How to coonect a trickle charger

[Boomerjake]

Hi
Again I am showing how un technical I am , I have bought a trickle charger and need some help in connecting.
I guess I connect the + to the battery and then it says I should connect the negative to the engine block (engine a long way away from battery). What else can I coonect the connecter too.

Thanks
Greg

Hi, Greg.
You have several options.

If your conditioner kit came with the flyleed for permanent installation,
then you can connect the black wire to the negative (GND, - ) terminal of the battery and
the red one to the positive ( + ) side like this.

You should disconnect the battery by removing the 'GND cable' from the battery negative post
before installing the flyleed in order to prevent electrical short.

The 'GND cable' is the thick black one with yellow line at the left side of the above photo and
it's the one connected to the chassis frame at the back of the battery case.

Please note that by disconnecting the battery, you will loose several settings including
all of the error codes except for the ABS (depending on the year model),
radio setup, ECU fuel trimmer, etc.
It is best to carry out the 'reset ECU' procedure if you know how to do it but even without it,
ECU will re-learn the fuel trimmer eventually by driving your NSX in all sorts of conditions but
just takes longer than resetting it.

Before reconnecting the GND cable to the battery post, please wear ear protection and
be prepared to arm/disarm your alarm system.
As soon as reconnecting the battery, it may trigger the alram siren.

If your battery is completely flat, it is best to take the battery out and use the alligator clip like this.

This is for the protection against possible hydrogen gas generated with the high current passing through
the battery cells so you want well ventilated area.

Also, when the battery is completely flat, it may generate high ripple current depending on the
conditioner/charger you are using.

For temporary top up of your battery using your equipment as a conditioner,
probably it’s easier to access the jump start terminal inside the engine bay than
accessing the battery directly, especially if you have spare wheel kept under the bonnet.

The positive terminal is inside the fuse box near your coolant header tank so
open it and connect the red cable like this.
Please be careful not to touch any metal other than the jump start terminal with your red alligator clip.

For your black alligator clip, the official method is to clamp it to the Throttle body (TH body) with
the area marked as ‘ – ‘ as in the photo.

However, the design of TH body is different depending on the year model and it may be bit tricky to
clamp it securely.
For this reason, I normally just clamp the TH body near the brake booster vacuum line like this.


On the later model, you should have no problem clamping the TH body at the ‘ – ‘ marked area because
Honda modified the design and created cubic shape jump start post for much secure connection.

You can also clamp other metal parts (engine, gbox, chassis) for the black alligator clip but
it's probably easier following the above procedure unless you know how the parts are
connected each other.

Kaz
Thank you. Just did as you stated above and all on charge, is it safe to keep the cover on the car while the charger is connected.

Thanks again
