Ok so I got a sateliite radio for my car. And i plugged it in to the cig lighter and it sounds like a buzzing that goes faster and higher depending on my rpms.

I suspect its a bad ground somewhere.. but have no idea where to start looking.

Off the neg terminal of my battery is a red wire that looks like its grounded to the tranny?? Would that make the buzzing noise?

Should I ground the battery to the car frame instead?

ty!!!

 

The stock ground would be one lead that runs from the batt. to the chassis and then to the engine, [tranny], it sounds like someone "beefed up", [added] the batt. to engine ground.
If there is no batt. to chassis ground, install one, the car needs both the batt. to chassis and batt. to engine grounds.

Where is the satellite radio ant. and how/where is the ant. lead run?

What is the MM&Y of your car? 94

 

you know i do get zapped a lot when i close my door after i get out.. hmmm

I will check out the ground from engine to chasis and let you know!

its a 1997 hatchback cx

antenna is on the dashboard

 

Getting "zapped" has nothing to do with the cars grounds, it is a static charge. 94

 

try;
a grould loop isolator
noise filter on power wire
new ground(good bare metal chassis ground)
Make sure battery, block and alt are grounded good.

 

upon further inspection, the ground wire from block to chassis is really really ugly! ordered a new one, hope this works WOOOO

 

ok my new ground wire did not work. its still there.

let me get this straight

there are 3 grounds.

battery to chasis (like 4 inches of wire)
battery to block (connects to tranny?)
block to chasis (dip stick area to front headlight chasis area)

is there anything im missing?

 

You are getting engine noise... most likely from a cheap satellite radio kit, right? why not get a nice aftermarket radio with integrated satellite radio?

 

when i am in gear and lift off the gas the static noise crap gets REALLY loud until i hit the gas again! yea you know taht is a good idea.. im gonna return this stupid thing and get a nice head unit
