Silly question,

Can any of you tell me where the factory ground strap is located? I've received the Pettit upgrade to this (it's free) and I'm such a non-mechanic that I'm not sure where the factory ground strap is located. Is it the strap from the manifold to the chassis or is ther another strap that I'm overlooking.

Thanks!

 

Should be: Firewall to passenger Upper intake manifold. Look for one of the Engine hooks.

jc.

 

can u tell me how you managed to get one of those FREE?

I called AND emailed them w/ my info and never received one.

 

I ordered several items from them and asked for it. In their new catelogue they state it's free and just call for it.

Good luck.

 

Yes I believe it's one of those things that's free but you have to pay shipping on it.

 

Yes, it's free but you have to specifically ask for it. I forgot to ask for it when I ordered my stuff from Pettit, but I just made my own grounding wires...

 

Ground straps are cheap. You can find them in the HELP section of any auto parts store. 5 min. install.

 

The primary engine ground is a large black cable which travels under the fuse\relay box on the driver's shock tower to the bottom of the motor by the trans. It often gets oily and needs to be cleaned. The same cable grounds just under the relay box. The Pettit kit goes from the neg battery post to the driver's shock tower just above the relay box. There is also a ground from the intake to the fire wall. There is an updated part from the Mazda TSB which upgrades this ground wire. It eliminates the push spade connector which is prone to melting. There is also an exhaust ground to the subframe just prior to the axle. Usually pretty corroded and needs to be cleaned.

 

What he said! I couldn't find the primary engine ground (the one in the Pettit diagram) until I went under the car and looked up from below. The Pettit instructions didn't seem to make sense until I did that, but once I could see what they were talking about it was perfectly clear.

Make sure all three grounds mentioned by rotary-tt are clean, solid connections.

 

You have to jack up the car to that step for the pettit grounding kit. The instructions are not clear but look directly under the spark plugs all the way down and you will see the strap. The wire itself is black with a yellow stripe on it. Use the bolt that is supplied and bolt it directly to the block.
