Do we have any electrical system guru’s on here?

I had a red light in the dash that was on all the time. It was super annoying, I disconnected it. I wonder if that was the issue. I'd rather have the resistor. They have 560 ohm resistors on Amazon. Would the 2 watt resistors be durable enough for this application? I have no idea. I'd really rather not have to look at that bright red light all the time if I don't have to. Do I need to reconnect the light AND a resistor, or will just the resistor suffice?

2 watt should be more than enough, that 160mA at 12V. You can have just a 560 ohm resistor, you don't need the light. If you had the light and you've since taken it out then that is definitely the source of your issue.

Good thing it wasn't the oil pressure light.

Nah, I knew it was a charge light. However, rather than going on when something goes bad as most warning lights do, it was designed to stay on and then go out when there was a problem. It's annoying.
