Amazing grace Posted December 4, 2003 Share Posted December 4, 2003 I am going bl++dy mad, I used the fag lighter to run polishere this afternoon, after I had finished went to put car in garage and she would not start alarm went off immediatly (is it the immobilizer )will not let me start car. locked car again waited then opened her up again got in tried to start her again light on dash come up then the alarm kicks in lots of noise and still no ignition. Then I thought it may be because I had wound the battery down with the polisher so I try to jump start her (Just spoken to Oxygen and he told me I should'nt have done this, I explained it was only done v.short time as I quickly realized this was'nt helping so I hope to God I hav'nt fried MY CAR) ASm really scared now still can't start car and may have fried computer in car, think I might just sit down and have a girlie cry Sob. If there is anyone who could offer any help I would be so GRATEFUL. Sheena. Many Thanx in anticipation. Link to comment Share on other sites More sharing options...
mawby Posted December 4, 2003 Share Posted December 4, 2003 Chances are you haven't fried anything. Mine did exactly the same thing about a month ago. I parked up outside my girlfriends house, came to start the car 3 hours later and there was just a thud, click and then the alarm sounded. (nothing left on I might add, still a bit of a mystery as to why it went flat) I had to resort to jumping it, but this took several attempts because of poor connections at one end or the other of the leads. I knew when there wasn't a good connection because the alarm would sound as soon as I tried to start it. I then found that if you fiddle with the leads when the alarm is sounding you'll soon find out when the connection is good because the alarm gets considerably louder! And you can also turn it off at this point, something I couldn't do when the alarm was sounding using it's backup battery. I think if your jump starting had no affect then this was because of a poor connection, so as soon as you tried to start the car it will drain all the power from the battery which makes both the alarm think it's being tampered with and engages the immobiliser, so the engine wont even turn over slowly. Best answer I can give you is to burn down to Halfords or similar and get a replacement battery. Bung it in and I bet it starts first time.

Willson Posted December 4, 2003 Share Posted December 4, 2003 I have never heard that it is a bad idea to jump start the supe Link to comment Share on other sites More sharing options...
Amazing grace Posted December 4, 2003 Author Share Posted December 4, 2003 Mawby thank you SO much for replying, I have been worried sick that not only did I have a car that would not start but the idea that I might have fried her brains out a well was more than I could think about not to mention the fact that my husband was likely to kill me along with my bank manager!!!! How much is a new battery? and is it very difficult to fit(alarm system etc. I really am a dive when it comes to anything mechanical, do you think the AA could help?) sorry so many questions, but completly stumped here?

Nick Posted December 4, 2003 Share Posted December 4, 2003 You shouldn't really jump start them but I wouldn't worry about it. Battery is 40-50quid and a doddle to fit. Carefully disconnect both the terminals and then undo the bracket, remove and refit. 5 minute job. Be prepared for the alarm to sound when you reconnect the battery.

mawby Posted December 4, 2003 Share Posted December 4, 2003 Most alarms have some way of disabling them so you can disconnect the battery. Then it shouldn't go off when you disconnect/reconnect the battery, mine didn't anyway. When you get a replacement make sure the terminals are the right size and the battery dimensions are as close the current one as possible. The one I got from Halfords is about 1cm shorter, but it still fits with a slight modification to the supporting bracket. If you're not too sure take the old battery with you and tell 'um you want one to replace it. Oh, another thing to watch out for is which way the terminals are, ie which one is positive and which is negative. Link to comment Share on other sites More sharing options...
oxygene Posted December 4, 2003 Share Posted December 4, 2003 Hi Guyz Sorry if I gave AG the wrong info, it was origianlly told to me by an AA engineer who came out to me when I was stranded with a knackered batery. He said that MKIV ECU's didnt like being jump started and not to try it as I might blow the thing up... Sorry again if I gave AG the wrong info, was just trying to help her out with a rather sticky situation. Link to comment Share on other sites More sharing options...
Nick_TC Posted December 5, 2003 Share Posted December 5, 2003 There are a couple of recent threads about jump starting. You have to be VERY careful jumping any car with an ECU or Air bags. Link to comment Share on other sites More sharing options...
Willson Posted December 5, 2003 Share Posted December 5, 2003 Can you give me any advice, in case I should need it. I have jump started my car about 5 times. Me being a dinlo, leaving my lights on No probs yet, but............ Link to comment Share on other sites More sharing options...
Nick_TC Posted December 5, 2003 Share Posted December 5, 2003 The best advice is go and buy a booster pack and throw your jump leads away. Bad connections with jump leads have been known to fry ecu's and set off air bags. If you have to use jump leads connect to the flat vehicle first, preferably with the negative lead onto an earth i.e engine bracket or chassis, then connect to the charging vehicle, connecting the positive lead first then the negative.

And make sure the donor vehicle is not running until all the connections have been made, then start the other car and ideally, let it idle for a couple of minutes first.

Doug Posted December 5, 2003 Share Posted December 5, 2003 I joined the "Oh bollocks dead battery" club this morning. I am now the proud owner of a kwik fit battery sized to fit a Nissan Micra. Mr Harwood, I believe you now have something else to fix you lucky lucky chap. Link to comment Share on other sites More sharing options...
Whitesupraboy2 Posted December 5, 2003 Share Posted December 5, 2003 i have left this club all of 5 mins ago, went to halfords and had the test and they said the battery had snuffed it, i said of course it has it has halfords stuck on it.

Wez Posted December 5, 2003 Share Posted December 5, 2003 Not sure if its similar but I had a problem on my car which bugged me for about a week, when I tried to start it would just click and all power gone, then try again and completly dead then alarm would sound. I popped my bonnet and found that if I moved the battery terminals about it would fix it. In the end I turned the bolts round on the terminal clamps and they bit into the posts much better and haven`t had a problem since. Link to comment Share on other sites More sharing options...
