My car radio banned the resister r9 and but the person fixing it tellme he does not know wich resister to put in cos it doesnt have colour code

This is quite tricky if you do not have the schematic diagram. But if this is on power then it could be used as a fusible resistor. Typically they are 1 ohm 1 watt. But you could try with 10 ohm 1 watt to see the progress.

MCS 160 Boston Subwoofer ZD3 Zener Diode Value

ZD3 is a 18v zener. Also check the surface mount resistor on the back of the board that is attached to ZD3, I think it is R9. Should be 10 ohms. This resistor sometimes opens when the diode goes short.

Hitachi charger uc18yrl value of resistors: r3, r8, r9

the values that i read:
R3 = 4.7 ohm, savety 1/4 W
R4 = 47 ohm, savety 1/4 W
R8 = 1 k ohm, 1/8 W (seen on working PCB)
R9 = 0.47 ohm, savety 1/2 W
these resistors and Fet: 2SK2996 were defective

No power going to coil pack

Hi, first check fuse 19 inside the truck. If that's good, try disconnecting the capacitor from the wire--it may have burned up inside. If still no-go, check the resistance across the primary (red versus each tan wire) of each coil in the coil pack. Resistance should be at least 1 ohm, more like 2 or 3 ohms. If not, replace any shorted coil. Please let me know if you have questions, and thanks for using FixYa.

How do i know if its my temperature sensor, or heating elemnet that isn't working?

HI. You can administer a simple continuity test on the element to confirm failure. A burned out element will show no continuity, when measured. As for the sensor, A simple resistance test can confirm functionality in this case.

The most common oven sensor should be approximately, 1100 ohms when at room temperature. The others may be close to as follows:

100°F - 1143 ohms
200°F - 1350 ohms
300°F - 1553 ohms
350°F - 1654 ohms
400°F - 1753 ohms
500°F - 1949 ohms

If the sensor resistance is lower than 1100 ohms, This will confirm that the sensor is faulty. If it is higher than 1949 ohms, this will confirm failure, as well. replace it in this case.

Stirrer is not turning. Kernels burning

check first the fuse of the motor. if not busted, measure the resistance of the motor using the DMM, digital multi meter. you should get a resistance reading of 100 Ohms to certain Kilo Ohms. if no reading replace the motor. if the resistance is in mega Ohms replace it as well.

R517 of main board is burned out - TV won't turn on.

lo que puede hacer es medir el ohm de la resistencia y * 2 pero desde el terminal hasta la mitad de la resistencia

I have a burned out resister which I need to replace.

R11 = 3.9 K ohm 1/4 w If Q6 burned,change by NTE5657 ( 600v)

I have the same problem, but it is open.  The color code Brown - Green - Brown - Gold.  If it is a resistor, the value must be 150 ohms +/- 5%.  To confirm the value, I open the working trimmer and remove one leg from the circuit and measure resistance.  The meter reads only 4 ohms.  Therefore, I think it is an inductor (150uH +/-5%), not resistor.

Sometimes you will need to reinforce the whole circuit with new soldering metal as well. Mass produced circuitry sometimes uses very little of the stuff or uses soldering metal of poor quality.
