Subject:Electrical questions. Radiator fan circuit from 85 Vanagon into 81 air cooled Westy.

Hi all.

If I'm reading this correctly, P 97.66 in Bentley shows a relay that
when energized by "Rad Fan Thermo Sw II", energizes the higher speed
of the Rad fan.

Is the relay there to handle the higher current? Or am I totally
misunderstanding the purpose of the relay?

And when I install the cooling systems' electrical components into my
air cooled Westy, (Jetta Gas engine conversion) could I eliminate the
Rad Fan Relay?

Could I also wire the circuit so when either "Rad Fan Thermo Switch" I
or II is activated ONLY the high speed portion of the fan is
energized?

Are these bad ideas? I was going for simplicity and more reliability.
(no relay to fail)

FWIW, I will wire the fan circuit with an "override" switch and LED.

Many TIA,

Neil.
