OK - I''ll bite !
TP4 is 7.3VAC for GI - F5 (20Amp) - Yellow/Blue Wire directly off the Transformer Playfield, Backbox and Cabinet
TP1 is 5.4VDC for Feature Lamps F1 (10 Amp) - Blue wire from BR1 & R2 (25 Ohms) - Playfield & Backbox
Two different circuits, two different voltages (AC and DC)
You have a short somewhere in your wiring loom I suspect, and you need to isolate where the short might be.
Process of elimination - and I assume the machine just sits there and blows a fuse;
Try just the fuse for F5 without F1 - Does it blow ?
Try just the fuse for F1 without F5 - Does it blow ?
this will isolate which circuit we should be looking for - AC or DC ?
