Nikimat Amel Super Maramu 2000 Tricolor navigation & anchor light connection

Amel Super Maramu 2000

Tricolor working
Anchor Lights not working.
After posting http://nikimat.com/mast_tricolor_anchor_light_connection.html I Learnt the "black box" was a voltage regulator. The same component were not available, so I purchased other.
After many tests, I concluded the new voltage regulators were faulty and connected the wired directly.
Now the "Tricolor" light is working
The Anchor light is still down.

Picture below:
In the electrical compartment (near forward head) I have identified the following:
Coming from the 24 Volt Panel:
Red wire going to Tricolor (labeled "T" with blue tape) which I call 1
Red wire going to Anchor light (labeled "A" with blue tape) which I call 2
"Negative" which I refer to "5" (Yellow arrow 5)

Picture below:
I disconnect both red Wire (1) and (2)
Test 11 (Tricolor OFF and Anchor OFF on 24 Volt panel)
Voltage from Tricolor Red Wire (1) to Negative (5) = 0 Volt (which is normal)
Voltage from Anchor Red Wire (2) to Negative (5) = 0 Volt (which is normal)

Test 12 (Tricolor ON and Anchor OFF on 24 Volt panel)
Voltage from Tricolor Red Wire (1) to Negative (5) = 25.94 Volt (which is normal)
Voltage from Anchor Red Wire (2) to Negative (5) = 0 Volt (which is normal)

Test 13 (Tricolor OFF and Anchor ON on 24 Volt panel)
Voltage from Tricolor Red Wire (1) to Negative (5) = 0 Volt (which is normal)
Voltage from Anchor Red Wire (2) to Negative (5) = 25.94 Volt (which is normal)

Picture below:
From the mast (coming in grey sleeve)
Green/Yellow wire to "Tricolor" light
Brown wire to "Anchor" light
Blue wire going to the "Negative"

tricolor mast light

Picture below:
From the mast (coming in grey sleeve)
Green/Yellow wire to "Tricolor" light (Yellow Arrow 3)
Brown wire to "Anchor" light (Purple Arrow 4)
Blue wire going to the "Negative" which I refer to "5" (Blue arrow 5)
Now connected directly together:
1 and 3
2 and 4
Negative wire (blue arrow 5) still connected to Negative refer to yellow arrow 5

Test 8 (Tricolor ON and Anchor OFF on 24 Volt panel)
Voltage from Tricolor Red Wire (1) to Negative (5) = 26.14 Volt (which is normal)
Voltage from Anchor Red Wire (2) to Negative (5) = 1.70 Volt (not normal, should be 0)
I can Visually Check outside the light is working.

Test 9 (Tricolor OFF and Anchor ON on 24 Volt panel)
Voltage from Tricolor Red Wire (1) to Negative (5) = 0 Volt (which is normal)
Voltage from Anchor Red Wire (2) to Negative (5) = 26.19 Volt (which is normal)
I CAN NOT see the Anchor light outside.
Note the pictures below:
When I switch on the Anchor switch on the 24 Volt Panel (especially when dark), I can see a little light on the Tricolor and vice versa
I assume it means there is an electrical leak but where?

Picture below:
Other experience, connecting a BULB (which is actually my spare tricolor and anchor light device) to check if the current goes.
When I switch on the Tricolor the light goes on.
When I switch the Anchor it does not.
So obviously the current is not going.

Pictures below:
I climb on the mast. At first I cleaned the connector, no improvement
so I unscrewed the 2 (yellow arrows)
Under was not pretty. So I cleaned it
Unfortunately the "Anchor" plug broke.
