Which is the standard alternator on a 1500?
The 105amp is the “standard alternator” I have that in my 2000 1500. The 135 or 145 amp was for heavy duty applications like the snow plow prep package…… Funny thing now is the standard alternator on a 1500 now is the 145 or a 165 and the heavy duty is bigger.
What kind of alternator does a GM truck use?
Hi folks some more light on the GM alternator situation since it’s kinda confusing. For a long time The General has used both small-frame and large-frame alternators depending on the truck, with diesels and plow trucks getting the large-frame and most of the others getting the small frame.
Do you need a second battery for a truck alternator?
1. Second battery only increases power when starting and helps add capacity to running stuff when the truck is off, for when the truck is on the alternator does all the work 2. you might want to look at a bigger than factory spec alternator if you are running so much stuff.
What are the extra pins on an alternator?
The extra pins were an unrectified stator output used as a tachometer drive in some applications, and a field terminal used for diagnosing alternator problems, and were dropped as a cost-reducing move. I don’t think either of these was ever used for anything in a truck application.

Can you have too much amperage in an alternator?
You can never have too much amperage when it comes to alternators; therefore, you never have to worry about choosing an alternator with too high of a rated output. Here’s why:
How is an ammeter connected to an alternator?
Simply connect the ammeter in series with the battery’s ground terminal (with the engine turned off), switch each electrical component on and off, and note their amperage draws. Add up the total electrical draw and compare with your alternator’s rated output. The output should be 50 percent greater than the draw.
Which is alternator do I have in my Silverado Sierra GMC Truck?
Thanks but my problem is that the truck doesn’t have its original engine. The first motor was also a 4.3 and hopefully the same alternator, but to be sure is there anyway I can tell on the alternator what its amperage is? Re: Which alternator do I have?

How many amps does a Duramax alternator have?
A typical alternator has around 100-125 amps of capacity in a heavy duty situation. This rating is usually only good at 1500 RPMs or more. At idle you may only have 60-80 amps available. For most of us that wouldn’t be a problem because we don’t spend much time at base idle with everything turned on.
What kind of alternator for Buick Grand National?
The car has aftermarket dual 11″ Spal radiator fans drawing approximately 38amps. It’s obvious the stock alternator can not produce enough power to keep the voltage in the 14v range. We installed a PowerBastards.com 240AMP Buick Grand National Turbo High Ouput Alternator to cure the problem. Watch the video .
