Went to start the car today, ignition lights on, turned the key and nothing, all the lights went out, tried to restart, but the lights diddnt light up and had no power at all. I came back to it a few hours later, opened the door and the alarm went off, I couldnt turn it off so I opened the bonnet and touched the negative wire going to the battery very slightly and the alarm stopped and the car started straight away, the negative has been tightened as tight as it will go, but it seems that the terminal on the battery is too small causing a bad connection, ever since this has happened, im getting a high pitched buzzing even when the ignition is off, I cant pinpoint where it is comming from but it seems to be near the drivers side wing inside the car, should I disconect the battery completely and leave for a while, could this be the cause of the rough idling now and again?

i dont know about the buzzing but yes it can be the cause of the rough idle, i replaced mine a few months back after i was having all sorts of trouble and it cleared up my wobbly idle, and fixed my intermitant central locking

Where is your alarm sounder located? If it is near to where the buzzing is coming from, it could be that, I had a similar problem, although mine was from water damage... Get your self some thin bendable metal, and make a U-shape, that'll go straight onto the battery terminal, and effectively make it bigger, thus, proper connection... HTH mate...

No its not the alarm sounder, I will disconect the battery later and see if that stops it, thanks for the advice, I will certainly do what u suggested to get a tight fit.

 

Thanks

I think when you have bad grounding you will get unwanted electronic noise. try buying a grounding kit from that bloke on the http://www.300zx-club.com forum. i bet all your old grounding cables are greened up and rubbish this doesnt help with running much either.

Cheers mate, might just get myself that kit.

I their any procedure I need to follow when disconecting the battery, or is it a simple case of disconecting it and refitting?

How hard is it to fit the new grounding kit?

Its easy to fit mate. But you might just have a bad battery? That noise might be a stuck relay or something.

Just wraped a piece of wire around battery terminal and tightened securly, all is now ok, Thanks guys.

Would be worth getting a new connector and that grounding kit for peace of mind.
