I have a new heater with diferant terminals from the old one so not sure how to atach the wires


There is no need to rewire the internal of the heater!
Just bring in the electrical supply to the heater, it can be either 120 or 240 volts.
If the heater you have is like the picture associated with your post, then all then have to do is change the supplied plug from 240 to 120. It comes pre set for 240. That plug is inside the cabinet.

If any other brand, then you need to change the wires at the transformer of the heater. All heaters need to be supplied with primary voltage: 120 or 240. Then the control system is supplied with secondary voltage out of the transformer. The secondary voltage is no more than 28 volts. and these wires are normally colored as blue or yellow.

Secondary power is already wired within the heater. NO need to change where they are. You will only need to deal with the Primary wiring.

There are many varieties of transformers that transform high primary voltage to a low secondary voltage of 28 volts. and these transformers have many wires: primary & secondary.
I will try to make this easy to understand.

If you have a Gas Heater Transformer with these colors:
  • Red
  • Black
  • White
  • Green
Or...
  • Red
  • White with Red Stripe
  • Black
  • White with Black Stripe
  • Green
These are Dual Voltage Transformers, you can bring in either 120 Volts or 240 Volts

If you bring in only 120 Volts...
1st example:
The Red wire will not be used! Hot wire to the Black, and the Neutral/Common, to the white wire. Green to ground.

2nd example:
Connect the Red wire with the White with Red Stripe together and connect these to the incoming Neutral/Common wire, normally White.
Connect the Black Wire with the White with Black Stripe to your incoming Hot Wire, which is normally Black.
Green to ground

If you bring in 240 Volts...
1st example.
1 Hot wire to the Red, the Other Hot wire to the Black, and White wire is not used. Green to ground

2nd Example:
Wire nut the two Striped wires together. then one incoming Hot wire to the Black, the other incoming Hot wire to Red.
Green to ground

Or This is only a Low voltage - 120 Volts Only
  • Black
  • White
  • Green
Or either any of these combinations...
  • 2 Blacks w/Green
  • 2 Reds w/Green
  • 1 Black, 1 Red w/green
This type will only be a high voltage, 240 volts only
Picture below is what a transformer looks like and it is where your incoming supply wires go. The smaller leads with the spade connections will go to a specific location & is the 'Secondary" .

Good Luck

I bought a 2gig kit of memory from Dell for a precision 450 and it's only seeing 1gb in the Bios. Upgraded the Bios and it's still only seeing 1gb


You memory slots have primary and secondary slots. Switch the old memory with the new one and put the 1Gb in the secondary slot.

What are the secondary voltages off the transformer supposed to be?


The secondary voltages of a transformer are stepped down voltages. For example a transformer might be stepping 120 volts AC down to 25 volts AC in the secondary. Which then would be rectified by a bridge rectifier in the power supply and converted to DC Voltage which would be used to bias transistors or tubes and other electronic components. The amount of voltage that is output for use is determined and calculated by the engineers designing the amplifier or pre-amp.

How do i use ubuntu fixing ntfs file system?


Use apt-get from the terminal to install the ntfsprogs package - sudo apt-get install ntfsprogs

Then you can use the tool ntfsfix from the terminal to attempt to repair a ntfs partition.

Example:
* unmount the drive if it's mounted already
sudo umount /dev/sda1 - read below for device naming info
then type: sudo ntfsfix /dev/sda1

Note:
A typical home pc or laptop has 2 or 4 IDE channels as follows:
  • ide0 = primary
  • ide1 = secondary
  • ide2 = tertiary
  • ide3 = quaternary
For example:
  • ide0 = primary master = hda
  • ide1 = primary slave = hdb
  • ide2 = secondary master = hdc
  • ide3 = secondary slave = hdd
  • sata0 = 1st sata device = sda
  • sata1 = 2nd sata device = sdb
and so on...
SCSI & SATA devices are listed as devices sda, sdb, sdc, sdd, sde, sdf, etc. in the /dev directory. Similarly, partitions on these disks can range from 1 to 16 and are also in the /dev directory.
Now each hard drive has 4 primary partitions (limit of PC x86 architecture). First partition is denoted by number 1. For example:
  • First partition : /dev/hda1
  • Second partition : /dev/hda2
  • Third partition : /dev/hda3
  • Fourth partition : /dev/hda4
  • sata0 device, 1st partition: /dev/sda1
  • sata1 device, 1st partition: /dev/sdb1
And so on.
You can run command fdisk -l (lowercase L) to display a list of partitions:

WARNING! These examples may result in data loss. Use fdisk command with caution as it can manipulate / overwrite your partition table.
