Red Battery Light?

[Shonky]

I would not run it with spikes of 18V if that's really happening. Actually measured it? Asking for trouble with all sorts of modules.

Yea I am not thrilled about that either and have not had time to diagnose it yet. I'm not driving it right now because the other day, the crusty old original east coast exhaust bolts between section 1 and 2 let go, so the car sounds like a Prelude with a broken muffler LOL. It's just one thing after another with this car. My plan is to take the battery off and measure voltage on the battery itself, and then put it back in and fire up the car and test again to see if it reads high.
