captain Posted March 14, 2010 Share Posted March 14, 2010 Flat battery this morning. It was turning over the starter motor but just clicking. Went and got the charger which also does jump starts. (It's got a "fast/start" function) Left the battery in the car and then connected the charger to THE WRONG TERMINALS!!! I noticed this before I restarted and quickly turned off the charger. I re-connected the charger correctly but when I turned the ignition the car is completely dead. No lights on the dash and no turnover of the starter motor. Have I done something expensive?

gunmetalzgt Posted March 14, 2010 Share Posted March 14, 2010 Firstly, Check fuses. Then check the voltage on the battery. If you manage to get it to start, check the voltage across the battery again to make sure you didn't fry the alternator. Quote Link to comment Share on other sites More sharing options...
captain Posted March 14, 2010 Author Share Posted March 14, 2010 Ta. How do I check the voltage across the battery? Do you mean via the dial on the dash? And if I've fried the alternator? Any idea of cost? Last. Do you think I've done something to the immobiliser? G/F reckons that's what I've done. Quote Link to comment Share on other sites More sharing options...
nurrish Posted March 14, 2010 Share Posted March 14, 2010 I had something similar a couple of days ago..... on the battery check the fuses directly on the positive terminal.....most likely one of these has fried.....just reconnect the join with something Quote Link to comment Share on other sites More sharing options...
yokomo Posted March 14, 2010 Share Posted March 14, 2010 posibly a totaly dead battery? Quote Link to comment Share on other sites More sharing options...
Husky Posted March 14, 2010 Share Posted March 14, 2010 all automotive manufacturers "should" design to protect against user error when connecting chargers etc. but then ive seen nissans design be a bit sloppy before. also the charger should have some protection aswell i would hope. i wouldnt think you've done anything to damage the car but the battery may be damaged.

gunmetalzgt Posted March 14, 2010 Share Posted March 14, 2010 You may need a volt meter to check the voltages, but as husky said check all fuses. in the engine bay and also in the car. you shouldn't have a major problem in my opinion. Don't worry it should be fine Quote Link to comment Share on other sites More sharing options...
captain Posted March 14, 2010 Author Share Posted March 14, 2010 I had something similar a couple of days ago..... on the battery check the fuses directly on the positive terminal.....most likely one of these has fried.....just reconnect the join with something There appear to be 5 fuses attached to the + terminal (4 underneath and 1 just on the top right) all appear fine. I'll check the ones in the engine bay a little later as have to go out. Hate to say this, but where are the fuses inside the car mentioned above?

Hate to say this, but where are the fuses inside the car mentioned above? something HAS to be a fuse! do not under any circumstances use anything but the correct rated fuse. disregarding this will potentially leave you with a burned out heap in your drive and no insurance pay out.

Ekona Posted March 14, 2010 Share Posted March 14, 2010 The alternative is that you've fried the ECUs and melted the wiring. Happens very often when people connect the terminals the wrong way round. You may have got lucky and it's just a fuse, but prepare yourself for the worst just in case. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted March 14, 2010 Share Posted March 14, 2010 More than likely the top main fuse link at the + terminal. I hope not as they are not a two penny fuse. Alex. Quote Link to comment Share on other sites More sharing options...

Maccaman Posted March 14, 2010 Share Posted March 14, 2010 I connected the wrong terminals on my mothers Mazda and fried a big fuse. Didn't cost to much to replace though. Quote Link to comment Share on other sites More sharing options...
Andy Posted March 14, 2010 Share Posted March 14, 2010 Similar thing happened to mine last week. Was the fuse below on mine. Nissan will want £56+vat for a new assembly Quote Link to comment Share on other sites More sharing options...

Remind me to give you a Chinese burn, a running deadleg and turbo-wedgie next time we meet. Had the battery of super charge for 5-6 hours. Popped it back in and everything OK. Don't know why it was dead earlier. Perhaps the car went in to "I'm being stolen" mode as it was very similar to the immobilser kicking in. Have bought a new battery from our f®einds at Halfords (£89 ) and will take it back tomorrow if the car starts in the morning. Thanks to all for your suggestions and concern.

How's that study looking? Don't want to get blamed for distracting you. Rota's arrive tomorrow and rubber later in week and then there's Nurrish's mega-brake set up going on and then the aluminium grille and the Scorpion so I think you'll be round quite a bit over next week or so having a look as each bit goes on......................

GT4 Zed Posted March 14, 2010 Share Posted March 14, 2010 Good to know that you have fixed it and that you were lucky not to blow the fuses or worse. careful next time Quote Link to comment Share on other sites More sharing options...
captain Posted March 14, 2010 Author Share Posted March 14, 2010 Should I keep the battery on fast charge overnight? It's got 5 LEDs on the front and the green one at number 5 is bright green next to the word MAX whilst it's charging (now). When I turn off the charger but leave the battery connected to it, the LED light drops back to number 3 and goes amber. This suggests the battery is half-charged but the instructions are half English and half space-martian having been badly translated. Quote Link to comment Share on other sites More sharing options...

captain Posted March 15, 2010 Author Share Posted March 15, 2010 AAAAAARRRRGGHGHHHHHHHHHHHHH!! Gone again so battery must be dead. However, need a JDM-style battery with smaller terminals as Nissan say they can't get UK ends for the + and - leads for 3-6 weeks. Where can I source a battery with narrow terminals with a proper CCA (450 to 510 range) in next 24 hours?? Lots of local suppliers and Halfords have the 330 CCA but I'll only get that as a last resort. Thanks. Quote Link to comment Share on other sites More sharing options...
