Hi, I've built this and it works fine until I connect the motor, then it goes a bit pear shaped and the PIC randomly starts resetting. Without the motor the relays trigger fine and the voltages look good, but there must be a spike causing the reset. My other thought is cross feed on the board.
The transistors are BC337 and diodes are 1N4004 across the relays and these may be the problem, but I though I would ask if I have missed something else as well before I starting to switch components out and making a new board with better separation. Uses a purchased 12 to 5 volt regulator.

Thanks for looking and helping.
