Title: Wierd Battery Draining Problem...
Post by: Loxam on August 07, 2006, 04:25:41 PM
Im still here and still sorting my FC :P

I have a wierd problem with my battery, and I can\'t work it out.  Everytime I leave the battery attached and the alarm on, after say 8 hours ish the alarm goes mad then when I try to start the car the battery is flat.

The connectors to the battery (terminals) are a bit shoddy tightening up and one of the hoops is actually broken (god knows how).

What I can\'t work out is whats draining it or common causes of a drain.  Is the alarm sucking the power, is it the connectors that are causing the problem or something else?

I have bought a brand new battery now and have it disconnected from the car when im not using it.

Any help on this would be appreciated - if it is the alarm im thinking of ditching it completely and getting a quick release steering wheel :Thumbs-up

The alarm is a cat1 clifford cobrathing

i had the same prob - it was the stock panic alarm draining the battery

have you a red switch on the side of the steering colomn ???

if so thats a panic button

has the orig mazda alarm been fully removed ??

im sure there is a way to check for bad earths aswell - something about a test lamp from the negative battery terminal to the body - if this lights the lamp you have a bad earth - or summat like that - i assume you can use a volt meter aswell - if that shows a voltage - then you have a drain on the battery somewhere

what happens if you pull the EGI and MAIN fuse - does it still drain ???

this is ALWAYS a good one to check - is the boot light off ??? i have heard many stories about this draining the battery !!

Don\'t some alarms go off if the battery is low?

So, could be a duff battery. Attach the new battery, and find out. Or, alternatively, get the old one checked out. It may be that it just can\'t hold any charge.

Ok update.

I think this alarm does go off if the battery is low.  I had the old battery checked out, and it was goosed but the guy seemed to think this was due to the alarm draining it (chavfords though ;)).

Checked the boot light, it was in the on position, I switched it to off now just to make sure.

There is a panic button installed - could this be the problem?

Im guessing seems this alarm was installed professionally at a garage (by original owner - Paul) that the previous system was fully removed - is there anyway to check though?

Not checked bad earths yet.

Not pulled fuses yet.

I have disabled the alarm for now, and checking it overnight to see if its drained in the morning.  If it is then I know its definately not the battery (its brand new) and something else.

you can check the fuses - i cant tell you which ones though as it would allow anyone to turn the stock alarm off

I have a similar problem on my FD - I might have fixed it now but i\'m not sure as I\'ve only left it for 4 days without starting it...

See if it makes a week then I\'ll know.

You\'re right tho when the battery dies the alarm has an internal one (at least mine does) once that drops below a certain voltage then the siren sounds.  ****ing my neigbours off no end if I\'m at work and it\'s the middle of the day :)

I\'ve made some custom earth straps from the engine to the body and double earthed the battery to the body.

My problems I thought were related to the connectors/fuses left over after the ABS was removed but not true...

I\'ll let you know what I find.

Have you tried a meter on amps with ign off to see what sort of current drain there may be? If you are pulling some still, whip the fusses out one at a time untill it goes? or the other way round and remove all and load up one at a time.
I\'ll pm you with the alarm details that I remember

Alarms have \'built in\' system for voltage drop...this is in case somebody gets their hand under the bonnet to cut the battery cables to disarm the battery !
If the alternator is functioning incorrectly you will have additional probs.....as the advice goes,look for a \'system\' which is drawing the current even when ignition is off:Typing

UPDATE: Checked it this morning and it started up fine, maybe it was just the battery had goosed *fingers crossed*

This is all with the alarm disabled.  Ill see how it gets on in the next few days.

Then ill re-enable the alarm and see what happens :D
