Hi Redfish - how slowly? I realize it probably varies - but it does take a solid 10 seconds or more to climb up to the high end of the gauges. They're not particularly jumpy, though.
I've never actually timed the needle swing. Best guess is 3 seconds
The mechanical limiter would send full 12 V to the gauges during the warm up so the needle would blast off initially and slow as it gets closer to where it's going. My concern isn't how fast the needle moves. Accurate reporting is most important to me.
