360 Battery and now starting problems

If you want to reset it, there is a switch in the front bonnet(Check manual if you can't find it). You can turn it off for 10 minutes and it will reset.

 

May want to throw a new battery in also.

 

Yep, only running on 1 bank. I just did the same thing because I stupidly left the key turned on (had switched it on to put the top up). I had too much to do headed out for vacation so didn't fix it yet. Got back on Sunday so I will try to reset everything in the next coupld of days and let you know how it goes. If you resolve it let me know how.

 

its under the hood near the passenger side corner
black dial about the size of a 1/2 dollar
turn it off for a few minutes
turn it back on
start car and let idle only for 15 mins or so

 

Did you put a new battery in or just did the reset. Did you give it enough time to reset? I recommend getting a new battery if it's old.

In the good to check department...

Under the car have someone remove the rear access panel, look at the main battery cable that runs to the alternator... that termination at the end of that cable where it connects to the alternator is a known problem... it WILL cause the symptoms you are describing...if there is a fault there, you will see obvious heat damage on the termination..

Any garage can get her on a lift & remove that rear panel.. will take less than 30 minutes to remove/check/reinstall... however if thats the problem you will save yourself more potential issues from gremlins...

 

Yup Hooters should do the trick

 

Always worked for me.

 

I had the exact same problem on a BMW I used to own. In the end it turned out the every time I jump started it, I blew the airbag relay (read: fuse). Apparently it was very sensitive to voltage spikes. It was an inexpensive repair. You might try testing/replacing the relay to see if it fixes the problem.

 

A quick update. I took the time to power off and rest the system. That worked and all is well.

NOTE to self: remember to unplug the tender when doing a power off reset. If you don't, it looks like a bad battery AND you don't get a reset. Oh well, all is good now that I understand what stupid thing I did this time.

 

I had a similar problem after a LONG (6+months) period of storage. Had to replace the battery. Only problem is, after getting everything going and doing a reset again, the alarm siren won't shut off. Tried the red fob, black fob, key in ignition, still no go, the siren does not want to turn off.

Only (temporary) relief has been to disconnect the alarm siren module.

 

Airbag warning tripped by low voltage, requires a scanner to reset.

 

IF he is lucky.


Voltage spikes kill them. Trying to start with a low battery causes a voltage spike.
