winding red wire terminals. Power test machine, FU1 fuse, confirm the presence of T winding short-circuit fault. T each winding resistance as follows: primary winding 1.8Ω, high voltage winding 110Ω, filament 0Ω. Measured with a multimeter R × 1 block of the primary winding is 0Ω, partial estimate of the winding insulation breakdown, short-circuit current increases blown FU1. Because the transformer core is difficult to open, the use of thicker wire diameter, requiring inter-layer dielectric strength between high-level, winding transformers
