This blog documents the restoration, and conversion, of a 1965 Humber (Singer) Vogue to a fully electric vehicle. The Vogue will be powered by an 11kW(modified), 3 phase industrial AC motor, controlled by an industry standard Variable Speed Drive (VSD) or Inverter. To be able to produce the 400 volts phase to phase the VSD will need about 600 VDC of batteries. A big thanks to the contributors on the AEVA forum:

Pack #2 LED cooked again

Another minor issue has crept into the Vogue to-do list.
In this post and again in this post I note that the blue LED on Pack #2 in the boot had cooked. When I disassembled the pack and checked the LED was a dead short - both times.

Well it's happened again. It's probably no coincidence that the optically isolated connection to the five packs in the boot feed to the controller input that I blew up about a year ago (this post) - and at roughly the same time as the LED expired the second time. (The controller input fault was a surface mount 1nF ceramic capacitor that started believing that it was part 9V Zener diode - weird.)

So I will build another BMS Monitor Board and totally change out the one that appears to be blowing LEDs (and controller inputs).
I'll try to get that done this week after work.
I'll carefully visually inspect and test the one I remove and post the results.
