check the battery voltage with a digital meter, clean the cables and terminals replace any loose ones. check grounds
car off should be minimum or 12.5 anything less its probably a bad or low charged battery, with the car running with ac on and lights on high beams
should be 13.5-15v
anything less the alternator should be checked and or replaced. 13.5 is on the low side of the scale keep that in mind.
as far as the accessories acting up, a low battery or bad alternator will cause all sorts of things to flicker and act up so start with the above first
and good luck
if after all thats completed and your still over time having a dead battery you have a parasitic drain, every car has a small one normally but a big one can be big trouble,
disconnect the battery get yourself a test light. clamp one end of the test light to the positve cable (unhooked from battery) and touch the end of the test light to the + on the battery. if it lights up bright you have a parasitic drain. (something staying on,) unplug fueses until the light turns off and that fuse that was pulled right before the light went off is the circuit that's bad and needs to be checked. could be as simple as a light staying on or a aftermarket radio, but it can get as indepth as full electrical diagnostics
I think I can help here:
Make sure your headset and phone are charged before doing anything else. The blue light on your headset will come on when it is charging, and will shut off when fully charged.
To put your headset in pairing mode, make sure it is completely off first (no blinking blue light). Then hold down the Call button for 6-10 seconds until the blue light stays on. (It will likely flash once and shut off, but keep holding until it is all the way on and stays there!)
From there, go into the settings on your Droid 2 and access the bluetooth connections. Do a new scan for your headset if you don't see it listed, pair, and connect!
when you battery goes dead, the security system locks the car. When you charge the bathery, use the key to lock the door and hold until the alarm activates. open your door and you can now start your [email protected]
i opened it,the upper part does not detach completely but slides,the blue light turned off finally but then on pressing the button nothing happened.Now i'm charging the battery and the blue light is on as usual so i hope it's just out of energy and it will work again when recharge will be finished:)
Try the following:
1) Make sure the HS820 is fully charged up.
2) Remove the battery and SIM card from your phone for about 1 minute and put them back in.
3) As soon as your phone is booted up, access the "find devices" function for adding your HS820.
4) Hold the HS820 button down until the blue light is solid.
5) Then do whatever your phone requres to "search for devices."
6) Here's the key: as the phone is searching for devices, PHYSICALLY TOUCH touch the HS820 to the phone.
I couldn't get my HS820 to synch with my new Blackberry Curve the normal way and ultimately got it to synch by going through this process.
