Persisting Data with C#

In Unity, I'm trying to save the game data to a file to be loaded upon the game reopening. But for some reason it is not saving and I cannot figure out why.

I have it so that if it cannot find that save file, it gives the player 3 items to start with and then tries to save that to the PersistingData. But then I close and reopen the game and it does not stay, and gets defaulted to 0.

Anyone know what I did wrong?

The PersistentData code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;

public class PersistentData : MonoBehaviour {

    public static PersistentData dataObject;

    //Persistent Data here
    public int amps = 0;
    //Capacitors
    public int cap1v;
    public int cap3v;
    public int cap5v;
    public int cap9v;
    public int cap12v;
    public int cap24v;
    //Statistics
    public int totalDistance;
    public int lifetimeAmps;
    public int totalCapsUsed;
    public float lifetimeTimeInSeconds;
    public int numberOfRuns;
    public int distanceRecordNoCaps;
    public int distanceRecordWithCaps;
    public float highestAvgVoltage;
    public float longestRunInSeconds;
    public float highestAmpsEarned;

    //check if this object already exists and make sure its not destroyed every level
    private void Awake() {
        if (dataObject == null) {
            DontDestroyOnLoad(gameObject);
            dataObject = this;
        }
        else if (dataObject != this) {
            Destroy(gameObject);
        }
    }

    public void Save() {
        //setup for saving
        BinaryFormatter bf = new BinaryFormatter();
        FileStream file = File.Create(Application.persistentDataPath + "/playerInfo.dat");

        //Add the data here too
        PlayerData data = new PlayerData();
        data.amps = amps;

        data.cap1v = cap1v;
        data.cap3v = cap3v;
        data.cap5v = cap5v;
        data.cap9v = cap9v;
        data.cap12v = cap12v;
        data.cap24v = cap24v;
        //Statistics
        data.totalDistance = totalDistance;
        data.lifetimeAmps = lifetimeAmps;
        data.totalCapsUsed = totalCapsUsed;
        data.lifetimeTimeInSeconds = lifetimeTimeInSeconds;
        data.numberOfRuns = numberOfRuns;
        data.distanceRecordNoCaps = distanceRecordNoCaps;
        data.distanceRecordWithCaps = distanceRecordWithCaps;
        data.highestAvgVoltage = highestAvgVoltage;
        data.longestRunInSeconds = longestRunInSeconds;
        data.highestAmpsEarned = highestAmpsEarned;

        //actually writing the data
        bf.Serialize(file, data);
        file.Close();
    }

    public void Load() {
        if (File.Exists(Application.persistentDataPath + "/playerInfo.dat")) {
            print("Save File Found");
            //setup for loading
            BinaryFormatter bf = new BinaryFormatter();
            FileStream file = File.Open(Application.persistentDataPath + "/playerInfo.dat", FileMode.Open);
            PlayerData data = (PlayerData)bf.Deserialize(file);

            //Data Here Too
            amps = data.amps;

            data.cap1v = cap1v;
            data.cap3v = cap3v;
            data.cap5v = cap5v;
            data.cap9v = cap9v;
            data.cap12v = cap12v;
            data.cap24v = cap24v;
            //Statistics
            data.totalDistance = totalDistance;
            data.lifetimeAmps = lifetimeAmps;
            data.totalCapsUsed = totalCapsUsed;
            data.lifetimeTimeInSeconds = lifetimeTimeInSeconds;
            data.numberOfRuns = numberOfRuns;
            data.distanceRecordNoCaps = distanceRecordNoCaps;
            data.distanceRecordWithCaps = distanceRecordWithCaps;
            data.highestAvgVoltage = highestAvgVoltage;
            data.longestRunInSeconds = longestRunInSeconds;
            data.highestAmpsEarned = highestAmpsEarned;

            file.Close();
        }
        else if(!File.Exists(Application.persistentDataPath + "/playerInfo.dat")) { //If no save file, default the settings
            print("No Save File Found");
            dataObject.cap1v = 3;
            Save();
        }
    }

    private void Update() {
        print(dataObject.cap1v);
    }
}

[Serializable]
class PlayerData {

    //Persistent Data goes here
    public int amps = 0;
    //Capacitors
    public int cap1v = 0;
    public int cap3v = 0;
    public int cap5v = 0;
    public int cap9v = 0;
    public int cap12v = 0;
    public int cap24v = 0;
    //Statistics
    public int totalDistance;
    public int lifetimeAmps;
    public int totalCapsUsed;
    public float lifetimeTimeInSeconds;
    public int numberOfRuns;
    public int distanceRecordNoCaps;
    public int distanceRecordWithCaps;
    public float highestAvgVoltage;
    public float longestRunInSeconds;
    public float highestAmpsEarned;
}

And the Script trying to access the code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class MainMenuUI : MonoBehaviour {

    public Text capText;
    public Text ampText;

    private int capCount;
    private int ampCount;

    // Use this for initialization
    void Start () {
        PersistentData.dataObject.Load(); //Load data

        ampCount = PersistentData.dataObject.amps; //Load Correct Amp Count
        LoadCapCount(); //Load the total Cap count

        ampText.text = ((int)ampCount).ToString(); //Set amp count on UI
        capText.text = ((int)capCount).ToString(); //Set amp count on UI
    }

    void LoadCapCount() {
        capCount =
        PersistentData.dataObject.cap1v +
        PersistentData.dataObject.cap3v +
        PersistentData.dataObject.cap5v +
        PersistentData.dataObject.cap9v +
        PersistentData.dataObject.cap12v +
        PersistentData.dataObject.cap24v;
    }
}
