Both under hood an the one on the driverside dash.

And no change? That shouldn't be possible.

Yup. Hence my problem. Kinda why I posted it here. Lol.

I'm not trusting that meter of yours. Try with just the test light hooked up. Do not connect the meter. I have a funny feeling the meter is acting as a shunt.

With just the test light and the fuses pulled you should have no light. If it still lights then you've got something hooked up without a fuse.

You're pulling the mega fuse too, or the fusible link if the truck has one?

 

[Wyley87]

ALL of them. Even the relays. Only thing that has worked was un hooking the large wire from the back of the alternator.

But that's supposed to be fused. That's what the mega fuse or the fusible link is for. If you pulled the fusible link or the mega fuse (depending on which your truck has) connecting that wire should make no difference at all, it should be dead.

The only thing I can see that connects to the battery that isn't fused is the starter solenoid and the starter itself.

There is a fusible link on that alternator wire. In the underhood box there is a 50 today amp labeled bat.

But that would mean that the solenoid is engaged all the time right?
