I've have a power panel that is faulty. The glow output stays at 12v. Has anyone seen a simlar issue themselves and managed to fix it ? I don't have a schematic but I can solder, etc.

It is like the bottom one shown here :

Also, please will someone advise on the use of the glow current settings control and meter and how to make the most of it. Is this really better than a simple nicad glow clip ?
