Spoon HT lead Earth point

[Tmus]

Yo

where do you guys put your Earth point for the Spoon leads?

I thought it should be where the small earth lead goes to the front of the car?

I see some ppl have put it on the stud where the spark plug cover goes on.

 

[teg boy]

the 4 studs where the plug cover bolts

the 4 studs where the plug cover bolts

Correct.

As in this is NOT the way.

Albeit it is cleaner, but there's no direct contact to the motor because the valvecover is insulated by the gasket and the 4 grommets in the four corners, not to mention the plastic cover for the cam gears.

Does it really make a difference? Some have reported the car responds better.... so I guess Honda put it on the bottom right (if standing in front of the car) stud for a reason....the metal stud is actually connected to the cylinder head.

It is the one directly LEFT of the current location in the above pic.

 

[jime64871]

all 8 studs connect to the camshaft caps and not directly to the cylinder head. There's 24 bolts directly underneath the valve cover that connect the camshafts caps to the cylinder it self.

It's a good argument of where to place them. But i've mainly seen them under the spark plug cover. grounded on those 4 bolts...

.

Yes and what exactly are the camshaft caps connected to?

that`ll be the head





The head-bone connected to the neck-bone,
the neck-bone connected to the back-bone
The backbone connected to the thigh-bone
the thighbone connected to the kee-bone

so "one directly LEFT of the current location in the above pic" is where Original Earth point is anyway.

so...should i put it there and Sandwich 2 connectors or Put in the 4 studs as you said "correct" to.

but i've read that it is not good to "stack" connectors?

So spark plug cover studs it is, hidden away tho...doesn't look as "tuned"..

The outer 4 and inner 4 studs from the valve cover aren't connected to the head directly like mention above.

The 24 studs once removing the valve cover are....

 

[RagingAngel]

The point I was trying to make really is that the connection is more direct than the point shown in the picture above...which is really intended for the DC2 throttle bracket.

From one grounding point that is more insulated to the one that the factory uses - there is a difference - correct?

You either stuff it under the cover, or you go to the top right corner. Normally, if using the Spoon grounding kit as well, the straps as you said do not stack.

yeah i can agree with that!

Ragingangel: Thats my pic!! hehe

My connection is grounded there as I have a line that goes to the radiator plate and another line directly to the Buddyclub condenser.

Spark cover studs holds the rocker cover down. So isn't the rocker cover grounded to the head anyway?

Would it benefit more to move the connection to the head?

 

[jime64871]

who knows...
unless you R&D it.

 

[RagingAngel]

There's no need to "R&D" it. Just use a voltmeter and test for resistance. Maybe we'll all be surprised at the "wrong" grounding point vs. the factory grounding point.

Some have gone as far as grounding it on the cylinder head via one of the intake manifold studs.

I have explained it the best that I could as to why the DC2 throttle bracket hole is not ideal and while I would love to bust out my voltmeter to back it up, my cars are some 14 hours away via plane....

I don't know guys... all this talk about grouding points and there still doesn't seem to be a firm answer for everyone.

I mean, sure there is a direct grounding connection on the Plug cover thread, but since all 4 plug cover studs are hold the rocker cover down, that means the rocker is also a grounding part. Otherwise, we're saying the factory grounding point on the rocker cover is HONDA's mistake...

You'd also get corrosion on stacked points if its has moisture. But a simple clean is as easy as removing a bolt.

I've also attached some more pics of some direct connections from my buddyclub condenser... if theres a flaw, please let me know...



Heres one on the tranny and chassis. Also a direct connection to the radiator.

Direct connection to the head

Direct connection to the rocker cover + buddyclub condenser relocated to the mid firewall.

The rocker cover is directly insulated especially where you have grounded it on the throttle bracket hole. Also, you'd be relying on the EIGHT studs (not forgetting the ones under the wire cover) to attain grounding.

The cover is isolated from the head via 4 points

-Its rubber gasket that runs the entire length of the cover
-there are also 4 gaskets under each sparkplug hole
-the plastic covers that hide the camgears
-all the rubber gaskets under the rocker cover nuts

The thing about voltage resistance/grounding is that the closer you are to the actual grounding point, the better the ground is.

What you've done is make the insulated rocker cover that is aluminum which is not as good as a conductor as the steel stud in question - to act as a grounding point.

Remember it is ALSO isolated in the manners above.

IIRC, stacking ground points from an EE perspective also raises the resistance. I neither have the knowledge or the formulas at the moment and I'm waiting to be corrected if that's the case.

What is shown on your last picture is known as dove-tailing or daisy-chaining. Multiple points stacked with multi-grounding locations.

Does it still work? I'm sure it does....but is there a better way to do it. According to EE theory and practice, yes.

Actually I was talking about those 4 plug cover threads in the begining...

Atm, theres a direct line from the Buddyclub condenser to the SPOON leads where its bolted down on the rocker cover... This is ok I presume? But if my condenser line wasn't there, then it would be a different story correct?

 

[RagingAngel]

I would hook the condensor wire to one of the corners of the cover instead.

 

[jugbugz]

Will do!

Or I'll put a longer line to run it inside along with the plug cables and ground it onto the 'Plug cover thread/bolt'.
