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. -- Neil Nicholson. 1981 Air Cooled Westfalia - "Jaco" http://web.mac.com/tubaneil Engine swap beginings: http://tubaneil.googlepages.com/
