I have a prebuilt mountain board by a UK builder. I just installed two new vescs and configured them and the wheels run ok and smoothly, but after 30 seconds to one minute and a half of running them on a box to test, the power shuts down. if I turn of the power, then back on, the power drops out quicker, like 5 to 10 seconds when I am running the wheels. The LED volt meter doesn’t come back on unless I power cycle it.
Its wired up to a LED volt meter and a switch and something that looks like a amp shunt. If I unplug the battery from the power switch, LED VM wires and plug directly into the VESCs using XT60 splitter, it works fine. No shut down.
I’d like to keep the power switch and LED VM and charging port wiring for convenience, but I am not sure where the problem is to fix it.
