Hello there,
I am in the process of converting my first vehicle. I am really close to being done. That being said, there is 1 last item that is causing me an unbelievable amount of trouble. I cannot synchronize an e-xpert pro display. I have checked the wiring several times and everything seems to check out but I cannot be sure. I have the shunt for the display wired between the B- terminal on a Netgain War-P controller and the non-battery side of my secondary contactor. The unit seems to be working fine when I turn the car on. The unit seems to measure voltage accurately and measures the "negative" current when I drive the vehicle. Contrarily, when I turn the vehicle off to charge the vehicle, the display indicates a negative current of roughly 360amps. As the unit is registering a negative current it does not realize that it is charging when I charge it despite the fact that I watch the pack voltage increase accordingly. I have checked to see if their is in fact a draw somewhere but I do not believe there is. Simply because the draw of 360 amps is too large. In fact, yesterday I watched as the unit counted to a total loss for the afternoon of roughly 3700 amp hours. I only have 3800 total amps hours of storage capacity (38 x 100amh tundersky 3.2V). While this loss has been registered, the voltage of my pack has stayed constant. Any ideas?
