Alternator Upgrade
#22
how much did it cost for the parts to convert?
also the stock alt is only 60 amp. do they only have the one alt model. because my truck has power everything and rear heat and all that good stuff you think logically toyota would put a bigger alt in my truck than say a base model that has power nothing.

Yes, but "power everything" does not involve a lot of electrical power. Power steering is powered by the engine and power steering pump. Power brakes are powered by the engine vacuum. Rear heat is from engine coolant and only the blower for the rear heater takes a few amps of electrical power. Power windows use a little power but only rarely.

also my truck runs at 13 volts is this normal for these alts i know all my other trucks have been over 14V

I think that somebody all ready posted the link with the "how too" and that's the one I used, pretty simple. Hardest part is getting the pulley off to seperate the rotor from the case. Just have a pulley puller handy.

Important thing to remember when y'all are comparing output amps, is if they are specifying hot amps or cold amps.
Usually a pretty significant difference between the two.
If you're looking at one and it's spec is, say, 60 amps, that may actually be putting out more power than one rated, say, at 90 amps, if the 60 amp was spec'd as hot amps and the 90 amp one is spec'd as cold amps.
Very important, always, to find out what they are spec'ing to make like comparisons.

is it possible to test the alt with a volt meter, or do you really need to take it in to a shop for a bench test?
I'd like to do the stock rebuild, but wanted to test it first to see what kind of power I'm getting. Then test again to see the dif.
Definitely tired of all the lights dimming when I come to a stop.

You would need to do a load test with a high power resistor bank, not something the average person would have at home. You could install an ammeter shunt in the power line from the alternator and see what it is putting out under various conditions. However, you may not see the full output of the alternator because it'll only put out the current needed by the vehicle's electrical system load.
