Not necessarily but it will have to be repaired.
Using a DVM,Follow the volts with the key on and using the frame as the meter ground.
Probe and measure the volts at....
The battery negative post
The battery positive post
The 2 big red wires attached to the starter solenoid
The fuses.
Remember..this is with the key on.You will need to charge the new battery too.

What you should find when testing.
Battery negative post...zero volts
Battery positive post...12 +
Big red wires...12 +
Fuses 12 +
This is measured to the frame.
Your voltages should be between 11 and 13 volts at these points.

The solenoid wires.Theres 4 of them in the plug.The larger red ones should both have 12volts on them when connected to the solenoid.
The solenoid has a bonding bar at the bottom of the contact blades.It connects to the dogbone fuse and then to the battery post.
Touching two fuses together and the lights came on.
I'll bet one fuse is for the acessory circuit and the other is main power.All fuses should have volts when the key is on.If only one does,wiggle the ignition switch,its likley your problem area.The switch contacts that provide power on the rest of the fuses are on a black wire from the switch.
Its possible the plug at the bottom of the switch is having contact problems also.
