I just bought a used Juicebox classic 40 amp level 2 EVSE. All appeared to be great as it charges my 2017 Volt without issues. It will also charge my S10 conversion if I don’t turn up the power past about 4kw. If I turn up the truck charger to 6kw however, the Juicebox will work for about 10 minutes, then the contactor drops out without any warning noises. The Juicebox Classic edition has no display so there is no way to tell what is going on. It does have a beeper which sounds out morse code like error conditions, but I don’t get any beeps and once the contactor drops, I must power down the Juicebox to get it working again. I think it is getting into an illogical state which requires a hard reset.
I’ve contacted the support team at emotorwerks, but the version I have is from about 2015 and there is only one person on the support staff who is familiar at all with my version of the control board. Worse yet, the document archive does not have schematics for the control board, which makes it very difficult to debug. Does anyone have experience with this model of Juicebox or a source for the PCB schematics? thanks, Paul Wallace ’94 USElectricar S10 with serious upgrades _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
