Looking at wiring diagram "E" in Bentley's, for the 71 Type 2, I note two fans, V2 and V2, wired to fan switch, E9.
However, the legend at the bottom of the diagram does not mention any V2's. Only a V -- the windshield wiper motor.
The legend *does* mention a Y2, as a "fan motor, front."
But the diagram does not have a Y2, only a Y, which is presumably the clock since clock lamp L8 is shown lighting it.
To the best of my knowledge, my 71 bus (chassis number 221 xxxx xxx) does not have a fan switch or any fans, so I suspect that the diagram is wrong on a few counts. Enough guys have pored over these drawings for enough years for any errors to have been noted -- has anyone posted a correction sheet?
