Grounds shouldn't be an issue. Lol.

Called in 2 days ago and was asked to leave a number and email address and I did so. Haven't heard anything yet.

Its a mechman 240 internally regulated. Dont have a voltage meter on the 12v side yet but the gauge in the instrument cluster seems to move a bunch.

Pulsating fluctuates with rpm

Alt on the left is the one in question.

I have a 240a pcm regulated on the 12v side of my truck. Every once in a while my lights will start to "pulsate" with rpm. I can tap on the alternator and it will stop, but it will start back after a good while. Could this be the brushes or regulator? Or something else? All wires are upgraded going to the alt and the plug is in tight.

Going to be getting a new belt soon and possibly new tensioner. Working on the inside first.

The alternator with the finned rear cover is a externally regulated 340 amp.. As for the other alternator with the black rear cover It could either be a 240 or a 270 amp G series So they are in fact mechman?

And the plan is switching to an ampere audio 7.5k. Would that quantity of batts still be alright? Will add more as I go along.

Ok so if I was to do say 4-6 of the d1600 or the Xp1000 it would out perform the 8 kinetiks?

Which ones would be best? Xp1000 or d1600?

Truck has a mechman 340a alt dedicated to the 16v side.

Right now im running 8 kinetik hc16v batteries. Im wanting to switch to xs 16v batts. Im running a NS1 @.5 on 16v now. How many and which 16v batts would be good for my setup?

Any help?
