Car Forum / Ford / Ford Explorer / April 2006Where 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.

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. > >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. 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 Johan B Former 1DP1375 :-) > In fact there are ways adding a ground in the wrong place > can hurt by creating what is call a ground loop.
