I have found the reason the choke was blowing fuses. After carefully unwinding each coil i found a small blown area which has taken out about 6 or 7 coils on each coil and blown a hole in the plastic divider. The coils were not physically touching/shorted hense the reason i didn't read a short between the coils on the meter but i suspect when power is applied to the choke this allowed an arch to jump the gap creating a short circuit. Very intresting.
Now i wonder if its wise to remove the other filter choke in the circuit and rewind that one? Even though its measures fine now maybe a month down the line that one will follow suit?
Also any advice what i could fill the hole in the coil divider/centre section with? Can you buy potting in small quantities?
