Lynx I MkIII purchase

[James Gosling]

Hi Alastair, I have the same bracket on my Lynx and as far as I know it is for the compass. Although by the time my Lynx was built January 45 a sun compass might have lost its use!!! I had the same mount on the Fox as well but not on either Otter.

Thanks everyone.
The Cole sun compass shown is very different to the one we have (dated 11 January 1940).
I am in the middle of making some Bagnold sun compasses and have been visiting the IWM at Duxford to study/measure/photograph the original. I will post a picture when they are completed.

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

If the circuit is anything like the Ford CMP and MC 6 Volt circuitry, the resistor is to drop the voltage to 4.5 volts for the ignition coil.

Doubtless other Lynx owners can help with more detail.

You can by-pass that and depending on whether you are using a resistor at the coil end, which gives you the same effect. Cheers Andrew.
