Re: Newb Probs with UDC
ok, now I've lost the WiFi link... and 5V out the plug is only 2.3V... might have a 5V issues, probably due to my poor soldering skills.

Unfortunately I have nothing to add to the linked thread. Nissans voltage PWM is either not working or lost somewhere on the way. If you have a scope try finding the signal right on Nissans gate drive board and then follow it towards the main board. Thanks Johu. I don't have a scope, but I'll see w...

Newb Probs with UDC
Hi Friends, I'm "working" on swapping Leaf Gen2 (2013) motor/inverter into an NB Miata (1999). I gave myself a year, and am about 4 months in. I bought the Leaf Gen2 Community Edition , think I have it assembled and installed properly, but am having UDC issues similar to @E46driver here . ...
