MR2510 button housing diodes

Ron,

Herewith a forum page (killed since) with a schematic of the voltage
regulator also describing its standard failure mode.
The MR2510 button housing diodes loose continuity with the B-pole when
the thing gets too hot.
You can see that you need to switch both G-inputs to remove the
regulator from the circuit.

The second picture is the schematic as supplied by the www.pilots24.com forum participant called "Arrow". Whether it is correct I cannot say, but it looks good.
You may credit it to "Arrow"/www.pilots24.com.
