The first thing I suspected with multiple sensor problems was wiring, so I checked it and saw nothing until I pulled the air filter and saw severed wires. Even before that I wanted to replace the entire harness but a few dollars short. And I replaced the speed sensor because it was easy and didn't cost anything.
So my meter had a blown amp fuse and I fixed it. Able to do drain test. I posted pics in the same link above, but get this.
Soon as I hook it up, it reads. 0.85 amps for about 15 seconds then goes less than 0.05. So I pulled fuses during each 0.85 interval and then disconnect and reconnect and pulled more. One fuse made it immediately go down to normal. The battery main fuse 1. I pulled it several times and watch the amp drop then go back to 0.85 after plugged back in. Doors opening did not change the load, but...
Another thing I've noticed is the battery dies if a door is open for more than five seconds... Which makes no sense since I pulled the interior light fuse a month ago and they don't come on at all.
For example, today I charged battery, drove five minutes to gas station, returned in ten and it started right up. Drove back and opened a couple doors to unload cargo and it was already dying with the clicking not enough amp sound trying to start it.
I can't make heads or tails of it. There is a pattern to the behavior but not one that I recognize.
