Question about Sharp EL-738 Scientific Calculator

1 Answer

The calculator is intermittent: Most of the time

The calculator is intermittent: Most of the time the display is erratic (half of the LCD display turns on and it is imposible to even enter a number on the key pad). Sometimes, with no batteries in the calculator and with a strong light source, it works normally for a short time then it tilts again (erratic display).

Not knowing what to do, I tried anything that could possibly help:

I installed fresh batteries and I pushed the reset button on the back of the calculator (Sharp EL-546L) and finally, it work all right after more than 5 years I own the calculator and where it did work correctly for 5 minutes. I tried the reset button in the past (long time ago) and it didn't work. This time it worked because, maybe, I've used fresh batteries.

Code 15 on 1988 ram 150 without vehicle speed sensor


Code 15 relates to a failure in the vehicle speed sensor circuit. The job of the vehicle speed sensor is to inform the computer about the speed of the vehicle so the computer can calculate engine load and prepare the engine idle speed control system while the vehicle is decelerating. On deceleration, the idle speed control system will allow additional air flow into the engine as the vehicle rolls to a stop. Usually code 15 will be accompanied by erratic speedometer readings (or no reading), erratic AT gear shifting, TCC lockup clutch instability, and intermittent or complete failure of the cruise control.

I just filled up my tank and now the light is on and the tank shows empty?


{: ) Your fuel level sensor could be intermittently reading high resistance and may need replacement. An intermittent reading can happen at any level (say 1/4, 1/2, 3/4) and will suddenly give you an empty reading and fuel light, sometimes an SES light may follow. At any rate, this kind of symptoms still recommends replacement of the fuel level sensor.
You can observe it by yourself. Does it read normal on lets say half full but will read empty when you can calculate that you still have 1/4 remaining on your tank. In your case you've just filled it full, and it's no different once the fuel level sensor start getting erratic readings.
Although it may take time, you can wait until the fuel level stabilizes to a certain lower level where you think your gauge was reading normally before. You can also do some stop and go, forward and reverse, to slosh the level arm to a a more readable position. Check if you can get clearer results out of this trick.
A scan tool is a better tool to determine quickly the condition of the sensor and may tell also if there are other codes that is related to your problem.

I'm using a TI-83 Plus calculator. Halfway through my screen there is a straight line preventing me from using the top half of the screen. No matter what I do I can only use the bottom half. Is there...


You probably have your calculator set to display the graph on the home screen. Try pressing MODE and going to the last option, then changing it from "Horiz" to "Full". "Horiz" means it is displaying the graph (probably without axes since your screen is otherwise blank) on half the screen.
