Resistor Identification or circuit diagram for wireless subwoofer
I was having an issue of the subwoofer cutting out occasionally, until recently when it just altogether stopped working. I took it apart and noticed that there are two burned resistors. My problem is, I am unable to identify the resistors due to discoloration. There are no other resistors that look similar to use as reference nor have I been able to find the PC board circuit diagram online. I am hoping someone has one of these units and can look on theirs and tell me what the value of the resistors are for R08 and R09. Any help is GREATLY appreciated. Thanks in advance.

You should check the new cable wiring connections. There is a resistor in that microphone that connects to the channel button circuit, it is (electrically) between switch 5 (up) and pin 3. If this not present then it may be causing your issue, IT is also possible that the diode for that circuit (located on the main board) got damaged when the cord was cut. diagram: http://www.cbtricks.com/radios/realistic/trc_476/476_print.htm
Usually, when the fan works only on high speed the issue is with the blower motor resistor. It will be located under the dash close to the blower motor itself. It will have a multi-wire plug and feeds signal to the blower motor. An updated resistor maybe available in which case a slightly larger hole will have to be cut for the new resistor. This is not a difficult proceedure, only a couple of screws are holding the resistor in place and most resistors are resonably priced. I recommend you buy the resistor at the dealer, this is a case where you get what you pay for.
Good luck, hope this helps.
The color code is as follows: blk = 0; brn =1; red = 2; orange = 3; yellow = 4; Green = 5: blue = 6; violet=7; Grey = 8; white = 9
Unfortunately, if it is wirewound, they usually printed the resistor value on the body of the resistor. For sure it shouldn't be glowing. Sorry I can't be more help, but without a schematid, can't do much else
If the resistor is used on a detection circuit, any standard 1/4 watt resistor will work fine. The function of such resistors are to be placed at the end of the line (most distant part of the detection circuit) and the purpose is simply to prevent a undetected short path in the line from going undetected. Such a circuit allows for the detection circuit (also called a loop) to activate both on a short or open in the circuit.
