DE9108 CHARGER can i have a schematic diagram or a wiring diagram of the electronics or i am wanting to know there is 2 resistors in series 5 watt what r there values 10k 11k or 12kohms they have become pretty warm can not determine colours on resistors 1 resistor reads 11kohms the other 10.2k ohms just like to know the correct values
Can you (carefully!) measure the volts across them with a load (battery) and then the current through them by disconnecting one end, and if the charger is still working OK then they are V/I ohms, choose nearest value. 10k sounds very high, are you sure they aren't 1 ohm or less?
- If you need clarification, ask it in the comment box above.
- Better answers use proper spelling and grammar.
- Provide details, support with references or personal experience.

No diagram needed here Justin, you have enough information with the 1N40, it's going to be a 1N4001 through 1N4007, this line of diodes are Schottky high speed rectifiers, find a diode that matches the physical size to the one you have to tell power, or just put in a 2 watt to be safe, reverse current of 1N4005 in rated at 100 volt, that's the highest of this series of diodes.
You mean the blower motor stops blowing air , the A/C compressor is still engaged ? The temp gauge shouldn't have anything to do with the blower motor .But stranger things have happened on these systems when they are controlled by a electronic module (BCM )
Circuit/System Description
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The ECM sends the temperature data via high speed GMLAN serial data to the body control module (BCM). The BCM then sends the information via low speed GMLAN to the IPC in order to display the engine temperature.
The BCM applies voltage to the blower motor through the HVAC relay. The resistors and the blower motor are in a series circuit. The following list represents the number of resistors in series with the blower motor per particular speed request:
• Low speed--4 resistors
• Medium 1 speed--3 resistors
• Medium 2 speed--2 resistors
When the operator requests High speed, the HVAC control assembly applies ground directly to the blower motor through the high blower motor control circuit.
Do you know anything about automotive serial data communications ? GMLAN Is general motors version of C.A.N controller area network .
Do you know anything about diagnosing automotive electronics ? Using a digital volt ohm meter ? Using wiring diagrams to pin point locations in a electrical circuit for testing ? Do you know what a factory componet location diagram is ? It takes more then looking at fuse's an relays , to see if current is flowing in a electrical circuit .
http://www.bbbind.com/free_tsb.html Free wiring diagrams ! Enter vehicle info. Year , make , model and engine size ! Under system click on HVAC , under subsystem HVAC Controls . Then click the search button , then click the first blue link . This is the blower motor control diagram . Do you know how to read a wiring diagram ?

I have the schematics for this TV but the only resistor I see is label as R4114 and its value is 10K ohms, 5% 3 watts.
I could send you the schematics.
Let me know if you required further assistance.
