Found I didn't have the LCD re-connected properly - only 3 pins contacting (unplugged it to remove front cover). Unit is now working and charging the Bolt. Still a concern that it blew a fuse. Will see if it happens again.
Glad you figured it out. What current are you charging the BOLT? With 30A fuses you should not charge any higher than 24A Continuous.

I built this EVSE as a kit at a workshop in SF east bay around 6-7 years ago. I used it to charge my converted EV for years. Just bought a Chevy Bolt and plugged it in for the first time yesterday. It charged for around 1 hour, then I went out and saw "Charging Interrupted" on the DIC, and no power to the Open EVSE. I found one of the 30A fuses in the EVSE was blown. Replaced it, but the unit does not power up. I measure 242VAC at the input terminals to the DC power supply. Any ideas on what is wrong? Thanks, Tom
