Why do I have voltage but no amps?

Basically, it means your circuit has a flaw or isn’t complete. Improper use of voltage or a bad connection, as well as issues with the panels or solar charge controller, are all possible causes. When a multimeter is connected in parallel, it can overheat and cause a zero-amp reading.

Can a battery have voltage but no current?

If the load is only drawing a small amount of current, then the answer is most likely yes. No one can say for sure, though A battery’s voltage drops over time differently depending on the type. However, in most cases, the voltage will drop rapidly at first before stabilizing and remaining stable for an extended period of time.

Can an alternator put out volts but no amps?

Alternators are capable of producing voltage even when no amps are supplied. Take it to a shop that can measure its output; there is a testing setup designed for this purpose that loads the Alternator.

Can a battery have voltage and still be bad?

Does it really matter what the voltage is on a battery if it is bad? When you intend to use your battery, it will display the actual 12.6 volts and turn itself off. After checking your battery’s voltage, a load test is necessary. Load testing can tell you whether or not your battery is in need of a replacement or not.

Why is my car battery 17 volts?

If the battery output voltage (alternator input) connection between the battery and the alternator is bad, the regulator may be packing up and the alternator is going to max. unregulated output.
