diy-wb shows lean

[Joshua Ely]

 I don't think that it is because the heater circuit failed.
The egt's of a wot 1/4mile blast is hotter than the temp of the
heater circuit. So the egt's should have keept the sensor within
it's reading range. Possibly when the voltage dropped the "whole"
wb module got affected and changed the voltage output.
