I have just purchased a used CMC PT-130 unit works great when you jump it dirrectly to the battery in both dirrections. My problem is the wiring, this came out of a project boat where someone disconnected all wires. I have two new 5 pole relays, a new on/off/on switch and have replaced the 30A/12v breaker. When I think that I have it wired correctly I touch the wires to the battery and nothing but fireworks. Can someone please take a picture or draw me a diagram of the wireing. I would be in a great deal of gratitude.

Thanks in advance.
