Ibm 61h2500 p/n 61h2471 sw1 and sw2 problem

Rheem RTG2 42 Troubleshooting Manual Error Code 99

do below once if the code comes back replace the fuser continue reset cause fire ruining a perfectly good day


1. Turn ON the main power switch (SW1).
2. With the Utility/Counter key pressed, turn ON the power switch (SW2).
3. Press [Trouble reset] to release a trouble with [OK] displayed.
4. Turn OFF and ON the power switch (SW2).

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

do this once only. If the code comes back then the fusing unit the hot part is broke, it could be a thermistor, heat fuse, heat lamp or the board that controls it. Have a tech look at the fuser? Do not continue to reset or a fire could occur and that would ruin a perfectly good day :) Code is for the FUSER!!!! (HOT PART)



1. Turn ON the main power switch (SW1).
2. With the Utility/Counter key pressed, turn ON the power switch (SW2).
3. Press [Trouble reset] to release a trouble with [OK] displayed.

CPU
Supports AMD Athlon / Athlon XP / Duran (Socket 462) processor.
(Socket 462 = Socket A)

Supports from 1100MHz to 3000+ model.

VIA KM266 Pro motherboard chipset - Front Side Bus support of 266MegaHertz.

http://en.wikipedia.org/wiki/List_of_VIA_chipsets#Slot_A_and_Socket_A

(Same specs as a VIA KT266A but with Integrated Graphics.
The 133MHz FSB support shown is doubled. AMD processors are 'Double-pumped')

VIA KM400 motherboard chipset -
FSB support of 266MHz to 333MHz.
(Same as KT400 but with Integrated Graphics)

VIA KM400A motherboard chipset -
FSB support of either 266MHz, 333MHz, or 400MHz
(Same as KT400A but with Integrated Graphics)

Looking at the Bottom/Right corner at the CMOS battery;
There are THREE sets of jumper pins to the bottom right edge of the CMOS battery.

6 pins towards the outside edge of the motherboard, 3 pins to the inside of the motherboard. (Left side of the 6 pins)

On the 6 pins in a row configuration, the top 3 pins is SW1.
The bottom 3 pins is SW2.
The 3 pins to the inside of them is JBAT 1

In the 3 pins for SW1 the bottom pin, or pin closest to the bottom edge of the motherboard, is Pin 1.

Same for SW2. The bottom pin, or pin closest to the bottom edge of the motherboard, is Pin 1.

Jumper on pins;
SW1 pins 2 and 3, SW2 pins 1 and 2 = 266MHz FSB support
SW1 pins 1 and 2, SW2 pins 1 and 2 = 333MHz FSB support

For the KM400A (KT400A) motherboard chipset;
SW1 pins 1 and 2, SW2 pins 2 and 3 = 200MHz FSB support

1) What is the model name, and model number of the AMD processor you are going to use?

2) What kind of Thermal Paste are you using?

3) What are you using to clean the bottom of the Heatsink with, and is the top of the Processor clean?

4) Are you following Anti-Static Precautions?

• Locate the MB8719 chip that is right behind the channel selector. Wire a SPST switch from pin 10 to ground and another from pin 11 to pin 12.

Two Way Light Switch Wiring Have you ever wonder how a lamp that is used to light up the stairs of a building is connected to the two switches that controls it from either end? These two way switches have a single pole double throw (SPDT) configuration. Each has a common terminal (COM) with a pole that can be switched between position L1 or L2. The two way light switch wiring can be implemented by using 2 different methods. Both of the methods used are described below.



The first method as shown in the figure above have the COM, L1 and L2 of both the SPDT switches connected together. For incandescent lamp, the recommended wire gauge used is AWG #18. The LIVE AC Source is connected to L1 of SW1 and one side of the load is connected to L2 of SW2. The other side of the load is then connected to NEUTRAL of the AC Source. With this configuration, the lamp will be turned ON when one switch is at ON position and the other is at OFF position. If both switches are in the same position, the lamp will be OFF.




The other method is as shown in the figure above. In this configuration, the L1 of both SW1 and SW2 are connected together. Similarly, the L2 of both SW1 and SW2 are connected together. The LIVE of the AC Source is connected to COM of SW1 and one side of the load is connected to COM of SW2. The other side of the load is then connected to the NEUTRAL of the AC Source. With this configuration, the lamp will be turned ON when one switch is ON and the other is also ON. If both switches are in different position, the lamp will be OFF.

Take note that as the installation involves mains power supply, only those who are qualified and have electrical wiring knowledge should do this wiring. When doing the wiring, it is recommended that the power supply is disconnected from the load and the switches.

SW1 is a single overhead cam. SW2 is a dual overhead cam both have multi port injection.

mfi = multi port injection
tbi = throttle body injection
the way to tell is look on the intake plenum and see if there is a "carb" sitting there. That's tbi.
Intake plenum with 4 or more fuel lines going to each cylinder is a "MPI" (multiport) system....accordianman

I don't know the syntax but you could easily do this with setting the switches to a constant, then adding them up. The number set would need to be something so that there would only be one solution...the one that you were looking for.

sw1 = 1
sw2 = 2
sw3 = 4

If sw1 and sw2 is both on, but sw3 is off, the number would be 3
If sw2 and sw4 was on, the number would be 6
If all were on, the number would be 7, etc.
