gadgetnut74 Posted December 14, 2008 Share Posted December 14, 2008 Hi Guys, Another day another refusal to start .. Last time I found they hadn't topped up the battery fluid seemingly in either service as the level was so low.. This time there's no excuse so any suggestions on battery replacement?? Looks to be a bit of a job to remove the bugger!! While I'm on, anyone else had issues with pock marked windscreen? I also have a nasty scratch on the INSIDE of the windscreen I just noticed.. how the hell did THAT happen!!?? Quote Link to comment Share on other sites More sharing options...

dcash5 Posted December 14, 2008 Share Posted December 14, 2008 First thing to identify .... If its a JDM they have a very small battery which are prone to drain, especially if its a few years old and getting punished in the cold weather. Removing the battery is very easy.... few trim panels held in with plastic clips. Once off, two battery clamps on each terminal and then two bolts on the battery clamp. Best thing to do it identify if the battery is at fault, if so replace the battery. (Places like halfords can perform a battery check Free of Charge) If the battery is good... you need to source the drain - easier said than done Quote Link to comment Share on other sites More sharing options...
gadgetnut74 Posted December 19, 2008 Author Share Posted December 19, 2008 Hi All, Well mobile mechanic and AA agreed the battery wasn't accepting a charge.. took it to Nissan, and their automated test said it was fine, despite not starting 3 times in a fortnight (having been charged in meantime..) There is no trace of a drain on the battery at rest. (Car is an 06 Uk roadster btw) I Paid for the battery as can't afford to lose the job over this (£130 fitted!) but notice its still charging heavily after starting (ie Volts hit 15.7v, then slowly make way down to 14v over 20-25 mins.. Just wondered how your voltmetres are looking this winter, the above sound normal enough? Just don't want to leave the car for 3 days again and it find it doesn't bloody start!

Looks like you may be overcharging mate. Overcharging causes excess heat at the battery resulting in battery failure. Get your charging rate checked to be on the safe side. Nissan should have done this at the same time as battery testing and subsequent battery replacement. Alex. Quote Link to comment Share on other sites More sharing options...
Chris`I Posted December 19, 2008 Share Posted December 19, 2008 Being a bit naieve in this area, does the car change the rate of charge on the battery? I've noticed recently that my voltage readout on the pod seems to be higher than normal. Not taken any specific readings (can do off the CarPC PSU if needs be), but assumed it was down to the weather. Could it be the battery on the way out? I have a mate who works at Halfrauds so could get him to do a batt check if you think it could. Quote Link to comment Share on other sites More sharing options...
gadgetnut74 Posted December 19, 2008 Author Share Posted December 19, 2008 When Jump started from dead it was charging at 80A, When driving voltage normally sits at 14V, 15.X for a while (15-20 mins) after starting.. The Battery was replaced (allegedly) but voltages have remained same.. Quote Link to comment Share on other sites More sharing options...
Darren-B Posted December 19, 2008 Share Posted December 19, 2008 im no expert, but if your running, blowers, rear screen, lights and arse warmers it will put alot of strain on the batt and alternator, making it work harder and may produce a little higher voltage 2produce the sufficent amperage 2run these plus charge the batt.

gadgetnut74 Posted December 20, 2008 Author Share Posted December 20, 2008 Car batteries are less efficient when cold, but even avoiding using heated windscreen, radio, and heated seats didn't help! Quote Link to comment Share on other sites More sharing options...
Martin W Posted December 21, 2008 Share Posted December 21, 2008 Car batteries are less efficient when cold, but even avoiding using heated windscreen, radio, and heated seats didn't help! you aren't accidentally leaving the seat warmers on are u = the manuals warn this will drain the battery. they work - heating away - even when keys are safe at home.

Ekona Posted December 21, 2008 Share Posted December 21, 2008 Really? I leave mine on all the time, but figured as how there's no light on the switch and the seat is stone cold when I get in the next day, it's definitely not on. Maybe it's different for earlier cars?

Maybe post54 cars are diff (for the better)! My warmer switches have lights too I had a 2 month spell with 6 or 7 AA callouts, when I thought I was looking I thought at a 4 figure auto electrician bill for some serious diagnostic work. Popped along as a last measure to change the battery, and as I carefully put the old one on the passenger seat, and as i did thought 'hangon.. why is that seat warm!!!!

gadgetnut74 Posted December 22, 2008 Author Share Posted December 22, 2008 I have the lights on my heated seats too, and they're off.. I've been keeping everything but the lights off! What do you guys see as the voltage a little while after starting? 15v+? I'm still seeing 15.1 for a while, the drops down to 14 on the nose after 15 mins driving..

This is far to high if you have a new fully charged battery. As I advised previously, Get Your Charging Rate Checked to avoid further unnecessory expence.

Stew Posted December 23, 2008 Share Posted December 23, 2008 I think an alternator works at 14.4V so I would have thought around that. Quote Link to comment Share on other sites More sharing options...

Sorry guys, was reading this thread wrong. 13.6 - 14.4 is the normal charging rate that should be showing. Quote Link to comment Share on other sites More sharing options...
gadgetnut74 Posted February 9, 2009 Author Share Posted February 9, 2009 Well.. another day another dead battery.. the new one of course (replaced in dec after 3 failures despite Nissan's computer saying battery was fine..) this time deader than a dead thing.. so back at dealer.. did find it had a 0.5A draw when all locked up so something not right.. waited 15 mins for ecu etc to shut down but no change.. anyone know how long before car should be down to normal (typically 0.03-5A) load? Given I had to pay £134 for a new battery in dec, should I be expecting a warranty claim this time? Quote Link to comment Share on other sites More sharing options...
M13KYF Posted February 9, 2009 Share Posted February 9, 2009 you haven't got a interior light staying on by any chance. Check the boot one as well Quote Link to comment Share on other sites More sharing options...
gadgetnut74 Posted February 9, 2009 Author Share Posted February 9, 2009 No all checked.. and its 0.5A! I did wonder if it was an old tracking unit that hasn't been uninstalled.. covert fit though as i've looked in usual places (What I do for a living) Quote Link to comment Share on other sites More sharing options...
gadgetnut74 Posted February 11, 2009 Author Share Posted February 11, 2009 Ok problem found but dealer being a pain.. as i'd found a 0.5-0.8A draw on battery, dealer worked on this for 2 days, and eventually found a cut wire behind dash which had been repaired by .. twisting them together .. it was shorting and draining.. probably remnants of an old phone kit from previous owner.. The problem I have is I bought this (06) car in October, first took it to dealer with the issue in early december and though battery passed test, I ended up with a new one as nothing else could be found as cause, and I was £140 lighter (warranty claim not valid as battery within nissan norms and i needed the car back.) Now Wilsons epsom want £185 in labour charges for finding the fault (which they sold me) .. Service and Sales can't agree on who should pay and after 3 days are asking i go in to mediate!?? (Sales say as out of the 3 months its my cost) Is it me or are they out of their minds? Recommendations guys? Quote Link to comment Share on other sites More sharing options...
Toon Chris Posted February 11, 2009 Share Posted February 11, 2009 Yes, they are out of their minds! You first reported the problem in December, within the 3 months they think is the limit. That it took so long to find the problem shouldn't be relevant to you as the problem was there from the start and did not develop over time. Sales pay and then argue the toss with servicing without involving you. I would recommend you write straight to the manager of the branch and say you are not interested in watching them air their dirty washing, not to charge you and to sort it out within themselves.

Ask the manager there for the warranty departments number & phone them i had a similar issue with my window motor, I had reported it before my warranty had expired but by the time i got the car in for them to look at & they diagnosed the fault it was out of warranty. Sales wanted nothing to do with it & neither did the service dept. Thats why I went direct to the warranty department & they agreed to pay for it Quote Link to comment Share on other sites More sharing options...
