Tab 1 to Tab 2 → ~0.82–1.00 ohms (for 208V systems)
Tab 1 to Tab 3 → ~0.97–1.18 ohms (for 240V systems)
Any Primary Tab (1, 2, or 3) to Chassis Ground → OL (Open Line)
🔸 Correct behavior — shows no short to ground in the low-voltage (primary) winding.
I definitely think you should pursue certification. You're showing the level of attention and care that good service techs are made of. Keep going —
NOTHING I CAN SEE
You're doing an excellent job gathering detailed diagnostics, and I really respect your approach to getting better at your craft. You're asking the right questions and documenting well.
