the old 76
For those of you that might have been keeping up, Its been awhile since I've been here. Like the changes that have been made so far.
The real reason for the post.
I GOT THE 76 4X4 on the road. It's ugly as hell but I don't care. Ain't got a bed yet. Had some people contact me about that and preciate it. I'll be posting pics shortly to let you know just how ugly it is.
Also, can anybody tell me how to add a second battery to this truck
thanks yall

Congrats on the truck running, I know exactly what that's like and it's a great feeling. Mine took 4 years, and now I'm working on the looks.
Dual batteries are great, there are several options. I've seen stock relays used with an inside 3 position switch:
a. primary battery
b. both batteries
c. secondary battery
I think that's how it goes.
the other option is a $29 batt isolator from the local parts store.
The other option is the expensive $100+ for the Painless solution. I'm not sure of the difference, could just be quality.
I like the idea of a simple switch that selects batteries, easy to fix, cheap and all you have to do is throw a switch if the battery dies, but you'd have to throw it from time to time to keep it charged. I think the batt isolators do this automatically.

I have a 75 F250 4X4 with dual batteries. I went the route of using a marine switch that will give you Batt #1/Batt #2/Both/Off. I wired it with welding cable. The switch will fit just to the left of the driver's seat base. One nice thing about having the ability to shut off the juice easily is that when something goes wrong you can just turn off the power fast. I have a snowplow on mine and occasionally a solenoid hangs up. I just shut off the batteries (turn the engine off first) and fix the problem. It also makes a good anti-theft device(No Battery-No Start).

i dont understand why you need to have an isolator or switch on factory applications ive seen, semis, dump trucks, farm tractors the dual batteries are just wired in paralell is there something wrong with this method or am i missing something here ?

The point of two batteries and the isolator is to keep the main battery always "fresh" for starting. You wire the second battery to run any accessories. This way you can run batery #2 dead and still be able to start your truck and go. HTH.

I thought it had to do with how the batteries charged. I understood that they don't charge properly without the isolator. But other than that, keeping one as a reserve is the idea. If you come out and your battery is dead, hit the switch and go. If you don't have the power to start the engine, hit the switch and go.
That was my understanding for the relays / switch homemade setup anyway.
