Unhappy Tach (Electrofan???) Problem

Hi Guys

Wonder if anyone of u can help.

I was under the hood one day with the engine running, when I noticed some wires burning.

It turned out to be the wires from the main fan temp sensor, I believe (it is on the engine with 2 prongs).

I swapped out the sensor (USD10) and checked the wiring loom.

I stripped the wires all the way back coz they were burnt internally, up to the point where the wires were good. The I cut off the burnt/shorted portion and spliced some new wires.

Now, fuse #10 blows upon turning of the ignition key switch to position 2. Even with the wires disconnected from the sensor, the fuse still blows.

I lost my tach coz they work off the same fuse.

Is there a relay/switch that could be responsible for this problem?

It seems that the electromagnetic fan is not coming on. It is just freewheeling.

Help guys...

Mmm...

Sounds like there may be more burnt wire than you found. If there was enough current to melt the wires near the sender, there was enough current to melt them in other places. This could be giving you a short circuit.

Interesting thought, Neil.

In that case, would you happen to know where the wires from the sender lead to? A switch or relay, maybe? Or do they lead to the ECU?

Tks for yr quick reply.

Sorry

I don't know where the hookup is for these wires.

Good luck
