They look good also in red!
Anyhow is very simple and easy to figure out. There are six wires coming out the black box I could then gain access to the heart of the potentiometer, the trimmer. They are OMP racing seat with 4 point harness. Can you please post info on the donor new part Datqsheet them in the car since 8 years.
Mar 21, 2, Gdy29 Jersey Full Name: Will try as you suggested, however, it will take some time since, as said, the entire dash and central console are out of the car at present. Dennis Try this link http: Any pics on this: The total measured impedence between the left and ratasheet right pins of the working half gave me Kohm. They are getting covered in black Connolly leather to match the rest of the interior as we speak.
Share This Page Tweet. A small current bdy9 the base is amplified to produce a large collector and emitter current. Wonder is something went bad there.

Steve indeed my TR is an 87 model so quite an early one. It is impossible to regulate the fan speed. Each half is actully a stand alone unit. Just for my piece of mind, is it normal that sped control knob has a switch integrated?
Jul 25, 11, Amersfoort, Holland. Collector – Emitter Voltage Vceo. What they all do have in common is that all three are based on the “common emitter” principle for the variable speed operation — i. Have, in the meantime, removed the dash to fix the usual leather shrink, and removed the potentiometer.
Aug 16, Sydney Full Name: ChairmanMay 19, The second pic below shows the trimmer removed from the original unit with no impedence at all and the third pic the trimmer removed from the new unit. Aug 25, Switzerland Full Name: After having redone the front dash cover usual leather issuehave reinstalled the all dash and center console and the fun control unit works just fine. I found 2NG or equivalent will work well. Because the controlled output power can be higher than the controlling input power, a transistor can amplify a signal.
I replace mine with 2n E made by On semiconductor also says Mexico Bm The hard part is finding a company that will sell you only one. At this point the blower work basically at full speed. Good day since last Summer, and only of a sudden, the fan blower speed control in the center consolle of my TR just work on an on and off basis.
Also ask for a heat sink for it that fits over the top.

A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. Tks Kerry and Steve. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Visually they look very similar, althought the new one had no switch and was a little bit shorter. If you want to chat about how to change it out, Pm me and will exchange phone s Dennis.
Unfortunately, there are two different TR AC units and three different TR speed controls and the wiring is a little different — and your report of having 6 wires on the fan speed control unit makes me think that you have the early type maybe with the built-in 1A fuse. Noticed that the potentiometer used is welded into a small board circuit with few components.
These two kinds of charge carriers are characteristic of the two kinds of doped semiconductor material. If you have no current in this wire, that is a bad sign for the speed control unit — but also make sure that you have checked that the small 1A fuse if so equipped on the fan speed control unit is OK.
The poti is a double one with switch.

I put one on mine and I have had no trouble for 2 yrs here in AZ. You can access this by carefully sliding a thin piece of plastic under the vent to push two tabs that release the vent- it then pulls out. If 1 is OK, connect an ammeter into the wire going to the base terminal.
Obviously the old transistor was, in fact, good. Jan 11, 17, Texas Full Name: What I would do is: The shape is not oct the same but, with a bit of work, the new trimmer can be fit in the old body. Now the bad news, whilst it seems difficult enough to get a double one with switch,there is no indication of the impedence on the Poti nor if it is linear or logaritmic type
