My apologies if this is not the correct way to ask if anyone has schematics for this spotlight. Would like to fix it rather than purchase a new one. It has two modes of intensity, high and low. The low mode works fine but the high mode only flashes on once for less than a second then shuts off. There is a small circuit board inside but I need the schematics to troubleshoot the problem. Thank you for your time. Mark O.
