I am in the process of completing a PS3 upgrade on a FM Virginian with a problematic PS2 5v board and am having a problem with the lighting circuits. For example, the back-up Mars light functions but the forward Mars light does not.
I have tried different PS3 sound files from the site, and have loaded the diesel chain file (which was probably unnecessary). The premier PS3 file offered more lights but again, not all circuits are functioning. The harness connector is fully seated.
I have yet to test load the PS2 sound file.
Thanks in advance for any advice!
