Electronic box pass saddlebag

[888GoldDragon]

Hello everyone, I bought a ‘94 1500 SE. it has a electronic box in the Rt saddlebag, no markings but take a round key. Any ideas what this is. Much appreciate any help.

I would guess an alarm of some kind. Sure has a lot of wiring connected to it. What does it look like inside?

Couple of mini relays, I’m not very good with electronics.

This is 100% an alarm system. The giveaway is the two chips on the bottom left. Next to the thick grey cable is a TBA 2800 which is a linear amplifier for receiving infrared signals, and the chip next to it is a TEA 5500, which is an ASIC designed for decoding infrared signals to lock and unlock alarm systems. I suspect the grey cable leads to an infrared photodiode receptor that is positioned somewhere on the exterior of the bike.

So this alarm likely had an infrared keyfob that would have been used to arm/disarm it. The fact that it has two relays indicates that it COULD also have an immobilizer component to it, so be careful when removing it, as it could render the bike unable to start. If it were my bike, I would trace down all the additional wiring that hooks this thing to your bike, and excise all of it, returning the bike to factory condition.

Thank you very much that’s what I was afraid of but I will start searching all the wiring.

Didn't the seller tell you about it?

This alarm seems to have a European origin.
I think it's an old model of the TSS GROUP company. Maybe they can get you more information.

No unfortunately the previous owner past away and a friend sold it for him, knowing nothing about it. But thanks for the info, I will check it out.

Used to service a Honda VTX1200 for a friend and he kept complaining how it would stop on very hot days.
Turns out it had an immobiliser he did not know about and obviously never used - carefully hidden above the engine and the excessive heat would cause the unit to shut the bike down until it cooled down.
Had to trace a spaghetti junction of wires back to source connections to remove it. All good after that
So take your time and all should be fine.

It’s All gone, thanks everyone for the information, a little time consuming but we got it stripped out of there.
