How many amps is a GM alternator?

How many amps is a GM alternator?

Most factory alternators are rated at 65 to 100 amps and are capable of handling your vehicle’s basic necessities, such as headlights, gauges, fuel pumps, A/C, etc.

How many amps does my alternator need?

The amp rating of the alternator is matched to the vehicle’s electrical system. Older vehicles with fewer accessories may only need a 70- or 80-amp alternator, while a newer vehicle with lots of electronics and accessories may need a 120- to 160-amp alternator.

What engine does a 1997 Chevy K1500 have?

The 1997 K1500 had four engine options available. The standard engine had a 4.3-liter V6, produced 200 horsepower at 4,600 rpm and 260 foot-pounds of torque at 2,800 rpm. The smallest of the gasoline V-8 engines, the 5.0 liter, produced 230 horsepower at 4,600 rpm and 285 foot-pounds of torque at 2,800 rpm.

What is the highest voltage alternator?

The highest 12 volt produced by Prestolite Leece-Neville is the J-180 mount 4890JB and Pad Mount 4962PA both of which put out 320 amps. When it comes to 24 volt alternators there is one manufacturers that really stands out – C.E. Niehoff has their 500 Amp C-803D.

Is a 160 amp alternator good?

The high amp alternator will give you more replacement juice if you are running any high amp load appliances. The 160 amp is known to be used on emergency vehicles that are at a standstill and still running lots of 12v power thru said appliances.

What volts should an alternator put out?

A good alternator should put out between **13.5-14.5 volts. Stress test the alternator – Place a load on the alternator by turning on the headlights, the radio and the air conditioning. The voltage should remain high with these circuits on.

How many amps should a 12 volt alternator put out?

The size of an alternator will most likely increase the set amperage, too. High output alternators (often found on larger vehicles) can use between 200 to 350 amps. Smaller cars by comparison, such as a Ford Mustang, will only use about 100 amps with batteries that run at about 12 volts.

How much horsepower does a 1997 5.7 Vortec have?

Is 17 volts too high for alternator?

17V is too high for any 12 V battery. 17 volts is just about max unregulated output on a 12 volt alternator so I would suspect that the voltage regulator is defective or somehow not working correctly. To put things in less dramatic terms.

What should the alternator voltage be?

How do you know if you need a bigger alternator?

amps x volts = watts The total amperage you arrive at will be a ballpark estimate of the maximum power draw of the car and indicates how big of an alternator you need (measured in amps). It’s best to have a professional figure this out; every car and sound system is different.
