urgent info needed regarding indicators stopped working

Rolandtheroadie

Recently removed an alarm/immobiliser from a motorbike, which although probably easier, should be much the same.

I'm assuming as it's an aftermarket one, any alterations will probably be in accessable areas.

I just picked a wire, and traced it back until I found a connection (on the bike all the alarm wires were black, so I eventually came to a coloured one).

Kept that seperate, then traced another black wire till i came to a colour.

When I'd got two the same colour, I joined them together.

Perhaps google the name of the system (if it can be identified) and try to get the pincode of the plug coupler so you can concentrate on the indicators.

If you must continue driving in the meantime, the law requires you to put a warning sticker on your vehicle to tell other drivers that your indicators are broken. You can print out your own using a template from here.

An auto electrician once confided to me that around 90% of all electrical faults could be traced to a "bad earth".

So, on that basis, I would be inclined to identify the location of this aftermarket alarm system, identify how it is "earthed", and verify the integrity. Chances are it may well be a loose or oxidised contact both of which are easily remedied.

I appreciate the alarm is disabled - I am just working on the basis (suggested by AA) that the indicator / hazard warning earth (or power) pathway has been modified to route via this device in some way.

Obviously the issue may be caused by something entirely different but this is how I have always started my automotive electrical troubleshooting endeavours (after checking the fuse and relay).

Identifying the location of the aftermarket alarm should not prove too difficult. Assuming you know your way around - they tend to look slightly "out-of-place" in my experience. Additionally, they are sometimes marked with their brand name (e.g. Invader 2000).

Ultimately, as the alarm is out of use, in the long term, removing it completely is probably the best option. Have some spare wiring, assorted connectors and a roll of insulating tape available when you do undertake this procedure.

I would be removing the alarm
a dead alarm isnt something you want sitting in your electrics
unless its been a full pro install,it should be fairly easy to trace its wiring
find the alarm box/siren or whatever type of unit it is(i assume no siren if its affecting the horn)
remove the wires one at a time with the battery disconnected
after removing a wire,reconnect the battery and ensure the engine starts etc
ensure any wires left are insulated with tape,heatshrik or whatever
I know this sounds slow,but for a novice its far safer than having a car that doesnt start and no idea which wire caused it.
If you find a cut wire (as in an imobiliser circuit)
ensure the wire is re-joined well(solder and heatshrink is best)
with this type of job a methodical approach is best
