    Troubleshooting '68 Mustang: Hot Wiring and Checking Ignition System

    Averagesupernova “You should never ever ever ever ever have power on one side of an ammeter and not on the other.” That is not what I said! I said it seeks ground through the yellow wire when the engine is not running. However, there are several paths involved, including the key being on for...

    Troubleshooting '68 Mustang: Hot Wiring and Checking Ignition System

    Actually you should only get power to one terminal of the gauge at a time. With the engine not running the power should be on the black wire (with reference to ground). The yellow wire finds ground eventually through the ignition switch and some accessory, so I think it is normal to only get...

    Troubleshooting '68 Mustang: Hot Wiring and Checking Ignition System

    According to the wiring diagram from themustangshop that I posted earlier, there is a yellow and a red wire going to the ammeter. Both of these wires go to the same plug (different terminals) then both end up near the battery side of the starter solenoid. They do not connect to any other wires...

    Troubleshooting '68 Mustang: Hot Wiring and Checking Ignition System

    “My car is a 4-speed manual shift and doesn't have a neutral safety switch (automatics only).” That does not mean that the switch is not there. On manuals the neutral safety switch has to be jumped permanently. There is a Red-Blue wire running from the S (start) terminal of your ignition...

    Troubleshooting '68 Mustang: Hot Wiring and Checking Ignition System

    Where do I go from here guys?...What do I inspect next?... Do a Voltage Drop Test. It is by far the best test for a starter circuit.: http://www.sacskyranch.com/voltage.htm http://www.youtube.com/watch?v=XhRPLgH6uZg&feature=related...

    Troubleshooting '68 Mustang: Hot Wiring and Checking Ignition System

    When you shorted the wires together you likely melted the wire insulation or burned some pins in a connector. Regardless it appears that you are getting a circuit from the wire to the battery side of ampere gauge and its finding ground through the oil pressure-sending unit. This is giving a...

    Any ideas on what material this is?

    Seal material depends on what fluid the seal is keeping in or out. The hardness is usually given a Durometer number. The seal shown is generically called a Garlock seal, but there are many manufactures of this type of seal. The way you can get material is to get the part number off the seal...

    Undergrad Relative humidity at negative temperature

    “as we know at zero degree temp. water condense to form ice.” Water melts at zero degrees C; however, it can be in a liquid form at temperatures as low as –40 degrees. See super cooling: http://en.wikipedia.org/wiki/Supercooling As for relative humidity: it is defined as the ratio of...

    Can We Artificially Create Clouds?

    Here’s one way weather can be modified. It doesn’t create clouds, because they are already there, but the precipitation is in form of rain, instead of hail. http://www.wingsmagazine.com/content/view/1555/38/

    Undergrad Density altitude and applied ballistics

    I don’t know what chart you are looking at, but density altitude depends on the air pressure, temperature and humidity. Decreased air pressure, increased temperatures and increased moisture reduce the density of the air. You can usually ignore moisture, There are rules of thumb to determine...

    Convert Precise Readings to Accurate Values Without Calibration

    Accuracy and precision are two different things. A measurement system can be accurate but not precise, precise but not accurate, neither, or both. See Accuracy versus precision; the target analogy here: http://en.wikipedia.org/wiki/Accuracy_and_precision
