DRBIT

Hi,

I have a Dolphin Diagnotic 2001 with a rev09 circuit board. The component to the right of the red wire is burnt. Can anybody identify the component and value? Any other info would be welcome.
Thanks.
Dave.

I also thought it looked like 18 Ohms in the photo but I could not find that value. I will probably go with 10 Ohms and see what happens.
I am a bit concerned that, if it is being used as a current sensor, the reason for the burnout may be another component which is short circuit and as it is extremely difficult to monitor the current once it is all reassembled, there won't be much chance of saving things once it is powered up. Might as well chance it thogh as its not much use as it is.
It may be a couple of weeks before I get a chance to sort it out but I will report on how I get on.

It seems to be 18 but the strange thing is that I could not find a resistor with that value manufactured by Visahy...the one more similar is a resistor with a value of 17,8 OHM

check the filter by value, there is not a 18 OHM resistor...

It would appear from the photo that the resistor is either 10 or 18 Ohms and it will be 1 Watt.
I would like a second opinion on the value though.

Hi Diego.
No, unfortunately I have not been able to determine the value of the resistor.
If I find the value I will contact you and let you know. If you could do the same for me I would appreciate it.
Good luck.
Dave.

same problem
by: Diego (rome)

I have the same burned resistor, it is a resistor manufactured by Vishay model WSC 2515 but I cannot read the value of resistance (OHM), did you find more infos about it? If yes please let me know, my email address is diego.verri@gmail.com
Thanks
