[DML] Re: Inadequate DeLorean Grounding Identified (Big Red Circle)



Correction: Harold's Message #85598 is actually rather mellow -- he's not part of the current running around with your hands in the air crowd (we'll let Tom take his place).

Harold does have a loose DeLorean wiring harness he can use to verify that the inertia switch is grounded via the ground junction behind the central HVAC duct.... (I've already unwrapped #2508's wiring harness to discover the same thing, but Harold could ring it out with a meter to prove it to anyone who doubts my research).

The problem is only seven ground wires leading back to the rear bulkhead bolt -- there simply isn't enough wire on the negative side. There is a terrible disparity between electrical cross section on the positive side and on the negative side. That is why the DeLorean electrical system is so ridiculously noisy (which is giving the EFI boys fits BTW: the only way they can get their Megasquirt modules to work right is by regrounding their cars too).

I choose to stand with Rob Grady, Dave McKeen, and the owners I have assisted, who not only clearly recognize the problem for what it is (it takes a brave man -- or a naive one -- to claim that the DeLorean electrical system is not problematic on its best day), but who also are just plain more mellow about the problem, and about its remedy.
