OK guys, found the fuel gage PWM bug. It exists in both 2420 and 2480 versions of the code.
Open the asm file and remove or comment out line 1622
;MOVWF RES2
That line serves no purpose and somehow got inserted way back in my january code. Probably right after the last time I checked this function..........go figure
VR2 will then work to adjust PWM at 20% SOC.
Jackbauer, I still think you need an inverted PWM for your setup, but play with VR2 and see what impact it has on the gage needle.
