MPPT not working after a shortcircuit

Hey all.

We have a portable solar system to charge our electric van when not around charging stations. Today we had what we assume was a short circuit caused by a faulty cable - there was light when connecting and then smell proceeded. We immediately shut the system down, and changed the cable, but after reconnecting no voltage was showing on the Victron app. After troubleshooting we figured out that the problem is with the MPPT (Smart Solar Charge Controller Victron Energy 150/70). The blue light (Bulk) is still on so it’s not entirely dead. Could anyone give some tips about how to reboot MPPT or what else we could try?

There are some pretty easy to follow tests here.in the pre rma document.

Do you have any fuses or breakers that need checking.
