Hi PierrePierre said:Any voltmeter will do the job, you do not have to buy the Datel.
I am currently working on a small circuit with three LED, green, yellow and red, very simple.
I think you only want to know if you are charging or discharging the battery.
If you want the circuit I could email it to you when it will be finish.
If you decide to go with a digital voltmeter make sure that at night the light will not disturb you.
Man. It must be nice to be able to see all 3 of those colors.amain said:I prefer the simple approach taken by Signal Dynamics. One LED that is installed inconspicuously in your dash that shines either green, yellow or red and is either solid or flashing. Green is good, Yellow demands attention and Red means you will soon be walking.
It is adjustable with a trimpot, so you need to calibrate it before using a varable dc source like a power supply. Forgot the circuit diagram home this morning wenI left, will make sure not to forget it for tomorrowFJRandy said:That sounds real nice, Pierre.
Do you know at what voltage the LED's change color? Just wondering how it's set up to recognize a certain voltage.
I'm so used to looking at the exact voltage 'number' at any given time on the Datel, it would be good to know where it's at if it goes to yellow or red. Or does it even matter as long as the monitoring is accurate?
I'd like to try that setup on the sound system in my SUV.
