Can anyone help?

Ive a problem with my battery holding charge. Its a reasonably new battery and an expensive one, its about a year old and up until a couple of months ago. i could leave my portable fridge going all day without a problem running off the main battery supply but now i cant even leave it for 2 hours without it having trouble starting.

If i dont have the fridge in the car i have no trouble starting it day to day unless i leave it unstarted for 5 or 6 days +. The fridge isnt a real big one its only one of those ones that can heat and cool so it doesnt drain that much power.

Could my battery be stuffed already? or clould it be my alternator not providing enough charge but you wouldnt think so because it starts from day to day without any problem. Could it be anything else?

Any help would be good?

Just got a battery check done and its all good. This has got me baffled!!!!

Probably voltage regulator! they tend to charge intermitently when on the way out. I would personally run a dual battery system if you are running a fridge then your primary battery would remain with enough charge to always start the stag thats what I run in my hilux its good piece of mind, but dont know where you would put second battery boot/etc. I use the red arc microprocesser to control my battery's it works well and not to expensive.You could also just use one of those jump start/powerpacks to run fridge! :domokun:

Second all this, could also be the alternator bushes; I've had similar symptoms/problems before. I don't know if the bushes on the nissan alternators are like the standard bosch ones that just swap out with a phillips-head screwdriver, but it's a pretty cheap (~$20-ish?) fix if they are.

For a second battery, you might be able to get up to an 18 amp say gel cel to fit under the spare tyre cover in the boot. Especially if it's rated to work on its side.

Sound's like what I hear all day - everyday! (I work in roadside assist!)

Closed Circuit + time = dead bty!!!

Dual battery setup or Good roadside assist plan!

I only had my ipod on for a few minutes + the kids in the back with the dvd's = whinge whinge whinge (Not even monday YET!)

Presumably you have checked that there is no load/drain on the battery when your car is "off"? Obviously any alarm/central locking circuitry etc will still be drawing current but it should only be minimal.

I had an issue where my fog lights were left on (my old stagea - s2) - which flattened the battery very quickly. Before that I had no idea they even worked or how to turn them on - but they must've been flicked on accidentally the night before.

I'm assuming you've checked all the obvious stuff like this but thought I'd mention it anyway...

Recommend removing the positive terminal from the battery and connecting it via an ammeter/multimeter (initially set to the 10 amp range) when the key is out and everything is off to check the current draw. If it's anything more than perhaps 100 milliamps, you're going to have flat battery problems sooner or later. Even then it should probably be less than 30 milliamps, not sure.

the quickest way to check your alternator and starter motor is to get a multimeter set to volts and put accros battery mesure the volts then get someone to statr the car while you watch the multimeter.

It should not drop below about 10.5 volts if none of the acc are on now with the car running the alternator should be putting out around 13.5v to 14.2v.

if the volts drop below 10.5 when starting you could have a problem with the starter motor polling out wich means it is earthing its self so therefore all of your power will just be going into the earth rather than into turning the starter.

As for the battery put a charger on it ( about 10 amps) and see if you can get rid of some of the sulfation off the plates , wich is what happens when a battery runs flat.

I'm running a small SLA (Sealed lead acid ) battery wich has around the 600 cca but it also can be used as a deep cycle battery i.e run accessories.

I use it to run lights off the plug in the back for when i do call out's ( i work for a battery shop)

If you have any more problems just ask.

      I had never actually looked into it, but aren't onboard compressors a thing in trucks?

      Anyone have this problem with their temperature gauge?

      By sunsetR33 · Posted

      Read the ECU for fault codes or have someone else do it. A faulty coolant temperature sender is usually listed in ECUs. If the sensor itself is not busted it can also be a bad ground connection. Or in a really unlucky case, damaged wiring.

      Anyone know this frontpipe?

      By sunsetR33 · Posted

      Can't be a Futjitsubo as those are made with a flex piece and Reimax is smaller in pipe diameter. If anything it is closest to a Mines pipe, but evidently it is not an actual Mines pipe.   Classic word humor

      By sunsetR33 · Posted

      Alright I will try to not forget.   As GTSboy replied to you already, problem is mainly the mismatch between the actual exhaust part and the denomination in the papers. That basically just looks like tampering to a cop, if they were to check your car and notice. If it had been done right they would have clarified it to be a custom pipe and just given it a certain part number that you have to engrave or weld onto the pipe. I will definitely inquire on what to do. Changing the pipe wouldn't be my favorite solution as it costs a bunch of money and the cat was fitted with the front pipe and exhaust under the car, and if the front pipe flange does not sit in the OEM location the cat will need to be refit for any other pipe to work. It also usually doesn't need a brand name or something like that, but more something like a part number. Usually for exhaust parts, on silencers and cat units specifically, there is a badge that reads the certificate number that belongs to these exhaust parts under EU regulation. You get these numbers after you put a part or group of parts through the tedious testing according to EU vehicle legislation and they pass. You can find these "part numbers" on various parts throughout a EU vehicle. On windows, headlights, engine parts, seat belts and so on. All these parts have gone through standardized testing and acquired a so called ECE or EG Certificate that makes them legal to use by themselves in all countries that adhere to these standards. You can also not alter these parts in any way, if you do they become illegal. An example for stampings on an exterior lighting part, the people who need to know can find the documentation for this unit in a database. I do not know what all the standards and so on mean.
