Thanks, Paul. I guess I don't have late enough schematics; none of mine show that resistor. .... Oops. Just looked and my [factory] book is MkIV, not MkIV/1500.
So, picking Haynes Brains, I see the "Drive Resistor," and it is only sort-of connected across the distributor -- one lead (Green) connects to ignition switch contact 3 via a White wire, one lead (White) goes to the distributor, and a third lead (White/Blue) also goes to the distributor. The diascratch makes it look like the White and White/Blue leads attach to the distributor ground terminal. The drive resistor is covered in Chapter 4, Section 15 (and mentioned in Chapter 4, Section 2.) "Covered" is perhaps too generous a term -- "This is a remotely sited component of the ignition amplifier unit, its purpose is to function as an essential requirement of the amplifier transistors." i.e. you need one. Since there are three terminals, one of which is electrically "hot," it would appear that it provides pullup or bias to a couple of devices in the ignition amplifier. So, anyone willing to pull out an ohmmeter and give us three resistance readings? With all wires disconnected (please don't forget to label where they attach, 'cause I don't know!) Green terminal to White terminal, Green Terminal to White/Blue terminal and White to White/Blue? I'm just curious. And maybe even voltage readings (to ground) from each terminal while the engine is running. Again, just curiosity at this point.
