However, before I begin, let me catch you up to date, especially important for those of you who aren’t quite up to speed. I’ve been one of the people asking this question, and it’s been long reported to me that the FIP trucks had a wiring harness with a ‘shunt’, which powered the ammeter. However, my findings today show differently. As Dirty Harry once said, “A man’s got to know his limitations” After I explained the basics on Ford’s setup, we set out to find out all we could.

And I should mention, he was very patient with me today, trying to help me understand a lot of the basics I’m going to to my best to try to explain what I learned today here, but since I’m still up up to the ‘apprentice automotive electrician’ level yet, some of what I transcribe here might take a little tweaking in the future for better clarity.

One-Wire Alternators: Are They Better Or Just Easier To Hook up?

The truck shop manual says “If the indicator hand goes beyond the scale on the opposite side of the scale I interpret this to mean reads past full or reads erratically, a wire in the fuel gauge circuit is grounded or the tank unit is defective” The gauge can be checked by: Placing the ignition switch in the off position and connecting the terminals to two series connected 1. Although suppliers of aftermarket sending units claim that their units will work with the stock gauges they will not.

The Pirani gauge is a robust thermal conductivity gauge used for the measurement of the pressures in vacuum systems. It was invented in by Marcello Pirani.. Marcello Stefano Pirani was a German physicist working for Siemens & Halske which was involved in the vacuum lamp industry.

This project started after I realized that I didn’t have the time to wait for the gauges to come back from several sources that I had contacted when I had the gauges out for my own refurbishing project over a year ago. I spoke to Morris and found him to be very customer focused and more concerned that I would get what I wanted done, than several other gauge repair facilities who could only say, “ship the gauges to us and we’ll call you with an estimate.

Names such as Pertronix, Mallory, etc are among the most commonly used on these cars, although Morris can do a variety of conversions. It would be best to specify to Morris what you are currently using for your ignition system and what you MAY plan to use in the future, should any special exceptions need to be made in calibration or wiring. Morris talked to me about the way that he performs the work and exactly what I would be getting for each price that he quoted.

Now he knew up front that my gauges were cosmetically fine, based on the work that I did previously and what is shown here: Gauge Refurbishing The quoting was easy from there and the others had access to the same information, but were “too busy” to look at it as Morris took the time to do. I have no financial interest and received no discount for any work done in lieu of posting favorable comments.

If any of this experience was bad, you all know that I would say that just as clearly as what I’ve said here. Morris does have a new website.

One wire Alternator and working Volt meter

Always disconnect the negative ground cable from the battery before servicing the electrical system. Always, work in a well ventilated area away from any source of open flame or spark. The sending unit with floats is mounted to the top of the fuel tank.

Description o f Operation The Fuel, Oil and Temperature gauges are of the bi-metallic type construction. They are supplied with regulated power from the Instrument Voltage Regulator to improve accuracy. The fuel gauge is connected by a single wire to a float-and-slide-rheostat sending unit in the fuel tank. The temperature gauge is connected by a single wire to a sealed bulb unit mounted in the water jacket of the cylinder head.

The oil pressure gauge is connected by a single wire to a diaphragm-type unit 75 ohm rheostat mounted in an oil gallery of the engine block. The fuel, temperature and oil pressure gauges all appear to be the same mechanism with different faces. Each gauge has 2 terminals. The internal mechanism consists of a coil of “heater wire” wrapped around a bimetallic strip. Each terminal on the gauge is connected to one end of the heater wire and there is no connection to ground.

The more current that flows through the heater wire, the more the bimetallic strip bends and the more the indicator needle moves to the right. Therefore the lower the resistance of the sending unit to ground, the more the gauge will deflect to the right. Due to their construction the gauges are not polarity sensitive and do not need to be grounded.

Hello, I ran a few searches in here and on the net and gave up. I have a set of 3 autometer gauges in pods I will be installing in my 56 tonight. I am not hacking up the dash. I got these from a guy I knew a long time ago. They worked fine in his ranger.

Rahul Aryan 3 months ago Reply hey, i followed your given circuit and made one such but i am using it in bike,then from where to get -ve of ignition coil AlexA 10 months ago Anyone have the PCB designe for this? Can you ask me where you conect the signal capble?? My English is not good, maybe i wrote wrong something. I hope u understand me. LM regulates a potential of 9v and your source is 12v. I have a honda cbr and my tach broke. I googled and found your blog.

I am not educated in electronics but know how to follow instructions. I followed your diagram From Step 1 and the circuit is almost completed. When I wanted to test it in real life I just realised that the ignition coils are mounted inline for each spark plug in my cbr and it is like impossible to get to the -ve terminal.

I wanted to ask, can we modify this circuit in any ways so that it can pick up the signal using induction i.

One-Wire Alternators: Are They Better Or Just Easier To Hook up?

Printer Friendly Well its weird. I also knew my amp gauge wasnt working. So I thought, I will just run a split second of current in each and see what makes the amp gauge move. I was using the “horn” so when I honked it would send a current.

For your electric fencing project, this is absolutely necessary. You just cannot have a good, working electric fence without it. I moved my fenced area for the pigs farther from the house, so needed to extend the wire another 50 feet.

Failure to do so would cause excessive heat in the wiring and switch and create a risk of fire. This is caused by the amount of power being drawn by the high output lights or accessories. A relay works by using a switch to run 12 volts to the relay. The relay acts as an electrical switch that activates and draws power straight from a good fused battery connection and sends it to the lights or accessory.

The power actually going to the switch never gets routed to the lights. Generally you’ll have a larger gauge wire going to the lights than to the switch because the lights pull much greater power. Why do I want to use a relay and do I really need to? Anytime you want to switch a device which draws more current than is provided by an output of a switch or component you’ll need to use a relay.

The coil of an SPDT relay that we most commonly use draws very little current less than milliamps and the amount of current that you can pass through a relay’s common, normally closed, and normally open contacts will handle up to 30 or 40 amps. This allows you to switch devices such as headlights, parking lights, horns, etc. In some cases you may need to switch multiple things at the same time using one output.

The starter cranks a stock flathead engine at rpms. Two brush Ford generators use the shunt type generator design. The field circuit has an internally grounded field. Grounding the field removes all external regulation on the generator and it will go immediately to full charge mode. If the ammeter shows charge when you ground the field, the regulator is at fault.

Pressure measurement is the analysis of an applied force by a fluid (liquid or gas) on a surface. Pressure is typically measured in units of force per unit of surface area. Many techniques have been developed for the measurement of pressure and ments used to measure and display pressure in an integral unit are called pressure gauges or vacuum gauges.

This will noticeably slow a hot starter, but should not cause start problems with a good battery and starter. Frame or Body Connection? In a vehicle, the steel shell is almost always better than a sub-frame or frame connection point. A typical body shell has large stamped areas. These areas are normally welded at multiple points to surrounding panels. Body panels and the body shell have a very large surface area.

The large surface area provides solid electrical connections. Because area is so wide, even a thin panel has a very large cross-sectional area. Sometimes frames are isolated from the body by rubber mounts. My F truck has virtually no cab-to-frame or fender-to-frame electrical bonding, so the wide body shell does not contribute to electrical ground conduction cross section. In the case of a unibody, the frame is an isolated stamped structure.

It is spot welded to the body shell at a few dozen points. The sub frame is probably OK, but it is certainly no better than any other panel.
