I had a link10 mounted in my S10 Blazer EV's dash http://brucedp02.150m.com/saced02/saced02-04.jpg
When after a very long run when I would approach fully draining my pack, when I stepped on the accelerator, the Link-10's display would blank out (turn off), but as soon as I would ease off the accelerator, reducing the amount of current I was demanding from the pack, the display would come back on (the meter did not rest, just the display had turned off). I had wanted to install a small 12V dc2dc (I am not recommending this vendor, just using their page as an example) http://www.evparts.com/products/street-vehicle/dc-dc-converters--dot/12-volt-input-street-vehicle-converters/dc2410.htm to keep the display going out when the pack was low. {brucedp.150m.com} On Wed, Oct 23, 2013, at 10:00 AM, Tom Jones wrote: > Hi Paul, > > I had a Link10 many moons ago and now a LinkPro.
