Alarm system removal?

Hi. I have an old Patrol Line alarm system that disables the starter when unplugged. The system is faulty and I want to remove it.
I have partially removed it by cutting the + and - terminals to the siren. I have also removed the cable that messes up indicator lights when used too many times during a ride. I can fire up the bike, unplug the alarm system and the bike will still run and act 100% normal. But when I stop the bike and try to fire it up again, it won't start (i hear a clicking noise from some sort of relay, when pressing the starter). I have to reinsert the cable to the alarm box again.

No major problem in living with this, but as you riders can understand, real estate is scarce in the seat compartment.

Any help is greatly appreciated!

I tried this too. I even contacted the company that sold the alarms but I couldnt get it working so I bought a used loom instead - problem solved. It was really cheap too around 40 euros.
Took an evening to swap it out, its not very complicated.

It's simple trace the wires from the starter button to the alarm/ relay then bypass it back to stock that's all that's done when they installed the alarm in the beginning was break the circuit...
All it is stock is a hot wire going to the starter button (when ignition and kill switch is on) and a wire to the starter solenoid and when the buttons pushed closes the circuit and powers the starter... All they have done is made the wire go to the alarm/relay instead of the solenoid easy fix honestly

Simple as a multimeter and testing wires from the alarm could figure out what ones from starter button and what one goes to the solenoid... If you know what your doing

:stpd: The majority of alarms require you to cut the starter wire in half. If you trace back from the alarm brain it shouldn't be difficult to repair the connection. Just cut out the alarm and solder the starter wire back together. I'd be willing to bet it's the the thickest gauge wire running running out of the alarm brain. :thumbup

Ok, thanks! When the alarm is unplugged and everything is ready to fire up, then when I press the starter button I can hear the fuel pump engaging as I press the starter button. If I let go, it stops. If I press it again, the fuel pump starts again, but no crank. Wonder if it will start if I push the bike and put it in first gear.
I'm not an expert with tracing wires, can this narrow down the problem? If not, I have a friend who is an electrician (not on 12V systems, but we'll give it a try).

Thanks again all!

I don't see why you wouldn't be able to bump start the bike... But it really does sound like a simple start relay... Like stated above, it's likely the starter cable has been cut... If you want a sure fire way to find out... If you can pull up the wiring diagram for the alarm and find out which wires are going to the starter... If you have a multimeter one of those wires will show 12v when you press the start button the other won't (with alarm brain unplugged). Think of it as a "key side" and a "starter side" you cut the starter wire and essentially turn it into 2 for the alarm to function properly and thus preventing the bike from starting when the alarm has been triggered (basically "cutting" that starter wire). All you need to do is make it back to 1 wire. Do you have any pictures of the alarm?



Edit: I'm not even sure that makes sense :lol I hope at least some of it does :thumbup

- I tried to wire the red and black cables together (the ones going into the alarm box, if you check the picture). That only fried my 5amp fuse for the tripmeter/clock. I thought this was for + and - to the starter relay.

- Rode today with my Ducati friend, and he noticed my indicators were flashing all at once when my bike hit a bump. I wiggled the alarm box, and the indicators would flash again. It is in really bad shape and I want that infernal thing out of my bike.

- Found the manual for the alarm online. Got some pictures from it here. Hope you guys can help me out, that would be gold!

Ok... Sorry, I was gone for a little while... It looks like (DO NOT DO THIS WITHOUT TESTING WIRES AND BEING 100% SURE.) you can take the green/black wire and white/black wire and test those. They should be the 2 wires that are connected to the starter... If they test out the way they should and you can verify they are indeed the wires "cutting" the start wire you can simply solder those 2 wires together and that should give you the start and basically bypass the relay not allowing the bike to start because of the alarm.


If you do that... You should be able to just unplug the alarm brain and be fine... I'd personally trace every wire hooked up and remove them from where they were originally spliced just to be safe though. I've done tons of alarms on cars that had previous alarms installed, and it's always a coin flip as to how the original connections were made, how they held up, if they were correct to begin with, etc.



Edit: P.S. Don't touch red to black... Ever.
