Thank you sir. Heres something else thats all in the details. If you notice theres someting glued to the back of the gage with a grey adhesive, and red and black wires. Thats a 12V red LED. I drilled a #50 drill (tiny hole) to the left of the discharge side of the gage, and glued the LED from the back. My alternator is a mini denso 50A for small block chevy. I made my own brackets to install it. The denso has a plug on its internal regulator for 2 wires, an ign hot feed to excite it, and a discharge light. So on startup the red light will light up until the engine starts, then go out when alternator starts outputting unless theres a charging fault, then it will light up.
