Question about BMW M6

2 Answers

The manual for my '07 M6 says to charge the battery using the posts under the hood. I have located the "+" post but it doesn't look like what I am use to seeing. Where should I connect the positive and negative cables so I can put a trikle charge on my car. I have had it stored over the winter, only starting it once, and things are now dead. Thanks

That terminal is up front because the battery is in the trunk and less accessible. You can hook the charger up positive to the underhood post you mentioned. If there is no negative post shown in the manual, keep in mind that the whole chassis and engine is grounded. Any exposed metal parts should work - a shock tower bolt for example.

You can hook the charger directly to the battery in the trunk too, but the above should work just fine.

On the newer model cars they have started putting the battery under a myriad of plastic covers to make the engine compartment look cleaner. The "+" post that you have found is directly connect to the positive terminal on the battery. Put the positive cable on that post and then the negative on a bare bolt that is connected to the frame of the car, I would use the one on the sway bar if possible.

How do I charge the battery

Just be careful NOT To burn out the computer brain when charging. Remove the negative cord from the battery post. Set the Positive charge line on the PLUS post and Negative on the Minus Post. Do not have a key in the ignition either.

07 RAV4 4cyl. plugs.. correct NGK # and gap

Go to Rock Auto.Com

Napa is okey & have NGK but way too expensive

Use the NGK web site,then Rock Auto site to find
correct plugs

You really need an owner manual for that & also
look at the label under the hood to see if there is
some mention of plugs

This is a social web site,so take things with
a grain of salt as they say

Most people are at home with nothing to do &
some vheicle knowledge

Where is the post under the hood of a 1991 BMW 535i that I can use to charge the battery?

Did somebody tell you there was a post under there? They are talking about the battery post. If your battery has side mount terminals, it has no posts, and the side mounts are a nightmare to charge up. But it can be done. Is the battery getting weak? Did you check the water? Check the electrolytic stuff to see if it is worth charging. One of those floaty ball things. Walmart will check it for you for free, they like selling batteries. Your alternator should be charging the battery, unless it has been sitting a while. Hope this helps.

Car won't start, how do i charge the battery? for a 2006 chevy cobalt

I would recommend hooking the charger up right to the battery which is located in the trunk under the carpet.
You can hook up the charger under the hood to the remote jumper postivie post and to any ground. If I remember correctly there is a strut bolt right next to the remote positive post.
Either way will work but I'd go with the first one.
