Hey guys

I am planning to go overseas for 3 months. What if I just leave my car in the garage for 3 months will the bettary die when I back? However I am thinking if I disconnected the bettary it will clean the memory of the car, not sure it is harmful or not. Any ideas? :D:)

Hey guys

I am planning to go overseas for 3 months. What if I just leave my car in the garage for 3 months will the bettary die when I back? However I am thinking if I disconnected the bettary it will clean the memory of the car, not sure it is harmful or not. Any ideas? :D:)

I would think if you have an alarm that would be the biggest problem in disconnecting the battery. It is recommended if U go away for more than 4 weeks that U disconnect the battery, however, that doesn't stop it from draining as all batteries discharge over time. First, make sure it's filled up fully with distilled water and is fully charged and then store it in a cool place. Then, the best way to maintain the battery would be to buy a battery charger with a trickle charge facility. I used to work at Jaycar Electronics and they sold some really good value for $$$ car battery chargers. However, I'm sure any other product of similar specifications would do the job, not just Jaycar's (i.e. I'm not promoting Jaycar merely because I worked there).

Just an example of one:

That plugs directly into your mains outlet so it shouldn't be a problem.

It won't "clear" your memory, just reset your clock and erase your radio presets so U should be fine

yeah something like that jaycar maintenance charger would be perfect. otherwise just disconnect the battery. if you take it out of the car do not put it on a concrete surface it will discharge quickly and be ruined. if you must put it on the floor at least put a plank of wood or something between it and the concrete.

it won't hurt your car not having a battery for 3 months.

Hahaha, thats the funniest thing I've heard for awhile, you obviously skipped science at school. :P

try it. the cold surface of the concrete will help speed up your batteries discharge. it's not a matter of science it's a matter of practical experience. but if you know better, go put your battery on the concrete floor of your garage for a week or two and tell me how that works out for you.

The cool surface acts a heat sink for the battery which after a period determined by the ambient temperature will slow down the electrochemical reactions in the battery making them appear flat in the short term. Given a bit of time to warm up, they will recover.

And I do have a battery on the concrete in my garage as we speak, always done it, never an issue.

Are you religious?

The materials that modern battery cases are made of are less condusive to leakage (and better sealed) and from a "modern" battery's perspective, I doubt there will be any leakage or acceleration of discharge by leaving it on a concrete floor. The biggest problem is dirt build up whilst on the floor. When dirt builds up across the terminals, it can form an acidic layer which can carbonise the dirt into an electrical conductor of sorts thereby creating a short circuit of sorts across the terminals which subsequently drains the power a lot faster. From working at Jaycar and dealing with a lot of auto-electricians and mechanics, I've also heard (though I've never seen it proved) that thermal gradients can also redude the life of a battery - i.e. if the surface the battery is sitting on is a lot warmer than the ambient temperature around it.

Appreciate for all advices. :( Think I am going to buy a battery charger. By the way, any other issues need to be concerned? such as engine,transmission,oil..etc. Thanks :(:(

Nah mate, they're all sealed up, you'll be fine. Maybe factor in an oil change when you get back.

Enjoy your trip, don't stress about the car :blink: .

    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
    • So I found this: https://www.efihardware.com/temperature-sensor-voltage-calculator I didn't know what the pullup resistor is. So I thought if I used my table of known values I could estimate it by putting a value into the pullup resistor, and this should line up with the voltages I had measured. Eventually I got this table out of it by using 210ohms as the pullup resistor. 180C 0.232V - Predicted 175C 0.254V - Predicted 170C 0.278V - Predicted 165C 0.305V - Predicted 160C 0.336V - Predicted 155C 0.369V - Predicted 150C 0.407V - Predicted 145C 0.448V - Predicted 140C 0.494V - Predicted 135C 0.545V - Predicted 130C 0.603V - Predicted 125C 0.668V - Predicted 120C 0.740V - Predicted 115C 0.817V - Predicted 110C 0.914V - Predicted 105C 1.023V - Predicted 100C 1.15V 90C 1.42V - Predicted 85C 1.59V 80C 1.74V 75C 1.94V 70C 2.10V 65C 2.33V 60C 2.56V 58C 2.68V 57C 2.70V 56C 2.74V 55C 2.78V 54C 2.80V 50C 2.98V 49C 3.06V 47C 3.18V 45C 3.23V 43C 3.36V 40C 3.51V 37C 3.67V 35C 3.75V 30C 4.00V As before, the formula in HPTuners is here: https://www.hptuners.com/documentation/files/VCM-Scanner/Content/vcm_scanner/defining_a_transform.htm?Highlight=defining a transform Specifically: In my case I used 50C and 150C, given the sensor is supposedly for that. Input 1 = 2.98V Output 1 = 50C Input 2 = 0.407V Output 2 = 150C (0.407-2.98) / (150-50) -2.573/100 = -0.02573 2.98/-0.02573 + 47.045 = 50 So the corresponding formula should be: (Input / -0.02573) + 47.045 = Output.   If someone can confirm my math it'd be great. Supposedly you can pick any two pairs of the data to make this formula.
    • Well this shows me the fuel pump relay is inside the base of the drivers A Pillar, and goes into the main power wire, and it connects to the ignition. The alarm is.... in the base of the drivers A Pillar. The issue is that I'm not getting 12v to the pump at ignition which tells me that relay isn't being triggered. AVS told me the immobiliser should be open until the ignition is active. So once ignition is active, the immobiliser relay should be telling that fuel pump relay to close which completes the circuit. But I'm not getting voltage at the relay in the rear triggered by the ECU, which leaves me back at the same assumption that that relay was never connected into the immobiliser. This is what I'm trying to verify, that my assumption is the most likely scenario and I'll go back to the alarm tech yet again that he needs to fix his work.      Here is the alarms wiring diagram, so my assumption is IM3A, IM3B, or both, aren't connected or improper. But this is all sealed up, with black wiring, and loomed
