Lynx I MkIII purchase

[Alastair Thomas]

My Lynx is now ready for the road except for the fact that the instruments do not work.
I see from the wiring diagram that there is a resistor to drop the 12v supply voltage down to 6v for the instruments. I do not know where this resistor is.
Browsing in the spare parts manual to identify a unit mounted on the front bulkhead of the engine compartment, I see it is called "C19SR 12250 Circuit breaker - ignition coil and resistor assembly". This looks a likely candidate.
Can anyone confirm this is the beast I am looking for and where to test its output please.
Regards,
Alastair
