The fan turned up today from the USA
.
I've been busy getting the electrical wiring done and have made up the Voltage Switch kit (I'm going to start with only one to switch both fans on full bore, but am doing all the wiring/ relays for dual speed so it can be added later.)
I'm going overboard with all the main wiring and running 85 Amp rated cable for each fan to minimse voltage drops. Even the slightest drop makes a huge difference to the fan speed- I learnt that the hard way in my old 4WD when I converted it.
Tomorrow I need to locate the coolant temp sensor wire at the ECU inside the cabin for working out what constitutes a "normal" running voltage (ie. running temp). I'll then do some monitoring for a couple of days and set my trigger voltage slightly above that level.
I'll also be wiring up the Voltage Switch kit inside the cabin and having a LED mounted inside to indicate when the fans are running. Plus I'm going to install an override switch that can be used if the Voltage Switch fails to switch the fans on manually.
I'm not looking forward to ripping the radiator out for the thermofan install, but I don't see any other way to do it?
