Re: Digital vs. Analog engine gauges
That's great. Apparently they've got two well-behaved LEDs in there then, pulling 35mA. Which would still 25 amps if left alone for one month.
Similar to a car stereo or alarm system or old clock, enough to impact a less-than-perfect battery, but small enough to ignore for a week or three in healthier system, like the 90AH they mention.
