Alternator Question

[Kaoseighty9]

i searched up the converter for amp's to watt's
and I'm pretty sure i have a 70 or 75 Ohm's alternator
but what I'm getting as a result is

P = I 2 x R ?? this right?

power = amps(squared) x resistors
if so that's like
2940 = 70² x 0.6 <-- I'm pretty sure it has 0.6 not 100%

if some one could correct me in any way please do
this is what i researched and i don't get electricity very
well.

converters , or inverters?
ahhh, conversion equations.

Power (dc) = I x A. or I squared x R.
alternators are rated in amps. ( volts is a give right. 12.5 to 14.7)

if you have a 70 amp alternator , it can output 14.7v x 70a = 1029 watts ( or 1k watts.)
it varies by RPM and the alternator mfg has charts to demonstrate the performance.

are you trying to do an energy budget , just ask how to do.
?

add up all the loads , in amps.
that is what you need.

at a little more for hot days.

okay thnx because if thats to im at like dead end line
because i have i think lights are like 830watt's? + 300watt amp?
thats pushing it al together haha

[jtgh]

no problem.
you have 4 x130 plus 2 x 100 . so that that's 520 w + 200 or 720 watts added.
divide that by 14v get 51 amps. you need ,

FSM says stock alt. is 55 amps.
so you have maybe half remaining on the stock. ( shooting from hip)
you have 25(factory) amps to play with , you need 51 to run lights.
so you need 25 amps extra over stock.
i round your lights down to 50. ( so you need 25 more amps)
55 stock+25 need = 80amps. so you at least need a 80amp alternator. total.

dont forget stock, has lots of overhead capacity but cant do 51 amp extra.
if you have huge power audio amp that can play in.

no clue but thats what i have installed this minute and for the past say month
and they both work together but i read up that stock 98 kick sport has 70 is that wrong?

[jtgh]

varies by country ,and year. ( i quoted FSM from USA E03 market KICK)
i cant search all 93 markets to find max amps. all kicks. no can do.

only way to find reality is pull alternator get OEM name and part number.?
Mitsubishi? then p/n , then look it up at Mitsu. dot com. (catalogs)

someone could have changed it out.

cheers.

okay well thnx i know a friend take his alternator to a shop close to where i work and
they re build it so its stronger im going to have to do that or add another battery if i want a 10K winch ahha well thnx for your help

[jtgh]

that's correct any good electric shop can up the alternator amps.
most.
unless , maxed out now.

winch, another power eating monster.

Just Buy A Deep Cycle Batt Big 3 Upgrade New Alt

get a chevy alt kit. it has the bracket to bolt up and you can get it with a 105 amp alt or get your own and put a 200 amp one in. i think there 45$ for the bracket and 120 for alt, separate.
