jonno Posted March 7, 2009 Share Posted March 7, 2009 hi, i bought my disco 200 tdi about a month ago and have been pleased with it. 2 weeks ago the alternator light came on and gave me typical alternator problems so i replaced the alternator and everythings been ok untill thursday morn when it decided to not start,( the night before was bad weather and i was using wipers,heater,lights,radio etc).engine wouldnt turn only a clicking for a few seconds then nothing.also i had no central locking, alarm or electric windows though everything else works. so i bumped it down the hill and it drove fine till i turned it off. i put the battery on charge all night. next morn put the battery back on but it was exactly the same so i changed the battery and still it is the same i have to bump it when i want to use it. so i have changed the alternator,battery and the battery earth looks ok and isnt loose and ive checked the fuses also it has a single button alarm fob. any suggestions or comments would be apreciated. thanks,jonno.

gsmajd4x4 Posted March 8, 2009 Share Posted March 8, 2009 Oh dear, well it certainly sounds like the battery You mention that you've tried another battery - was this a new one or could it be that you inadvertently have 2 failed batteries. Once the vehicle is started and has run for a little while, will it turn off and immediately start again? You also changed the alternator prior to having 'this' problem. I wonder if that is a coincidence..... Is it worth double checking that there isn't some kind of short circuit around this area?? Just a few thoughts.....

Gozling2 Posted March 8, 2009 Share Posted March 8, 2009 Have you checked the starter motor?, it could well be either a siezed/very stiff starter bendix or a u/s solenoid, try connecting just the negative lead of jump leads (if you have) from battery negative to engine block to eliminate any earthing faults, hope this helps a wee bit.

jonno Posted March 8, 2009 Author Share Posted March 8, 2009 i charged the battery ovenight and tried it again this morn and all i am getting is a clicking noise.tried using jump leads to earth battery but still the same. how do you test the starter motor?

Just a few thoughts..... i have to bump it every time i want to start it even after an hours constant driving i am going to get a multi tester and check battery. if that tests ok then ill change starter motor but i cant see how a dodgy starter would effect elec windows an central locking.

Gozling2 Posted March 8, 2009 Share Posted March 8, 2009 i charged the battery ovenight and tried it again this morn and all i am getting is a clicking noise.tried using jump leads to earth battery but still the same. how do you test the starter motor? let the battery stand overnight and then check it, voltage should be 12.5 v or more ..if low battery suspect. With engine at 2-3000 rpm with everyting turned off check voltage at battery it should read 14.4-14.7v if below 14.4v faulty voltage regulator in the alternator. check all voltages going to starter solenoid if all is ok then easiest way to check the starter is to remove it and place it in a vice then attempt to turn the bendix on the starter it should rotate freely if not it might need lubrication and freeing off.

jonno Posted March 9, 2009 Author Share Posted March 9, 2009 let the battery stand overnight and then check it, voltage should be 12.5 v or more ..if low battery suspect. With engine at 2-3000 rpm with everyting turned off check voltage at battery it should read 14.4-14.7v if below 14.4v faulty voltage regulator in the alternator. i got hold of a tester today and these are the voltages old battery is showing 12.5v new battery 13.4v with engine running it is 14.5v so i guess new batt is ok and so is alternator and old battery not so good so next ill check starter motor snd see what voltage is reaching it also i still have no central locking or windows working with engine on or off could it be caused by a faulty startermotor are have i been unlucky and had several problems appear at once?

jonno Posted March 9, 2009 Author Share Posted March 9, 2009 just checked volts to starter motor the large wire is reading 12.7v the small wire 5.4v when the key is turned in the ignition i have also noticed that the little red led on the dash for the alarm is constantly on when trying to start it all i can hear is a clicking from the passanger side footwell all i can do now is remove the starter motor and see if has froze up inside unless any one has any ideas what else to check or try Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted March 9, 2009 Share Posted March 9, 2009 Is the clicking really loud, from the starter, or is it just a relay clicking in the passenger footwell? If the alarm LED is on then I suspect the alarm is still on, and it includes an immobiliser which is killing your starter circuit. Quote Link to comment Share on other sites More sharing options...
jonno Posted March 9, 2009 Author Share Posted March 9, 2009 thanks for the replyBowie69 the clicking is definately coming from the footwell inside the car and not from the startermotor hte disco is a 1994 with a single button fob after reading other posts i thought that single button fob meant no immobiliser but it makes sense that the alarm is armed as i have also lost cental locking and electric windows aswell if it is alarm related what are my best options?

TheRecklessEngineer Posted March 9, 2009 Share Posted March 9, 2009 How definitely? The clicking is a classic symptom of a flat battery. Normally, it is the solenoid shuttling back and forth trying to engage starter. Quote Link to comment Share on other sites More sharing options...
jonno Posted March 9, 2009 Author Share Posted March 9, 2009 had my head in engine bay while my mate was trying to start it and the starter is silent i took the trim off from the footwell side and theres a row of relays,the clicking is from there Quote Link to comment Share on other sites More sharing options...
jonno Posted March 9, 2009 Author Share Posted March 9, 2009 just searched the forum for alarm related probs and found an old post from someone having similar probs with an l reg disco but no one has posted a solution only that water getting into the alarm ecu under steering colum caused it which sounds right as my probs started after a heavy downpour Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted March 9, 2009 Share Posted March 9, 2009 Take a wire from the positive battery terminal and touch it on the small terminal on the starter -if it cranks your battery & starter are fine, and the fault is either your immobiliser, ignition switch or a relay between the two. I don't have a wiring diagram but I am sure there is someone on here that has Quote Link to comment Share on other sites More sharing options...
jonno Posted March 9, 2009 Author Share Posted March 9, 2009 had a good look through previous posts and i am sure it is an alarm fault i will try adding the live straight to the small terminal and see if that works ill post back when ive tried it Quote Link to comment Share on other sites More sharing options...
jonno Posted March 9, 2009 Author Share Posted March 9, 2009 just been and tried 12v to starter and it cranked over a treat so startermotor is ok and ruled out cheers for the the tip bowie69 that saved me removing starter motor tomorrow. so im looking at alarm ecu or relay Quote Link to comment Share on other sites More sharing options...
jonno Posted March 12, 2009 Author Share Posted March 12, 2009 thanks to all who replied to my posts it is now starting ok and everything is working as it should. it turned out to be a corroded solodered joint on the fusible link which ran to the alarm box. i re-attached the link and everything is now working. jonno.
