Hi Jimmy, might be best to introduce yourself first before asking any questions,
no harm done just polite and all.
Have you connected all the earth wires, etc sounds like youve missed something when swapping them over.
Any way welcome to the forum enjoy.
After youre intro maybe post your question in the electrical thread,
good luck TD
