Over the last week, lights have been installed to the roof. The LED roof strings will run from DC boards this year, and unfortunately initial tests showed some kind of electrical leakage problem within one of the strings somewhere.
This has resulted in the loss of one of the four white triangles, and I am urgently looking into ways of getting a replacement at short notice (10 metres long).
I’m still not sure how the light set could have been pulling so much power (ten times the amount it is supposed to) without even lighting up.
Combined with the DC power supply problem earlier this month, DC is sure appearing to be stubborn.
