Ok, my oem alt is taking a dive, I have a ho alt to replace it with. My question is; Do I have to add a second battery when I install my ho alt? If I don't install second battery, will the ho alt damage anything in my electricals? Thanx in advance.

 
You don't have to add a second battery if its not needed. But chances are if you are needing to add a HO alternator than you probably need an extra battery. The alternator wont damage anything without adding additional batteries. Alternators regulate there amperage output. It will only put out high amperage if needed

 
I have to add the ho alt because the oem is pooting on me, what's up jim? Thanx for the responses guys.
Not much man. If you have the stock battery you might wanna get a agm but that depends in your batts age to Do fix it if it ain't broke

 
Naw I have a red top under the hood, so I should ok, right? I do have a small xs agm I got from mylows just in case. Again, thanx guys, enjoy your judgeship this wkend jim. If we need your help, I will a reachout. Y'all have fun, ya hear!!

 
My usual order of electrical upgrades is:

-Big3

-Make sure you have sufficient size wire and solid ground to amp

-Deep cycle battery to replace stock battery

-Add 2nd same type deep cycle battery in rear
