An ammeter is always connected in series with the load.

The battery is considered the load in this situation, and the charger is the source. When connected in a normal "battery and charger" arrangement, to install an ammeter, you would remove or disconnect the cable between the + of the battery and + of the charger. Make a connection between the charger + to the ammeter's + terminal. Next, complete the circuit by making a connection between the ammeter's - terminal to the battery's + terminal.

Done.

Note: The ammeter must be capable of showing the maximum amount of charge current - otherwise it could be damaged. If your charger can put out up 50 amps in a "boost" or start mode, you should consider having a meter capable of 125% or better capacity - meaning 50 x 1.25 = 62.5 amps. If charge only and a max charge current of 20 amps, a 25 amp ammeter should do fine.

Good luck!

DO NOT CONNECT IT to both poles + - !!! the amp meter have very small internal Ressistance, it blows of :) Connect it like in the picture how do you hook up amp meter for battery charger - d640b1d6-15c8-40ff-9dc1-eac0eb3b2a1f.png

Assuming the battery is fully charged, the connections from the battery red to starter motor & relay are tight, and black terminal from battery to engine block (or chassis) are tight, and cables &/or terminals are not corroded, and the battery electrolyte levels are not low to expose the battery lead plates, the symptoms you describe sounds like a main fuse panel issue. Some cars have two fuse panels; one beneath the driver or passenger console, another one beneath the hood in engine area. If fuses are OK, then not enough electrons are passing through when you turn the key, meaning something is acting as a resistor to prevent free flow of electrons (loose connections or corroded terminals or cables). When you pop open the caps off the battery, each cell holds 2 volts. If the lead plates are exposed, that cell will hold less than 2 volt. Replenish with distilled water or battery electrolyte (sold at some auto parts store, so call around instead of driving all over town). If you have a battery charger & digital voltage meter, the battery should read 12.6 to 13 volts for fully charge. If below this, touch black probe on voltage meter to negative side of battery, then dip red probe on each of battery cell's electrolyte. Write down the voltage reading of each cell, then hook up the battery charger let charge for half an hour or so until battery shows 12.6 or higher reading after unplugging the charger. With charger unplugged, take digital voltage meter and take 2nd voltage reading of each cell, dipping red probe into electrolyte while black probe touches negative side of battery. Write down voltage reading of each cell. Wait half an hour to 45 minutes, then take a 3rd voltage reading of each cell. If there's a drop in voltage reading on one cell from the 2nd time, this cell is not holding a charge and its draining power from the adjacent cells, resulting in eventually leaving a dead battery after it had been parked over the weekend. Replace the battery. This method of diagnosis to check battery condition is more accurate than a load test. I've seen batteries that will pass a load test, yet battery goes dead after the car (or semi truck or bus) had been parked for 2 or 3 days because the faulty cell had drained power from the adjacent cells next to it. In semi trucks & buses, when the battery goes dead, it continues to drain the power from other batteries that are hooked in parallel or series to other batteries.

Battery drain


drain is hard to find it could be a short or a component is staying on. you need an amp meter and hook it up between your battery negative terminal and the negative battery cable.turn the key off and check how many amp is the drain make sure all the lights and doors are closed, dont crank the car with amp meter on it will burn the meter. take each fuse out at a time which ever fuse drops the amps down by pulling it out is causing the drain. find what that fuse is for. check that component and the wiring on it for any shorts.

1999 Silverado with 139000 miles, turns over very slowly but starts everytime. Battery or starter?? Do not have a meter to check battery


I would suspect the battery more than the starter. But you can check it without a meter. Most auto parts stores will check your battery for free. But if that is to far, how does it start with a battery charger hooked up while starting. If it isn't as slow, then the battery, if it is something else, not necessarily the starter.

Battery in Jeep Grand Cherokee dead this am and less than 1 year old. I have a Everstart 100 battery charger plugged in and on the car. How long does it take to charge the battery. The charger is plugged...


How many amps does this charger put out????
A small trickle charger will take forever to fully recharge a dead battery, you'll need to have a battery charger that can put out enough amps to properly charge a dead battery.To clarify, the chargers sold at Sears, the large square types on wheels are the best for charging dead batteries and they also have an amp meter telling you how much the battery is accepting. After you charge your battery, you should be around 12.5 volts to 12.7 volts. DO NOT OVER CHARGE!!!

Need to charge battery on my chevy venture. Please show me how


Okay... One can not see the negative battery terminal so.... Connect the negative clip from your charger to the chassis and then remove the RED plastic cover in front of the black relay box above the battery OR the plastic cover from the positive battery terminal and connect the positive cable. Make sure you have good connections by watching the meter on your charger. Then plug in the charger and turn it on. Charge time depends on the strength of your charger. I'm going to go hook mine up again because I need to go out for a bit. I don't think I'm going to like changing this battery..... Just thought I'd share..... Good luck.

Meter Explanation


You are correct on all accounts. A high number means you dying battery is sucking more juice from the Schumacker. A low number means the battery is not as thirsty. That's how I always think of how to read the meter on mine. Slow charge is a better, deeper charge. The quick charge will get you going, but you should maybe follow it up using the normal mode - car alternator and prolonged drive time. I never use quick charge, personally.

Batteries won't charge while wired to truck


Hi, seems that your alternator diodes are faulty.
You can check this by disconnecting the radio & switching off all interior lights etc.
Then remove one battery lead.
Then get an amp meter and connect it between the battery & the removed lead.
If you get a reading the alternator is drawing current , hence faulty diodes.
The alternator will still charge the battery when the engine is going but then discharges when stopped.
Also check your batteries with a hydrometer by checking the battery acid in each cell as you could have a dodgey cell in them.
