Ford Ammeter Gauges: Do They Work?

It was toast but so was the alternator. One glance at the ammeter, while driving, is enough to assess the health of the charging system. In other words, it is a battery fed circuit that is totally live at all times, and in many instances is completely unfused. Cost is definitely a factor ad well as safety. Then you can continue the install of your new gauges. After you have connected your red 14-gauge wire to your battery post, take the other end and connect it to your ammeter terminal. Power just flows through it so removing the gauge severed that electrical connection to the rest of your car, and is probably why the key doesn't work I know connecting a red and a black together doesn't seem right, but in the case of those 2 wires it has to be when the amp meter is removed.

What you really want to know, is if the battery is charging. People love to blame the amp meter because it is in that wire but in reality they are not the cause. By design, if you ever do, chances are there's something wrong! When Ford started installing Alternator Gauges in its cars around 1964, most were designed so that all of the power in the electrical system passed through the gauge. Current discharge is indicative — and there are times when you need to know what current is being drawn. You could find a range of news, ideas, articles, anywhere in the world in only seconds. This is going to be the volt gauge.

When we do this, it changes the path of the charge. Most of the radars I worked on built in the late 50's were designed to measure amps indirectly. Ideally, this will be 9 volts during engine starting, and 14 volts with the engine running with anywhere between 13 and 15 being acceptable. Connect your tester to the ground, and start probing for a Switched power wire that only has power when you turn the ignition key to the on position. When you turn on the lights and accessories, the voltage regulator senses the lower voltage and kicks in the alternator. If the melting continued past the ga. Being the wiring guy at an auto dealership, I've seen a few burn jobs.

Usually, the brown wire is the accessory wire and the green or blue wire will be the main power to the ignition. I've installed ammeters in my cars before and never had a problem with one. The displays are bright and readable though naturally the green ammeters appear brighter than and sort of wash out the red voltmeters. This heavy capacity circuit is more dangerous in a accident, because it is seldom fused on both the alternator and battery end of the circuit. Bought an ammeter and shunt from China with no instructions how to wire it? Plus today they have a lot of maxi-fuses that can handle what some of the larger alternators produce. Play it safe, and use all-new 10 gauge wire when installing either a voltmeter or an ammeter.

But keep in mind that the amp meter is monitoring net current in or out of the battery. If you switch on all lights and accessories with the engine off you will see a large discharge, perhaps -20 amps. The reason cars are burning up now, is that the generators that put out 20 or 30 amps at full charge, have been replaced with alternators that have an output of over 100 amps.

If you want to monitor only the health and operation of the generator, the amp meter can be connected in series with the dynamo output wire. I am truly disappointed in the vendor for making false claims. If you wire it as it was originally, you will create a dead short. Step 14: Run a wire from the gauge to a grounding point under the dash. When properly wired in series with an electrical load the amp meter will monitor the current flowing in the circuit. As such, this large unfused hookup wire represents a personal safety risk fire or burn hazard , so you need to be very careful to protect the wire from damage, and proper bulkhead grommets are first order of the day.

The amp meter may show +1 to +3 amps during the day when the headlights are off, and maybe everything seems okay. If you're replacing an old ammeter with a voltmeter, you'll need to wire it a bit differently. If the vehicle electrical load is high all lights and accessories on or the battery is significantly discharged, the dynamo output will be high perhaps 20 amps. Step 3 — Disconnect It is very important that you take the time to disconnect your battery before you do anything. . Your parking brake should be a pedal or a hand brake. Positive side of volt gauge goes to hot at switch on.

The meters stay on down to about 3. While this can tell you how much electrical power the car is consuming, it will tell you nothing about the state of the battery or the generator. Also make sure the connection at the printed circuit on the gauge cluster itself is clean and tight. So from then on I've added a fusible link in the 10 ga. If the needle is centered or slightly right of center, all is well. If the alternator is not working or unable to keep up, the electricity flows from the battery and shows a negative reading -. Step 5: Decide where you want to install the gauge.

I needed one rated at least 180 or 200 volts. The meter was accurate out of the box at 13. A shunt wire in the circuit allowed only a small amount of electrical power to flow through the gauge itself, which meant the needle didn't move very much. That is to say, run dedicated ground wires to every component that might normally just be grounded to the body or chassis. You need only drive until that charging current comes back down into the normal range. You should gather a pair of safety goggles, gloves that permit hand dexterity, wire strippers, a red 14-gauge wire that comes equipped with eyelet terminals, a socket wrench, and a screwdriver.
