Cyclone V2 alarm niggle

[LordShaftesbu...]

I have one of these on both my bikes:

https://www.motorbikealarm.co.uk/node/47

The one on my Street Triple was installed at my local dealer's. It was all working fine for a while but now the alarm status indicator light on the instrument panel no longer flashes when the alarm is active. The alarm itself still seems to be functioning though. I took it to the dealer's and they said they couldn't see why it wasn't working (they were sceptical it had ever worked in the first place, despite them fitting it ).

Before I go off and spend £275 on the horrendously overpriced Datatool alaram, can anyone tell me if they can think of what to check or how to get this light working again?

I realise it might seem extremely trivial but I would like to have the warning light functional as it's yet another deterrent to add to the list.

In before all the "If the want it they'll have it" etc. etc.

The status light is only an LED. You can unplug it near to the alarm unit, and just stick a different LED on there, to see if the problem is with the long lead that the LED is attached to, or the unit itself. Personally, I'd suspect the lead.

Of course, so simple ... now why couldn't my dealer have thought of that?

I take it it's a trivial matter to find and unplug that one cable?

Now to buy an LED ... do you get different types? For example, do different LEDs take different amounts of juice to light up?

[LordShaftesbu...]

*cogs turning*

I suppose I could use my multimeter to test the voltage the long lead supplies and make sure the LED I get will light up with that amount?

Although if it measures sufficient voltage then maybe I don't need an LED at all?

Tell you what, if you can't get any this weekend, PM me your address, and I'll send you some on Monday.

I emailed the company that sells the alarms, no idea what to make of the reply.

[nowhere.elysium]

To be honest, I didn't find him to be spectacularly helpful when I spoke to him on the phone, about an unrelated issue.

The ECU will have no bearing whatsoever on whether or not the LED flashes, so I have no idea what the hell he thinks that he's on about.

Do you have a digital multimeter? If so, plug it into the red lead that's running into the back of the LED. Arm the alarm, and then watch to see if the voltage blips between 0 and 5v. If it does, then the LED's dead, or the lead's been damaged. If it doesn't, then there's something wrong with the alarm internals.

This is the alarm indicator light that used to flash (this is the Speed Triple panel but it's similar).

I meant for the bike - they've usually got a general breakdown of what wire does what on the dash.

My owner's manual certainly doesn't, but I've found a workshop manual:

https://www.torrkish.com/triumph/Workshop%20Manual.pdf

[LordShaftesbu...]

These pages from the workshop manual appear revelant. But I've still no idea what I'm looking at.

[nowhere.elysium]

I've had a look through the service manual, and the wiring diagram I was originally after was on p256. However, the breakdown that you linked to tells me that the wires you want to try attaching the red lead to pin 3 on the plug, and the white lead to pin 2. Both of the leads that are going into those pins are black, which is rather unhelpful. They break out to the Triumph alarm socket (which I'm presuming is still present in the loom), to pins 11 and 10, respectively.

The problem here, is down to the way the Cyclone was originally fitted. It looks like the Cyclone's Warning LED has not been used, but the bike's built-in warning lamp in the instrument cluster has been utilised instead. You need to find out how this was done, by asking whoever wired it up.

Your copy of the Cyclone wiring diagram doesn't show how the Warning LED should be connected, but there will be a dedicated 2-pin connector for it, and one of those will be a permanent earth. I suspect that whoever did the wiring-up, took the live side of the 2-pin connector to wherever the header plug from the instrument cluster comes out of the loom, rather than solder it directly to the back of the LED inside the instrument cluster.

If you can find the 2-pin connector at the Cyclone end, do what nowhere.elsium suggested with a spare LED - if it works there, you can trace the red wire from there to where it joins the bike's original wiring.

Well, after poking around for about 5 secs the fuse blew. So now I need a new one.

It's a blue blade fuse with the number 15 on it, presumably that means 15 amp?

Although I have found that my last picture is partially wrong - that red and black lead is in my installation, it's just that everything's been wrapped in so much electrical tape I never noticed it before. From the alarm unit under the pillion seat it heads off in the direction of the tank, presumably the mysterious "loom" resides somewhere there ...

[LordShaftesbu...]

Well I've just bought these so hopefully they're the right ones; they look right anyway.

The fuses arrived and I replaced the blown one. Everything working again except the dash LED. I stripped the red and black wires coming from the alarm unit and measured the voltage with the multimeter - completely dead. This suggests to me that the problem is with the alarm unit, although I'm going to buy some LEDs and test using those just to make sure.

If it is the alarm unit I don't really want to replace it as the actual alarm and immobiliser parts are still working. So I found an alternative solution:

Not sure if this has already been suggested. But you can remove the LED mid-way down the wiring - where the little plug disconnects from the main alarm wire.

If you have two alarms, why not just switch the two and see if they work on the opposite bike? It'll be a quick case of disconnecting and putting it on the other alarm and seeing if it flashes?

That way you can work out whether the problem is the wiring, or the LED?

If it's been suggested/done already - I apologise.
