At the Mountains of Madness

Microwave ovens are probably the most hazardous due to high voltage at high power. There are two areas which have particularly nasty electrical dangers: Major parts of nearly all modern TVs and many computer monitors are directly connected to the AC line – there is no power transformer to provide the essential barrier for safety and to minimize the risk of equipment damage. The flyback generates most of the other voltages used in the unit and provides an isolation barrier so that the signal circuits are not line connected and safer. Since a bridge rectifier is generally used in the power supply, both directions of the polarized plug result in dangerous conditions and an isolation transformer really should be used – to protect you, your test equipment, and the TV, from serious damage. Some TVs do not have any isolation barrier whatsoever – the entire chassis is live. These are particularly nasty.

The Magnetic Coil – Flipper Bushing – solenoid coil sleeve data charts and this page’s Comments have all been moved. Pinball Medic needs coil information on the following: We need part numbers, coil resistance, wire turns and any other pertinent coil design information. This info will appear on a separate coil information page. New “rare” or “hard to find” coil information charts and coil “mug shot” photo pages will also be added.

Jul 25,  · Re: Positive ground tach/dwell meter hook up It sounds like you’ve got a two lead meter. I’m used to three leaded equipment which would require the “red” lead to go to the chassis of a positive ground car, the black lead could go to the ignition switch side of the coil or to the “hot” terminal on the starter solenoid.

EasyDriver V1 – This was the first attempt. Also did not have variable current limit or 5V regulator. EasyDriver V2 – This was the second attempt. I had some boards fabbed at Futurlec without solder mask or silkscreen. The board was twice the size of V1, and routed to dissipate heat much better. The 5V regulator was added. I have since modded the completed boards to add the variable current limit.

EasyDriver V3 – A refined version of V2, with the variable current limit on the board, and switched to components.

Mine and Beachley’s MMC is calculated to be. How to calculate the capacitance of capacitors connected in series: In order to better visualize what a Series Configuration looks like, imagine a string of 10 children hand in hand, where each child’s right hand is held by the left hand of the child to it’s right and so on.

On a positive ground system, the feed from the ignition switch is to connect to the negative marked terminal on the coil. If connected wrong, the coil output will be about 14% less at idle. This percent of reduced coil output increases to as much as 30% as rpm’s increase.

Acoustic telephone ad, The Consolidated Telephone Co. Innocenzo Manzetti first mooted the idea of a “speaking telegraph” or telephone. Use of the “speaking telegraph” and “sound telegraph” monikers would eventually be replaced by the newer, distinct name, “telephone”. Charles Bourseul published an article in the magazine L’Illustration Paris: Reis’ telephone was not limited to musical sounds. Reis also used his telephone to transmit the phrase “Das Pferd frisst keinen Gurkensalat” “The horse does not eat cucumber salad”.

Manzetti illustrated his method for transmitting spoken words on the telegraph wire intend to apply said invention in England on several private telegraph lines”. However telephones would not be demonstrated there until , with a set of telephones from Bell. Antonio Meucci files patent caveat No. Patent Office titled “Sound Telegraph”, describing communication of voice between two people by wire.

A ‘patent caveat’ was not an invention patent award, but only an unverified notice filed by an individual that he or she intends to file a regular patent application in the future. Meucci, after having renewed the caveat for two years does not renew it again, and the caveat lapses. Patent , “Transmitters and Receivers for Electric Telegraphs” is granted. This uses multiple vibrating steel reeds in make-break circuits.

The Ignition timing in each reprogram is developed to maximize performance with specific fuel octane and boost levels. Programs offered are recreational performance tuned with safe AFR values, and can be further custom tuned Richened to accommodate additional boost levels. However, custom fuel tuning with the Powershot Fuel Tuner can be an add-on or additional upgrade that is suggested for higher performance applications such as C5 Monster Wheel Kits.

INSTALLATION INSTRUCTIONS FOR 12 VOLT POSITIVE GROUND APPLICATIONS For volt positive ground systems. Compatible with “points style” coils. Do not use “HEI” type coils. With sleeve lined up on point cam, press down firmly insuring the sleeve is fully seated. Insert both wires through the hole in the distributor housing.

All of the screws are connected through drive shafts and bevel gear boxes, and driven by a single 50 HP electric motor. The units are pit mounted so a great deal of the machinery is below floor level. The machines are used during the fabrication of the heat exchangers. About Bushman Bushman Equipment Inc.

The order also includes two magnet beams. The mill will specialize in manufacturing seamless hot-rolled and seamless cold-drawn steel tubes. The spreader beams were custom-engineered to several different lifting capacities: Length varied from six to 10 meters. Pete Kerrick, president of Bushman, stated that the challenge for his engineers was not only the physical size and capacity of the jib cranes but also the Factory Acceptance Test which was mandated.

Wasted spark with multiple coils It can also support coil per plug in some installs. For wasted spark you require a minimum of single “missing tooth” crank wheel, only engines with an even number of cylinders being supported. You need at least for 4cyl, for 6cyl or for 8cyl. However, the wheel is probably the easiest to obtain.

I used to own some positive-ground cars (’54 Ford, two British sports cars from the ’60s). Actually, at the transformer, the center tap of the secondary coil goes to the earth. The voltage between the outer taps is volts. The voltage between each of the outer taps and the center tap is volts. We could push start a negative.

Changing over from 6v to 12v is one of the easier and cheaper projects to update an old car or truck. The benefits are easier starting and greatly improved headlights, as well as the ability to add 12v accessories. However, before we get into this project, look over your wiring. If your wiring is frayed, split, or cracked, start over.

There is no sense putting all this work into changing over if you’re still going to get shorts and take a chance on burning down the car. It’s easier and cheaper to do it all once than to change over, fight bad wiring, have problems, then have to do it all over a second time Ok, let’s get started First, if you’re wiring and your switches are in good shape, then so are you!


October 22, I purchased a 6 volt replacement coil for my 29 Plymouth. My Plymouth has the original electrical set up – 6 volt positive ground. My question is, which coil terminal should be connected to the distributor points, and which to the battery? I spoke with a technician from Standard Ingintion, and was told that for these old coils, it really does not matter, but it is preferred to hook it up in accordance to the car’s polarity. When I originally purchased the replacement coil, I hooked the coil up with reverse polarity, reasoning that it was probably designed for negative grounded cars.

Hook up the green wire from the distributor to the negative (-) side of the coil. This wire is your life line. Be sure to secure if so it will not break. 4. The positive terminal on the coil is the positive (+) battery side of the coil. this wire should run to your on/off switch. 5.

The problem is that people fit voltmeters wired to the green circuit, which can be a couple of volts lower than the solenoid i. It’s battery voltage which is important, and any volt-drop between there and the green circuit is down to ageing connections, and the best alternator in the world isn’t going to cure them, although it may cover them up.

This was the case in the 5-pin 2-plug 16ACR from 69 to Initially the 3-pin single-plug alternators used machine sensing i. This is a ‘2-wire’ alternator. Clausager states that a new version of the 16ACR with modified regulator and surge protection was provided in March Possibly because of problems with low battery voltage, in the alternators seem to have reverted to battery sensing again Clausager states the 17ACR was fitted from February 73 now with an additional thin brown in the alternator plug wired back to the solenoid as before, and this seems to have remained the case up to and including the 77 model year at least.

The 9 cap is available at your local GM dealer. Ask for AC Delco type RC32 part and a 10 cap is available at most autoparts store under a Stant part number , if they don’t have it, have them order it for you. The lower pressure rated caps are not carried by the store much but they are available. Wright One item that makes the radiator leak is using the wrong Pressure Cap.

Locate the coil wire leads and mark them positive (+) and negative (-). Some vehicles use a plastic wire connector that only fits one way on the coil. Be sure the coil to be hooked up has the same type of connector as the vehicle.

Electric fences offer a more affordable and efficient option to conventional fences. While some people think that making an electric fence charger is hard, it is in fact easy to do. Electric Fence Basics A completed circuit is a prerequisite for electric current flow. This principle also strictly applies in electric fences. Electricity flows through the fence, creating a web-like structure of electrical supply.

Meanwhile, a rod planted onto the ground controls the flow of electricity running from one fence to another. When something touches the fence or the area near the fence, it gets electrified. The electric charger serves as an important part of the electric fence. The following steps provide a step by step guide on electric charger assembly.

Work on the Fence Charger There are pre-arranged chargers or fence chargers that have pre-set features. There are two considerations for choosing the area or the corner: Use Ignition Coil The steel rod should be hammered to the ground. The rod should be near where the pre-arranged charger is.

DIY Ignition Coil Driver

For most people it is only a matter of lack of knowledge, perhaps followed by getting some bad information. How the coil works with points and condenser to create a high voltage spark is covered in another article. This article is a discussion about electrical polarity of the coil and spark plugs. The ignition coil is essentially a low voltage to high voltage transformer with about to 1 ratio of windings and voltage.

The coil case is not grounded, and both primary and secondary windings inside are “floating” or isolated from the case. The only thing the windings have in common is one end connected to the same primary terminal, and it really doesn’t matter much which one.

Feb 16,  · Now you can take a six volt coil and mount it in place of the , hook the wires on the for a positive ground system and everything works fine. So this is my explanation of why a coil is called a positive ground coil as the coil is designed to be hooked up only as a positive ground coil using the cap/armored cable.
