Cool thank you all for your input for now i have to replace my rusted out gas tank. The top has a hole in it from the salt on the roads in Maine so after that ill be looking for a alt and get it all mounted up i will most likely post some picks because i don't hear of many 4.3L with a dual alt setup. As for my bat it's old on it's last year of use judge by the date and i plane to get a dual purpose bat with top and side mounts.

Is the MLA module required for two alternators to function normally? I checked my alternator it is a simple main power out and a one small wire i assume it's for the computer to manage power output.

Hello I am new here and i have a need for more power. I own a 99 4.3L v6 s10 I have a small System and my stock setup handles it just fine. But i recently added 4 off road lights on a light bar and extra brakes lights and back up lights. When truck is at 1k rpm or better voltage does not drop. But while sitting at a stop light voltages drops dramatically without the lights on. The new addition of brakes lights seems to pull alot of power even though i set them up just to be like lights on a trailer. When on the brakes and with blinkers on the voltage will pulse up and down with them. Every thing is wired properly checked several times. Well now to my question it seems that i need more power at low idle will a 2 alt setup help me out? I never run the lights with out the truck running so im hoping that the 2 alts will help them plenty. What im wondering is the Amps the stock alt can produce and if 2 stock ones would be the cheapest way. I can get a stock alt for around 50 easy. And the mounting i can deal with i can machine the brackets. Ive seen some one mount the alt right beside the other one just infront of the throttle body.
