The voltage regulator has the job of making the voltage 'constant'. In most modern vehicles the regulator is located in the alternator, in older models the regulator is located separate. If your voltage is jumping around a lot then you either have a problem with the battery (batteries stabilize the voltage also)or the charging system (and probably the voltage regulator)
What else can I help you with?
Why does your car fail to produce 12 volt constant?
Your car should produce about 14.4 volts from the alternator when the engine is running. If it does not produce anything over 12 volts, your alternator is not charging and you need to get it repaired or replaced.
How do i test a 24 volt alternator?
with a voltmeter
You put new alternator and volt regulator in 1987 f600 370 engine and volt meter says 12.8 with engine off and on?
Check fuseable link on alternator Check fuseable link on alternator
How do you get a 12 volt pm alternator to give you 110 volt ac?
Purchase a power inverter.
110 volt ac car alternator?
I hope not, it'll cook the 12 volt DC system.
What is the procedure for checking alternator output current?
Use a digital volt meter set to the 20 volt DC scale. A good alternator will output 13.5 to 15.5 volts.
How much volt battery can be charged by an alternator?
If we are talking about cars only: the system that charges the 500 volt battery in a Hybrid is a Alternator. So in theory there is no limit. Most cars are "12 volt" (common usage, incorrect) systems.
How much volt alternator should produce?
13.5-14.4
Is a car 12 volt battery ac or dc?
The CURRENT is actually AC coming Directly from the Alternator. A voltage regulator/converter then takes it to DC. For all practical purposes, a typical automobile operates on 12Vdc. The Alternator actutally puts out about 14 Volts to allow for constant charging of the battery.
Can you charge a 12 volt battery with a 14 volt alternator?
Yes. It is done all the time in automotive electrical systems. The alternator, which creates AC, has its current rectified using diodes.
How do you test an alternator with a volt tester?
Check the voltage with a volt meter at the battery with the engine running at idle. You should read 13.5 to 15.5 volts. Any less and the alternator is not charging properly.
What Voltage is expected for a 1998 dodge ram?
== == It is a 12 volt system. The alternator should put out 13.5 to 14.5 volts with the engine running.== == It is a 12 volt system. The alternator should put out 13.5 to 14.5 volts with the engine running.
