RINRIN 1 Posted November 27, 2008 Hi, Last night I went to the garage and get in my pug. I turned the keys and nothing happens. Then I remember that there was a problem with the alarm. So I bought a new battery. By the way I measured the resistance between the + and the - battey cables. The reslt was 9 Ohms between the cables. Is that normal or there is a bug in the system?

With the battery connected? With everything switched on but the batt disconnected? or do you mean 9 Volts measured on volts? Share this post Link to post Share on other sites
large 33 Posted November 27, 2008 That sounds a bit low to me, a reading of 9 oms will give you a drain of about 1.3 amps. Share this post Link to post Share on other sites
RINRIN 1 Posted November 27, 2008 With the battery connected? With everything switched on but the batt disconnected? or do you mean 9 Volts measured on volts? Battery disconneted, only cables, obviously all closed That sounds a bit low to me, a reading of 9 oms will give you a drain of about 1.3 amps. Low is OK then, this will last the battery life:) I turned the alarm off. so what do yoy think? Share this post Link to post Share on other sites
large 33 Posted November 27, 2008 NO! low is BAD If you have nothing turned on your resistance should be up in the meg ohms. As I said you are using 1.3 amps with the car turned off so after a day or so you will have a flat battery. Share this post Link to post Share on other sites
RINRIN 1 Posted November 27, 2008 S**t When I turn the alarm on the resistance goes to Mohms, and ı thought it is to high. Then I turn the alrm of and reduces to 10 ohms I need to disconnet he battery then Share this post Link to post Share on other sites
large 33 Posted November 27, 2008 Or you could fit a battery cut off switch. Share this post Link to post Share on other sites
welshpug 1,678 Posted November 27, 2008 (edited) just a dis-carnect will suffice (or trace the fault) Edited November 27, 2008 by welshpug Share this post Link to post Share on other sites
RINRIN 1 Posted November 27, 2008 OK Thanks now I go and disconnect the battery. Later I will trace it Share this post Link to post Share on other sites
large 33 Posted November 27, 2008 Trace the fault would be the thing to do. Just thought I would suggest the cut off switch as it is a quick fix and saves the agrow of going under the bonnet every time you want to use the car. Share this post Link to post Share on other sites
ablister 31 Posted November 27, 2008 what resistance are in your multimeter leads? Share this post Link to post Share on other sites
RINRIN 1 Posted November 27, 2008 Ok I come back, I am sure there is problem 10 ohm between battery cables when alarm off M ohms when alarm is on. Share this post Link to post Share on other sites
large 33 Posted November 27, 2008 How can you test resistance with the alarm on? You can't test the circuit with the battery connected. Share this post Link to post Share on other sites
SeanO'Connor 0 Posted November 28, 2008 Are you sure your alarm isn't bust? Could be that causing your drain, may battery was always running flat, so I removed the alarm no problems at all now. Share this post Link to post Share on other sites
RINRIN 1 Posted November 28, 2008 How can you test resistance with the alarm on? You can't test the circuit with the battery connected. There is a key on the alarm to make the alarm on and off, No battery connection. Are you sure your alarm isn't bust? Could be that causing your drain, may battery was always running flat, so I removed the alarm no problems at all now. I am afraid of that. Today I found that the alarm connection for the bonnet was gone and I fixed it now the alarm works fine, but I need your comments on this. When the battery connected the resistance between + and - goes to Mega ohms, when I emove the battery the resistance drops to 30 ohms now. What do you say now, the resistance goes to Mohms with battery connected is this ok? and without battery it sucks I don no please comment. Share this post Link to post Share on other sites
large 33 Posted November 28, 2008 To be honest i dont know what you are on about but if you have your resistance up to 30 ohms that is only pulling 400mA which may be normal for your alarm. Share this post Link to post Share on other sites
RINRIN 1 Posted November 29, 2008 At last I found the boot light was open always and the alarm was failing to secure the bonnet, after resolving that I also renewed the earth points, at the end I had 12mA passing in the system, This results 1Mohms, Share this post Link to post Share on other sites
