how it should be wired. Probably an easy fix, but for me as a newb especially on electrical systems quite a pain. Hope someone van help me, perhaps with some pictures

Thanks in regards!

Do they turn signals light - but don't flash?

If so - a single light bulb may not create enough power draw to cause the flasher to function. You may need to replace the flasher module with an electronic one.

Seems like having front turn signals would be a good idea.....how are folks in front going to know you are turning - are you going to use hand signals while trying to operate the clutch and throttle and front brake?

Yes, the Light bulb does respond brightly, but does not flash. Where is the flasher module and what does it look like? And do you know what Electric module i'd need?

The flasher relay ,is square and mounts in a rubber holder on the right side of the bikes neck hidden near the front of the gas tank,just above the decomp . You can use one from an auto as the two blades that form an L shape will plug in even if the relay body is round instead of square[timestamp=1589033026]

I think that you need two bulbs at every side to make the thing to work. or other resistans. WTF there are small nice indikator lights to buy.. and did you know, its a good thing to let those in front of you know what you want to do/turn or others.

What do you mean by being able to use one of an auto? And yes, of course it is best to have all four on, but for now I wanted to prioritize the rear ones. But what you are saying is that all 4 indicators need to be connecten in order to have a functioning circuit?

The flasher relay tends to be load sensitive , your rear flashers should work but will flash at a faster rate of speed.

Well im no expert, but my father is an electrian, he told me some things, befor he died.
In any case, old time was electro mecanical and the mecanical parts did som clicking sound.
Soo i got out in my garage, put in the key and started blinking.. no sound at all, its electronical for all that I understand?
And then to the lesson from my father.. electronical blinking systems need resistanse.. like two bulbs. And other lessons from my father the elecktrian, I put LED lamps in some of my home instalations.. it didnt work!
Lesson learnd, old time transformators need resistans, they are marked from 20 and up to anything.
LED bulds need Zero transformators.. there are nearly no resistens att all.
In any case, it was a shot frome the hip, it could need two bulbs, for resistans to work properly?
And my advice is that its more importante to get the indicators in front of your bike!
Soo, no klicking sound, its electronical.. it need some resistance like two ordanary bulbs.. its probably a high resistance realay?
This can be examined if you are a litte handy, put some clips.. I call those as crokodile clamps to the back turn signal wirings and to a second bulb, t0 see if it helps!
In any case, put the indicatorl amps in the front.. so cars dont drive out in front of you!

The mechanical flasher has a bi-metal strip, and when it gets warm one side expands more than the other.......and this causes a set of points to open and the circuit is broken. When the metal cools the contacts come back together and the circuit is once again completed.

If you don't have 2 bulbs with filaments, there is not enough current to get the flasher sufficiently warm to operate properly. Most times there is not enough heat with a single bulb, and the relay hyper flashes.

You haven't told us if the rear turn signals you are using are LED units. If they are....they may not be pulling enough current to even cause the hyper flash, and they may just be running steady as a result.

You can jump to the 5 minute section if you just want to see what is inside the mechanical flasher - however if you are not familiar with the entire process it might be good for you to watch the entire thing.

An electronic flasher doesn't rely on the current or load, and it operates at a steady flash regardless of the type of bulb or how many are attached.

Yes so this is the one I bought. With 2 Light bulb needed, you guys mean the Lights on the front and on the back? Problem is, I couldnt find or tracé the cables on the front of the bike just yet, so I might need to make my own or rewire the cables on the back to the front. Ill dig into the electrical relais information aswell and might order a different relais.

That light is 10 Watt, which is a running light intensity - not a turn signal brightness. It may not draw enough power to run the flasher.

The original 1157 rear bulb had a 8 watt running light, and a 27watt turn signal. The original front bulb was an 1156 and had 27 watts.

Your flasher was designed to operate 54 watts of turns signals and an indicator bulb that I believe was 3 watts - so you have replace 30 watts of power draw with a 10 watt single bulb, and the flasher doesn't work properly.

The 10 watt light you are using for rear turn signals won't be visible in daylight. Perhaps you can keep the housings and install a bulb with more wattage.

Okay, ill try replacing the bulbs with a 27 watt bulb. Though it is weird, because the indicator lights do respond brightly, only they don't flash, it is constant. Making me think it's not a Light bulb problem, but a relais problem.

Mayby you got it right, but now you got some explanations howe it works and some trouble solutions!
I stand att its a totaly electronical relay.. ther is no klick sound att all.. we dont need this att bikes, we cant here it in any case!

Try the two bulb to see if its working.

In any case, dont care that much about the rear signaling.. put it in the front of your bike!
Im not only a son of en electrian but alltso a long time biker.. IE about 20 years ago but anyway, those behinde you seldom gonna drive you over,, the problems is those cars and driver in front of you!
Put the turning lamps in the front for góod sake, for your own healt!
Those in the back,, is for to be polite, telling those after you wat intension you have.. so they dont drive over you!
