I received my cheap eBay digital voltmeters today. They are great except for the wires being as thin as a strand of hair and breaking off the board. All three did that LOL. No sweat, I fired up my soldering station and attached some much better wires for my needs. Considering I spent $4.68 with shipping for three of these, I have ZERO complaints.
So, I cut my panel and wired them up. Very nice and I tested all of them and they are consistent in their readings.

The best part? I dialed down two lanes to 7.15 volts (pretty quick and no de-slots), dropped a few of my tuned Scaley GT-40s and P4 Ferrari's on and took them on in another GT-40. Running about 7.25 second laps, an hour and a half later (!) I figure I ran close to 900+ laps!!! What a blast!
While I loved my old PDR track, I have to say that the fetching Mrs. Reinecke was 100% correct when she asked me to re-think the squeezes and tight curves. This track has a fabulous rhythm, is quick enough, technical enough, and just a joy to drive. I'l have to take her out to some high-dollar dinner now probably, or she'll never let me live it down.
