Losing hope

[KamenRider_1500]

An uncommon thing I've seen a few times is the diode in the alternator doesn't turn off and drains the battery. Seen it I think 3 times. Dunno if that'll help you, but it's a possibility.

Because when I took the truck to autozone for them to test it they said everything was running good but I’ll double check on it.

I’ll take a look on that, haven’t thought of it.

It is a very VERY uncommon thing. But it is a possibility. Wouldn't call it a probability. But worth checking.

Every time I've seen it, it didn't test bad. But the diode just wouldn't shut off, and allowed it to drain the battery when it sits

Don't lose hope. You can diagnose this.

Here is what I would do if I were in your shoes.
1. Verify the battery. I know it's new, but take the battery or the truck back to Autozone and have them load test the new battery- just to be sure.
2. If the battery is good, pull the negative cable off and charge the battery with an external charger. This starts you off with a charged battery.
3. Test for parasitic draw. See this video for a tutorial:

4. If after pulling fuses you find something, chase that circuit.
5. If you don't find something, look into the Alternator bridge diodes.
6. If the above does not work; find another mechanic. This should be gravy for a good one.

At night, or when you are not driving it, disconnect a battery cable so you are not worrying / babysitting it until you find it.

Good luck, this is solvable.
Oh, and BTW, it is a good looking ride!

Took it to a mechanic, couldn’t find the issue either

Let me rephrase then, take it to a good mechanic.

I’ll give it a shot. The farm truck can count itself lucky that it can do burnouts.

I appreciate everyone’s suggestions by the way. I’m going to tackle this the best that I can. There’s a small part of me that doesn’t want to give up on the farm truck. I didn’t make a whole build list just for it to go to waste.

Possible short term solution until the issue is figured out, try a quick disconnect terminal so that you can easily disconnect the battery when you get where you’re going-pop the hood, give it a few twists and off you go. Reverse steps when you’re ready to leave again. Standard side post example below, but there are all kinds of variations available.

The incorrect size battery is not a voltage problem it's the amps. It's the amperage that the starter needs to create the torque to spin starter.
This is an electricity problem. Something is still drawing power with key off. Don't wuss out, learn some basic low voltage electricity. This is a problem you can fix. Get a test light, and a digital multimeter. Watch some u tube vids on parasitic voltage draw troubleshooting. It'll make sense then.
As to add ons drawing parasite voltage. To eliminate them pull there fuse or disconnect, just being off does not mean they still are not drawing some low amps or volts.
In this day and age up to half your mechanical repairs , troubleshooting will be electrical knowledge.
Good luck.

Figure out the amp draw on the battery. Pull fuses till it goes away. Your problem will be on the circuit that has the draw. Aftermarket equipment is always the first suspect.
