Re: [DML] Re: Capacitors, and "Ground Bus"

[Marc Levy <malevy_nj@xxxxxxxxx>]

I added new grounds from the battery to the alternator, because when my 1000W stereo was at full blast, the engine ECU would run the engine lean.

in *MY* case, the voltage drop across the "stock" electrical path from the alternator to the battery was too high..  as the amperage went up through that path, the voltage drop also increased, causing a LOW VOLTAGE situation at my ECU. 

My problem has NOTHING to do with noise.   The only capacitor I added to my car is connected directly to my sub-woofer amplifier.  This is a "stiffening capacitor" that allows the amplifier to get large amounts of current from the capacitor instead of the battery on demand.  Adding the capacitor had NO IMPACT on my ECU issues. 

Once again, I am not faulting anyone who wants to add a "ground bus".  I admit to adding grounds in my car and many others, so I am not sure what point you are trying to prove by mentioning it yet again.   The fact remains, you can replace all of the fiberglass in the car with copper, and it will not replace the function of a capacitor.

Capacitors were Lotus/DMC's unsuccessful attempt to quiet the electrical system down. It didn't work -- electrical noise has the EFI boys pulling their hair out. The only way they have managed to get their modules to work right is by regrounding their vehicles.

You too have admitted running new grounds to try to sort this mess out. Not to be the bearer of bad news, but that puts you on our side of the sandbox....
