The problem I am having is you have early Cal version .

But , I show BM fuse 7 and BM feeds N59.
And fuse 9 feeds N59 for power,

So, you may want to go to N59 and see if you have 12v at pin 4 [ rd/gy]

Check each side of both of those fuses w/test lamp, but on the fuse holder, not the fuse ends.

If you have 12v at pin 4 of N59 and No CE lamp when key is ON, I suspect the N59 module, not the Base module.
I also show 4 fuses on BM..but that is 93 schematic.

May want to check some grounds too, b/c you still should have 12v at pin 3 if fuse 9 is good. You can tell that by using bat neg instead of chassis ground. If you have your 2v w/chassis ground, but 12v using bat neg, then you have a bad ground [ brown wires]
