Speed Four & Datatool Nightmare

@Blanketstacker Welcome to the family. Hope a fellow patron pops along soon to help you out. Me I knows nothing.

 

My son and I had a similar problem with a 600 Yamaha Fazer many years ago.
A rather drastic solution but we found the simplest way to resolve the alarm problem once and for all was to replace the whole wiring loom with a secondhand one.

Probably not what you wanted to hear but its a complete solution as when the data tool was originally fitted the wiring would have been extensively modified to make it difficult, if not practically impossible to remove.

 

Wherever the alarm fits into the main wiring loom, it should just unplug, and then you replace it with one of these, which you should be able to get from your Triumph dealer. I did this with my thunderbird, with no problem at all. They call it a blanking plug.

 

The blanking plug would be the simple solution if the bike had originally been fitted with a Triumph Datatool alarm. However in the OP's case it appears from the photos that the alarm fitted was wired into the loom rather than using the OBD port, (if the Speed 4 even had that port fitted)
That means rather more drastic measures are required to remove the alarm in this instance.

 

That's not so good, can't help you with that one I'm afraid.

 

@Blanketstacker You should be able to unwrap the wiring and remove the alarm that way. you may need a soldering iron to melt the solder on the wires. Then just tape up and do a reset.

 

I'm sorry I don't know for certain if the looms are the same but I doubt it.
The looms will be different for a carbed bike and one with EFI.
It might be possible to remove the alarm as Joe McDonald has suggested but you will need to be very careful in reconnecting the original wiring.
The Datatool alarm splices into the wiring loom specifically so it is difficult to remove. You will probably need some spare wire and be good at soldering, plus the wiring diagram and make sure that you connect the same coloured wires together.

Best of luck!!

 

Hi and welcome to the forum, I can supply you with a genuine new Triumph blanking plug that Bikerman shows in his attached picture, it will be £10 including postage, if interested PM me.

 

If you bare the wires and remove the alarm manually you may indeed need the blanking plug

 

Am no wiring expert. Daughter and husband bought a used 2022 Nissan Juke that had an aftermarket remote start installed.

Immediately, the battery kept going dead due to that unit. Her husband took the car to a place that installed that kind of product and had them remove it from the system. Pictures of its removed black box showed a horrific web of wire. Technician (older gentleman) was excellent. No more dead battery.

My 2 cents: if it ain't from the factory, forget it.

 

The datatool alarm on my old Sprint 1050 was wired in the same way. My alarm had gone completely mad and disabled the starter button so I had no choice but to rip it out.

I had a wiring diagram and a meter and was able to do a continuity check on the wires to figure out which were 1,2, 3 and 5. Connect those together in pairs then the other wires can be ignored and blanked off.

Sorry, I can't help anymore than that and good luck.
