  • Handy Plug-In Line Voltage Tester

    Here is a handy line voltage tester for only $4.
    We know that line loss is critical to the life of electric motors, and a few years ago I lost two air compressor motors due to low voltage.
    The loss was a corroded connection where the lines connected to the house, and the power company fixed it, but too late for my motors.

    I lost a Central AC compressor when one leg of the 220 to my house dropped out at the pole. Luckily my insurance covered the replacement of it.
    Campgrounds are famous for having reversed polarity and floating neutrals. This could be a handy gadget to ID those issues also I would think.
    I wired our camper with an American Made Progressive Electrical Monitoring System that also alarms and trips out if the frequency strays below 59Hz or above 61Hz. Not cheap though - that was about $400 as I recall...
    Good find!

          You better switch off the power & see if your DYNAMO still runs. When is it due for an OIL CHANGE?---Detergent or Non-Detergent? What Weight & Brand? Where's that Horse? Can't get Emojis from a Comment Window-----

          I use one of those on my generator when the power goes out. It is an easy and cheap way to ensure the output is correct.

            Another Gadget for your Model A
            by Tom Wesenberg
            Well, not to be outdone by Pat with his built in mirror compass in his modern Ford, I thought I'd buy a digital compass for my car. This is a nice unit that gives inside and outside temp, date, day, time, alarm clock, and digital compass. It's listed as 12 volts, but I just tested it on my regulated power supply, and it works fine down to 4 volts, so it's going to work fine in your Model A. On 12...

            A Variable Power Supply and Battery Charger
            by Tom Wesenberg
            This is a very handy tool to own. It's a variable power supply and battery charger with 2 ranges, 0-8 volts, and 0-16 volts. I bought mine at the local surplus store, thinking it was a working unit. It turned out it wasn't and it only put out 5 volts, which dropped to 3 volts after a couple minutes. I did some serious cleaning, and got mine to look as nice as this one on ebay. I took the case off...

            A Slight Delay in Making New Voltage Regulators
            by Tom Wesenberg
            When I started making voltage regulators years ago, I bought my transistors from the local electronics surplus store. I bought all 15 Motorola transistors that they had, and they worked fine. I then found a guy on ebay that had a box of 200 ON brand, so I bought his, and they worked fine. Now I'm down to just a few left, and I couldn't find the ones I wanted from an American supplier, so I ordered...

            can the 6V tester be used for twelve volt? What changes would be needed to test 12V coils?...

            Electricity 101
            by Tom Wesenberg
            When making electrical checks you can be measuring voltage or amperage. Voltage is the pressure behind the electron flow. Think of a high pressure hose squirting water on the lawn. It might have 40 pounds of line pressure, but not a lot of flow. Amperage is the amount of flow. Think of a river which flows hundreds of gallons of water per second. It doesn't have much pressure, as you can hold the open...

            31 Vacuum line
            by JohnB15632
            The vacuum line that originally cam with my Model A is plugged solid.
            Any ideas how I can get this tube unplugged?
            Would it be better to try to manufacture/bend a new vacuum line?

            Model A Charging Socket and Fan
            by Tom Wesenberg
            Cell phones and GPS work fine on your stock 6 volt positive ground vehicles. Just make sure you connect the center contact of the socket to the positive ground. I bought some of the black insulated sockets shown on ebay for 99 cents each. The blue USB adaptor was a dollar at Dollar Tree. The USB and multi socket adaptor was less than 3 dollars, and will work on 6 or 12 volts, as the USB ports are...

            Proof of the BIG Bang Theory or Air Compressor Explosion
            by Tom Wesenberg
            If you don't drain your tank, there will be a BIG BANG.
            I posted this several years ago on another site, but there are several new members here. I was in my basement working on the computor when I heard and felt an explosion. I went outside to see what happened, and found my neighbor standing in his driveway looking like he was in a state of shock. He was using his air compressor to blow the...

            Power Outlets for GPS and Phone
            by Tom Wesenberg
            Here's a link to the outlet I use for powering my GPS and phone. Just cut the plug off and connect the positive wire to ground, and the negative wire to a convenient terminal, such as the rear of the ammeter, or to the starter switch terminal. Leave an inch or two of wire on the plug, and you can use it for some project like a jumper cable to keep a spare battery charged while you drive.
