House please, my radiator fan fuse always blow up and my electrian now connected the fan direct from the ignition and also advised me to disconnect the radiator fan switch as well.

Now my question is there any implications to the connection direct to the ignition?

Yes, there are implications.

First of, you should not have agreed with the direct fan connections of the radiator fans.

LIKELY CAUSES OF THE PROBLEM

As long as the fuse keeps blowing, this tells me there's either a short to ground problem, or so.

There's a current flow that is way beyond the carrying capacity (amperage) of the existing fuse that keeps blowing.

One or two of the electric fan motors must have burned out. I mean the windings inside the motors are susceptible to heat. They loose their insulation when huge flow of current passes through them, or one or two of the fans are stuck by a wire or debris.

Check the fans blades to see if they are stuck(not moving).

You have to troubleshoot that car properly to get to the root cause of this dilemma.

This maybe not be something within your skill set right now, seeing that the electrician, has just left that part of the diagnosis.

So, here are the implications, off my head.
1. The lifespan of your electric fan motors is being cut short here, because they tend to run, at every second the ignition switch is turned to accessory.
Be prepared to start replacing fans.

2. Your car's fluids are meant to reach a certain operating temperatures, before efficiency is achieved.
Now, the fluids such as trans fluid, and engine oil, does not get to their normal temperatures.
This in my view, would increase the viscosity of the fluids you use.

3. The lifespan of your battery is cut by almost 1/2.
Seeing that you keep running the fans off of the battery, the alternating system would have to keep recharging the battery to its recommended state of charge(SOC).
I hope you do know that what kills batteries is the number of discharge and charge cycles the batteries undergo within a short period of time.

4. Although, this is rare, but its a possibility, that your car could catch. This has to do with the inability of the fans circuits to bear the large current surge in it's wiring harnesses and connectors.

It gradually starts with melted wires, and smells of burning insulation, before you know it, BOOM! That's a fire.


Finally, retrieve your car from the electrician, if he can't figure out what the problem is.
This is similar to instances where people connect their fans directly, to conceal an overheated engine.



Hope this gives you some succor.

PS: What car is this?

Problems maybe emanating from any of the circuits on the fuse assembly area at the front.

Are you sure the electrician is using the right fuse amperage?

Could you check if the two fan relays are shorted (bad)? Swapped a known good one and see how it goes.

Okay thanks, l will change the electrician and look for a good one who knows about the job well.

Are you Naphew?
I know someone by that name.

To your question, I have once observed the discovery of burnt/ melted wiring running to the fans. I'll suggest you peel off any insulation and trace radiator fan wiring. It's a good start to solving a rather common problem.

Thanks, today l got another electrician and he removed the relay and connected the fan back the way it should be. Though am observing it.

The car is Honda baby boy. It has been reconnected back the way it should be.

Thanks for the update sir!

Is there anything wrong connecting motor fan directly from second ignition

Henryjp:

Anything that is not recommended by the manufacturer that is connected externally as extra load to your car wiring system that doesn't cut fuse has potential to set up a fire on a car so do the needful before it is too late .

Okay noted! But formely the motor fan is connected wit a fuse in a way that once I start the vehicle the fan will be rolling! And it never overheat.

It will be burning out the starter key soldering points
