already a dis-similar metals issue inside the pump, made worse with poor lube
flow along with piston to follower hammering...which is most likely mixing in
metal debris....again, into the poor flow lube/coolant fuel.
If the grounding isn't done right, or if a subsequent electrical grounding compromise
happens, then ripe for additional maladies being heaped on top of an already
poorly designed coolant/lube cavity
At the kinds of voltages (it is above the low voltage threshold to require
additional safety measures) there is another potential issue and that is induced
voltage potentials
Does anyone know how the wiring is protected (both from and to) ? Foil and/or
braided ground or is it just single conductor wiring?
Folks should read up on the initial DeathCool (DexCool) issues with voltage
potentials created in the cooling systems of the GMT400 series. Metalization
of the coolant from the acid etching (OAT, organic acid technology, coolant).
Can't find it anymore, but there was a magazine article showing HOW2 check the
condition of your OATs/HOATs coolant with a DVM and IIRC, 6VDC were measured
on some (coolant...liquid...to ground).
