Loom with a view - expunging a datatool alarm

[KitchenSync]

I've stripped out the hamfisted installation of my wonky datatool alarm - but I'm a little iffy about two points that I can't tell whether they are standard or not.

shows where I'm at. There's a zener diode in that green wire and two separate green and red wires spliced together. I've got the wiring diagram somewhere but it's quicker to ask if these connections are standard. if not I'll remove the diode and separate the green/red wires (are they indicators?)

Fanksh!!

Can't be too much help. I'm afraid, but I too de-datatooled the blue Falco, nobody died, the bike still works and I'm no expert with electrics. There was a similar electrical component in one cable, and I just left it there. I did make a point of stripping out every wire that had been spliced into the main loom, and then covering it in heat-shrink.

The only reason I can see for that wiring arrangement for the indicators (If that is what they are) is so they can all blink in unison at you when arming the alarm. I'd be very tempted to trace all three cables back to their origins and strip any one lead that is superfluous. If one wire is spliced into an unbroken cable, remove the interloper, trace it to its end point and remove it there also.

It's basically a fairly tedious process of reversing all the additions that the installer made.

I spent the afternoon doing the very thing wot you just mentioned. Why on earth a professional installer wasn't heat shrinking everything astounds me - I unwound about 3km of gungy black tape.

I don't imagine the diode will do any harm left in place but I'll see if I can isolate those two (presumed) indicator wires assuming they've not been snipped.

.... though probably best not to post up too clear a pictorial guide of how to remove an alarm ......

I'm nearly done with this now...

Just tidying up to do - info is easily available elsewhere but here is a summary (from elsewhere):

"I used to install datatool alarms, they are hard to tamper with when the bike is in its normal state and armed. They have a mercury switch, two imobilisers and they sometimes have little switches under the seat which triggers the alarm if the seats removed.
But if your not nicking the bike and have the key etc then they can be easily removed.

They seem alot more daunting than they are. you just have to reverse the installation process.
This is the part where you pray that it hasnt been installed by an absolute monkey that was lazy and threw the alarm in. :roll: If its been fitted well you will have alot of soldering to remove and thats pretty much it.

the two imobilisers will be hard wired into the loom at two seperate places, i think we used to use the starter relay and igniton switch, (hard wiring is where the wire your joining the alarm to, is actually split and joined to two new wires, rather than soldered on to)

you'll have to melt the solder off of the two new joins and reconnect the original circit,
(if there isnt enough original wiring to rejoin then you may have to replace the parts you need from a breakers, easy bits to pick up)

there will be an earth strap hopefully clearly attached to the frame with a ring terminal to and existing bolt, remove.

A live wire will also be attached into the loom on the battery side of the ignition switch usually. again rewire or remove solder depending on installation.

The indicators will have wires soldered to them, these are simple to remove as there soldered on.
if time has been taken when installing, then they will be running inside the loom and you may need to unwrap and re-wrap this.

It may or may not have a small trigger switch installed. usually installed under the seat, easy to spot. (very small white box 30mm x 5mm ish, with metal strip on top)

the alarm box itself has a 9V battery inside it, put the alarm in service mode and remove this (you'll need a 'security star bit' t-bar of socket to split the box) remove the live wire for the alarm and this battery together, this will cut all power to the alarm allowing you to work on it without losing your hearing.


A haynes manual (the wiring diagram) will be really helpful. Take time with it, be methodical and it should be straight foward enough."
