Thermometer cable (Gilera RC 600)

Postby ijuvone » Tue Jul 15, 2014 7:32 pm

Hi,

Thermometer isn't working any more. I checked the cable and it was broken. I noticed that there is a resistor. It looks like it has been added afterwards, connection doesn't look very reliable. What is the purpose of that resistor? Is it necessary? If so, I have to find a new one, it can't be soldered together with the wire.

I think that the resistor doesn't exists in RC 600 wiring diagram? I'm not very competent at these electrical issues :?

Fortunately both fans and fan switch are working properly.

That seems to be the Luigi style ;)
I think we had this dicussion some years ago (maybe it was in the old Gileraclub forum)
Also the Saturno has a gauge with or without this extra resistor.
I had a funny overheating probem at those times and thought it was a problem with the gauge and /or the resistor.
But it was something completly different.

Looks like Luigi has once decided to add this resistor.
Maybe because he used a different gauge from that on.
Or because he thought the temperature which was shown, was to somehow to high.
We will never find out, i think ;)

Ok, thanks. It's good to know that there can be this kind of special solutions. Luigi seems to be very creative :wink:

It looks like the wire at the resistor is broken.
You know how to find a new resistor?
The value of the resistance is coded in th color rings on the outside.
Red is 2.... a sfar as iremeber ;)
The Gold ring at the end ist the tolerance. 5% if i .....
You will find the code somewhere in the net.
If not, drop me a line. I have it somehwere here around.

Yes, you're right. I have to find a new one. I think that I can solve the resistance e.g. with that calculator ==> http://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-resistor-color-code-4-band. I have also a simple multimeter to measure the resistance. I bypassed that resistor so I will get some temperature readings.

Thanks anyway.
