Where are the ground straps
 

Where are the ground straps?

I have a 99 Explorer Sport V6.

Recently I found the braid ground strap from the frame to the
body, nearest the drivers door jamb had rotted out.
I see a similar jumper on the passenger side is also in poor shape.
I'm about to replace them.

Are there other grounding jumpers?

From the engine block? From the exhaust?

Where are they located?

I hope replacing a missing ground will reduce
some of the injector noise that is getting into the AM radio.

Where are the ground straps
 

Just measure the voltage drop between battery/engine/frame etc. and make
your own

You can never have too many good grounds

Hi JohanB

While that may help fix a starting problem, that is not my concern.
Measuring the voltage drop will tell little about the Radio shielding
and noise grounding. For example a missing ground strap on the
hood or exhaust will make a major difference to radio noise pick up,
but have no effect on battery voltage drop.

>You can never have too many good grounds

Yes adding a lot of grounds might be a good bruit force
solution, However I had hopped the factory had sorted out
what was best and all I had to do is fix what had deteriated.
Or been lost to a service tech who didn't think it mattered.

In fact there are ways adding a ground in the wrong place
can hurt by creating what is call a ground loop.

Does anyone out there know where the factory frame, to body,
engine and exhaust ground straps where when new?

Maybe I should have finished the " How to become a licensed radio amateur"
study guide, but instead I scratched my head and stopped reading after page
3, jumped behind my 11 meter radio, switched the 500 watt amp on and waited
till my neighbor came yelling that he had no color on his TV

So as far as my knowledge goes its " bad grounds will cause radio
interference" and you just install ground straps @ the part that is causing
and receiving the static.

If you were expecting that Ford had your Explorer all tricked out for
perfect AM reception I have to disappoint you.
Except for a ground strap on the hood hinges on some models and a
suppressor on the coil pack there is nothing as far as I recall .
But then again, haven't really been paying attention

Good luck
