I thought that Freecell was referring to the radio equipment in the car, but now I think he means ANY equipment: i.e. radio, amp, FILTER, ECM, ALTERNATOR, SENSORS, CAR BODY, etc.
You wrote that you, "...shielded and grounded the computer, and ran shielded wires for the cam and crank sensors." You also mentioned that you grounded the alternator, and that, "the vehicle is grounded as can be."
I believe these are some of the double grounds he is referring to.
Finally, Freecell wrote:
" the solution is to use a central grounding point or "sink" (and use) the ENGINE BLOCK as the central grounding point connection."
Evidentally, the engine block functions as the ground point for the ECM System, and this is what Freecell is referring to as the "reference ground." So...(I'm assuming here)you need to attach the negative leads from the radio and amp to the engine block and not the negative battery terminal. Also, maybe you should unground the filter. None of the equipment in my base station is grounded (although everyone tells me it should be), and it works just fine. So...(again I'm assuming) there's probably no reason to ground the chassis of the radio or the amp or the filter in your mobile either.
I hope what I said here is right. If I'm wrong, I know Freecell will tell me. LOL.
