  Bryan1 said  Ok the resistor bank voltage matched BV and settled 4 volts below the PSU voltage, now when the nano is turned the voltage quickly drops to 10 volts with a 200mA current draw. So turned it off


So looks like when the TIP41/TIP42's are driven by the nano, is when voltage (24-10 = 14) drops in the resistor bank, the way I understand it.

The TIP41/TIP42's drive the mosfet gates which are high impedance unless some are leaking/shorted.

I don't want to say this and I could be wrong, but looks like the power board needs some serious troubleshooting.
