So, further fun and games with the alarm system this week.

For some reason, the central locking in my usual key has stopped working. Luckily, I have a second key that works fine.

But given that the alarm unit itself had also thrown a wobbly (as per my previous post), I decided to dismantle it to see if it was repairable.

Here's the unit:

Removing the cage and splitting the case:

In the left side is a circuit board; on the right, the speaker and a battery pack. Here's what the circuit board looks like - note the corrosion from water ingress (circled) on the socket for the battery pack - we'll come back to that.

Here's the speaker and battery pack removed from the right side of the casing and stripped down. The speaker is open circuit - it doesn't work.

The battery pack looks to be made up of rechargeable cells in a rubber case - but it showed virtually zero volts. This is probably because the middle pin on the fly lead plug to which the red wire is connected had corroded and looked to be shorting with the black wire; when I unplugged it, the pin sheared away (circled, right picture)

So I decided to repair this by soldering in a new wire direct from battery pack to the socket terminal on the circuit board:

I also decided to temporarily wire in a spare speaker:

The reason? To run through the alarm country change process, so I could turn off the self-arming feature.

If any of you have done this, it requires you to press the bonnet switch in a certain sequence, whilst listening to a series of response beeps from the alarm unit. No speaker means you can't hear the response tones.

So... having done all this, I reconnected the alarm unit and found it worked normally (no random triggering); I could set and unset the alarm normally using the key remote; and I could hear the beeps from the unit so I could change the country code. Result!

I'm really glad to have got rid of the self arming setup - it's so annoying!

Now I've just to see if I can get my non-working remote to work again...

By the way, here's a link to a post on testing the central locking reciever:

Wow- is there NOTHING you can't fix??!

Total r e s p e c t !!

I can't believe you've managed to pull that back from the brink- I would have thought (despite the corroded wiring connections) that the rechargeable-cells would have become depleted and unable to accept a charge years ago; to find there's still life in this stuff is amazing-

There's a lot going on in that alarm, eh?- quite refreshingly pre-surface-mount components !

Yes, it'll be interesting to see if the batteries do re-charge after a few days back on the car.

However - it's fairly moot as I assume the batteries are there to power the siren, which doesn't work...

And I'm still not sure why the unit went ballistic last week; while the speaker stopped working months ago.

I will try re-programming my non-working key into the system, though, as having two keys with functioning remote locking would be good.

And the alarm is still serving no other purpose than providing a visual cue that the remote locking has worked...

Just to wrap up on the whole alarm thing: firstly, before re-fitting the alarm, I removed the protective hinged part of the bracket that prevents access to the wiring connectors when the alarm is installed (easy enough: two rivets to drill out).

No doubt this is intended as a security measure, but it's actually just a pain to have to physically remove the device from the car to disconnect it.

(This is pretty much my first mod for this car...!)

With the alarm re-installed, I was successfully able to reprogram both of my keys into the system again by following the procedure in the "Anti-Theft Device/Alarm" workshop manual document, pages 5-7. This only worked because some wonderful person had written the alarm code on the service book... phew!

So, alarm system and both remote keys are now fully operational again, albeit minus its siren.

I think I speak for the community,

Ha... well, onto more mundane tasks: I fitted my newly-acquired Alfa 155 black Speedline wheels and gave the car a wash, clay and polish:

Finally got round to fitting these wind deflectors today - exactly a year after I ordered them from Partsworld!

I must say-

the Alfa Romeo badging on those wind-deflectors gives them an air of legitimacy, that's hard to ignore...

Yes - they are a nice addition, for sure!

Also - my used replacement clutch slave cylinder failed last week, so I replaced it with a brand new one prior to heading down for Southern Alfa Day at the weekend. Should’ve done that first time round, shouldn’t I?

Those deflectors looked very nice. Kinda tempting me even though I wanted my 145 restoration to be stock...

well,

they are a factory-extra; so it doesn't get more stock than that!
