[Vwdiesel] Dying Glow Plug Relays???

[Area31 Research Facility]

Miser,

With separate #6 AWG wires and proper generously sized crimp on eyelet
connectors, all copper directly to a battery the four glowplugs draw a
combined 100 amps measured when they are starting up cold.  This current
drops as their resistance grows with temperature.  That is 25 amps x 12 or
300 watts per plug.  The wimpy single #10 AWG wire that VW uses to run
gloplug power to a common wimpy copper bus cannot support that much current
without significant losses, so heat will be wasted in the VW wiring, but the
current is still pretty high on turn-on.
