Question on battery caps, second battery and hooking it all up.
Im almost done with hooking everything up. With that being said, I have questions about secondary battery and battery cap. I am trying to go this route to keep from having to buy a high output alternator, which runs $600.00 for my truck. Here is my issue, I do not understand how to install everything.
Here is how I wanted to hook everything up.
12V side: Battery > Fuse > Battery > Capacitor > Fuse > 4 Slot Distro Block > Fuse > Amp
I wanted to know about the ground side though. Is it ok to run the capacitors ground to the ground point on the battery, which then runs to chassis. Most things I am reading is that the cap has to have its own dedicated ground point. Why is this? If it turns out to be true.
Am I going to have to separate my Car PC units from this or is it ok to have it all together?
Final question, with a cap, and second battery, do you think this will kill my need for a HO alternator?
