- My model of MX-5 is: __1999 NB
- I’m based near: Sheffield
- I’m looking for technical help or recommendations on: __Electric fan
I have a question on the electrics on an 1998 / 99 NB 1.8iS. The electrics on this vehicle are quite confusing. The Haynes manual passenger compartment fusebox is nothing like what is actually there. I started looking as I was trying to find out if my electric fan (non-aircon model) was working. I’ve had no over-heating issues or movement of the temp gauge towards the red from normal, just curious. I’ve connected a battery to the terminals and know it works fine but cannot for the life of me work out how it is triggered. The little diagnostics box on the right hand side under the bonnet does not have a ‘test fan’ connector even though all circuit diagrams state it does. I understand that there is a sensor on the rear of the engine near the heater pipes that is supposed to trigger the fan but it has never been heard to run even when the engine has had a good run and immediately switched off. The passenger fuse box according the Haynes has a 30A big square fuse but my fusebox doesn’t and most of the actual fuses are in different places. It seems that the electrics of this model are different to all other NB’s. Does anybody know of a circuit diagram that is accurate for this model?
