Never a dull moment!

[Lord Geordie]

I returned from work last week to find the house alarm was "had" been going off for several hours! Chris was in his room completely oblivious as usual. So I punched the code into the box! But the box was dead?  

 

out comes the test meter and yup, voltage there at the transformer so pops the main fuse onto the meter for a continuity test and bingo! Popped a new 1a fuse in and it fired up, shuts down the external box and all is well with the world! 

 

Roll on to last night and we suffer a power cut! Nothing unusual in that, except the alarm once again trips the instant the power goes off  out came the meter again and tests the charger feed plug, The battery is only 5 year old as I replaced it previously, but the output from the board is 0.04v ?  

 

Pop the charger circuit fuse out to test! Blown! I assume this also blew when the main fuse went, but not being glass you can't see the filament inside. So having already used my last 1a quick blow, I am trying to come up with a solution! Drill the fuse and solder in a new wire? 

 

so anyway I then Decide to remove the Battery and charge it manually only to find the bottom has blown out! So it appears that I had a spike either from the mains, or from the battery blowing! I have now had to place an order for new fuses, and will have to find a new battery too. 

 

Think I will rig up a makeshift 12v feed out of some 18650s for tonight so I can at least get some uninterrupted sleep ? 

 

On a a positive note, the house is almost never unoccupied anyway as chris doesn't leave the house. I think he may be agoraphobic! Suffers anxiety and feels like he is going to vomit when he steps outside the door? So the alarm is not too important.
