The instructions say engine should NOT be running, but do not specify if key should be turned to "accessory". Will this make the battery go dead?

When engine is running, the alternator in your car charges the car battery, so the voltage in your car circuit is more than standard 12V (it will be somewhere between 13-14.4V). The compressor is designed to run from 12V and this is the voltage when the engine is stopped. Keep the ignition key in the position which powers all accessories but do not start the engine.

Oh, whoops. I used mine while the engine was running with no problems. My 12-volt ports aren't powered unless my car is at least in accessory mode.If you're really afraid of your battery dying, you're probably ok using it with your car on. Just wait until your car is started before plugging it in (to prevent a surge) and make sure your parking brake is engaged.

I am not a mechanic -- but -- since the max time you are supposed to use the compressor is 10 minutes with a 25 minute cool down in between uses - I don't think you will run down your battery

It did not drain my battery when in accessory mode, but I usually start the car right after using the inflator, just in case it took some of the juice out of the battery. If you have more than one tire to inflate, you could also start the car after you finish with each tire. It will probably depend on how old your battery is and how much computerized equipment you have on your car. Sorry I couldn't be more specific

I guess that would all depend on how long you have it running for, most people still charge their phones with the car off

The battery provides typically 10-12amps, when the battery is running you are provided 14.8amps. Likely, it doesn't have a fuse, or isn't built with the best quality and would draw too many amps thus destroying it

The tire inflator gets power from the cigarette lighter plug, so as long as the key is turned to a place where the cigarette lighter plug is on, you should be ok.
855896
Absolutely not, it only takes a few minutes to pump up the tires. Your battery would have to be in very sorry shape to run out using this device.

No. You will need to find a aux wire that is switched on and off by the key. Or you could install a relay wired to a switched power source and wire it directly to the battery or use a switch if you wire it directly to the battery, be sure to use a fuse for these last two options.

I agree with fireatwill's reply. Mine sits for weeks and works OK. I "top off the charge" usually when the green test light and the adjacent red light goes out. Be sure the connections are very securely made to the battery. You likely will not have enough power to crank a completely dead battery on a large high compression engine.

Turn off ignition make sure there is no load or disconnect Neg- Terminal, then Just connect to the battery and press the test button. I did not like this tester and returned it. Midtronics is the best in category

The accessory power cable needs to be wired to accessory power from the ignition switch. If you want the unit on without the switch on you have to wire the accessory wire directly to a hot wire, like the POS. on the battery. I believe the accessory wire is yellow but check your manual to be sure.

It should because no activity means the O2 is basically dead and not reading or responding to the ECU anymore ie, no activity. Its like just unplugging your O2 then letting your car run, the same DTC would come up.

Plug something in while the car is running. Look for the light on whatever it is that you've plugged in that tells you it is being charged. Turn off the car and remove key. Is the light still on?

And one outher thing. Just as the previous person mentioned. Wire it off of an ignition source of power so it also Gose off with the key. As to not drain the power. That's how I wired mine and it works well.

This thing will eat a battery up. The instructions tell you not to use it without the car running .

Unfortunately it does not. Unless you have a push button start it will not remain on. Have you tried getting a copy of the original key? Or is the ignition not turning properly?

If you do not have a working key:1. Insert a new cut key in ignition and turn key to the ON position for 10 minutes and 30 seconds.2. Within 45 seconds turn the key to OFF and then back to the ON position for 10 minutes and 30 seconds. 3. Within 45 seconds turn the key to OFF and then back to the ON position for 10 minutes and 30 seconds. 4. Turn key OFF then back ON. The key is now programmed. Start vehicle to test key.

I believe it wok fine when it is an OBDII. The biggest drawback to it is that when you turn off the key for about 3 minutes, the mpg resets and starts over. Seem to work well other than that.

It will probably keep running. The car does not shut off if the key is not there.

No, your vehicle needs to be running, or your ignition key turned to the AUX position.

If you wired it in directly to the battery and the lite is on when the key is off it in time will drain the battery it is a very small slow draw. With the key on and the vehical running it is no problem. I wired mine threw a wire that was only hot when the key is on, this shuts all the lites off when you turn the vehical off. Was used on 2014 RZR 900.

Insert your key into ignition turn the key to on and off without turning the engine on for eight times quickly in 15 seconds , than hit any button on the Fob or fobs to program. Once you do all those steps take the key out of the ignition and try the key fobs to see that they work. Also if you purchase this item , don't worry step by step instructions will come with your purchase. I did it, and it was very easy. Good luck.

agree with what everyone else has saidYou can disconnect the battery for 30 min this should clear the check engine light. If you need yo go threw emissions then you will have to make sure you go threw the drive cycles or you will fail for computer cycles not set. You can Google fastest way to do the drive cycle.
