Alarm woes

[madmacmcmad]

I have a GTO3. When I arm the alarm, I get the usual chirps, then 3 tones. The LED flashes 3 x in quick succession. Then after about 20secs the alarm goes off.

This points to a dodgy sensor. I have checked them all making sure that all circuits are broken (not completed to ground). It seems the alarm is permantantly in test mode.

Any ideas ???

Does anyone have a pdf of the alarm manual. So that I can check the operating modes.

I have pulled the alarm units apart and checked all connections and plugs and all seem OK. However, there is no led on the sonic sensor module. Does this matter ?

I can drive the car, but am unable to lock it without the alarm going off, so not ideal

Many thanks
Andy

If you have the 160 alarm then this manual is a rebadged 160

Thanks very much.

The fault appears to be at the relay from the door switches to the interior light. I have temporarily sorted it tho. I need to find the relay that controls the interior light. This curently does not work and I suspect is the route of all my problems. Any ideas where it is ? I do not think it is either of the relays in the footwell ans all cable colours are wrong.
