Sorry guys, sometimes difficult to put into words. The tests with the meter were done with the battery + side disconnected. I did use the negative side for ground for the meter lead.

The battery is not dead. This is happening driving down the road.

I have no issue putting another fusible link in. My concern is I have a short. As soon as I put a fuse into the holder it blows it if the battery is connected. The other 2 times this happened I replaced the fuse and it was fine for some time.

Trying to isolate the issue with a meter and the readings are confusing me.

If I'm reading 000.0 when I first test and it goes to 000.8 on the meter a second later or so I'm wondering if I'm reading resistance on something inside the car on that circuit or if I have a short on that wire?

Where I'm taking this reading is at the bulkhead connector where the red wire that goes to the amp meter is. I'm confused if the 000.8 to ground is a short or reading resistance in the amp meter or the rest of that circuit?
