How many amps does the alternator produce?

Amperage data is not supplied by the manufacturer, however it follows the OEM specification.

This will greatly depend on the alternator's output of your Econoline van. We recommend that you consult with the owner's manual to find the actual output of the van's alternator. For example, if your alternator's output is 100 amps, then the wattage output is about 1,200 watts (watts = amps x 12 volts). Please note that the electricity produced by the alternator is mostly allocated for the van's usage.

The alternator has an internal voltage regulator that controls the charging process according to the needs of your battery and your bike's electrical system. It will not overcharge the battery.

dc. volt range 200 volt. It should read between 12 and 14 volts. If it reads less than 12 volts with the engine running, you have a faulty alternator.

I purchased two of these and they both burned out in just a few days at the rated voltage. So I don't have them any more. I'd try to get a tech sheet and find the resistance of the control circuit and divide the applied voltage by it (If you have a 12 volt battery and the resistance is 1000 ohms you would get 0.012 amps, or 12mA, though you should check the voltage of your battery with a meter (Measuring th evoltage of the battery will get the alternator voltage too) it's probably closer to 14).

15 amps, and it will pull the full 15 amps when starting up the compressor. After starting, it evens out below the 15.

When engine is running, the alternator in your car charges the car battery, so the voltage in your car circuit is more than standard 12V (it will be somewhere between 13-14.4V). The compressor is designed to run from 12V and this is the voltage when the engine is stopped. Keep the ignition key in the position which powers all accessories but do not start the engine.

these are great for 12 volts DC.the relays will handle 14-18 volts DC. most vehicles have a charging rate of 13.8 to 14.2DC. the current coming out of your cigarette lighter/ charging ports is 13.8 to 14.2 volts. the alternator needs to put out that much current to keep your cars battery charged while operating all headlights, heater/ac blowers, defoggers etc. personally, I would not run more than 20 amps thru these. I do use these for lower amp projects but use better bosch brand relays for higher amp projects. look for relays sold by bosch or hella if you want a heavy duty relay. you will notice the big price difference when you look at the brand name products. there is a reason because of quality. these are great for 12 volts DC.the relays will handle 14-18 volts DC. most vehicles have a charging rate of 13.8 to 14.2DC. the current coming out of your cigarette lighter/ charging ports is 13.8 to 14.2 volts. the alternator needs to put out that much current to keep your cars battery charged while operating all headlights, heater/ac blowers, defoggers etc. personally, I would not run more than 20 amps thru these.

As previous answer said it's about currents. Alternating Current (AC) produces a magnetic field that this device detects. Vehicles only produce alternating current in the alternator BUT AC is immediately converted to Direct Current (DC). The only way to test for current in a vehicle is to use a standard multimeter.

Mine was 30 amps. Used it for a trans brake and a line lock solenoid On my race car. Keep in mind use a in line fuse I use a 25 amp fuse to be safe.

Hooked it up to the car. Used between 5.5 and 6 amps. With the car on it went up to 7 amps. I have an "average" car battery and alternator. Other setups will cause different amps. At 7 amps you may note that it is about 75 watts.

around 40-50 amps, when it runs for a long time it takes a little more because it heats up. I have been using it daily since I got it and only blew out 1 of the 40 Amp fuses just recently. This thing needs a lot of power and will kill batteries if you let it.

No. It takes 110 volts AC. Your car provides 12 volts DC. A 1500 watt inverter would draw about 150 amps from your car battery which is more than most alternators can provide except a fuse would probably blow first. 12 volt car heaters are available.

I have a set of 10" fans on my 36 chev. They both draw about 12 amps each. So a single is 12 amps dual should aprox, 25 amps .at 14 volts .measured during alternator charging.

The unit I got did not have "HD" in the part number, so I assume it's good for 100 amps. I needed one for a 160 amp alternator.

No, the other answers are wrong. It does not test not alternator amperage. For that, you would need an ammeter. Use a DC clamp ammeter so you won't have to break the circuit. What the BA7 does check is the alternator voltage. You can also do that with any accurate voltmeter. The proper alternator voltage when the car is running is 13.5v to 14.2v across the battery.

I have one of this in a silverado pick up and it can handle the alternator output current.
