I have a 1999 regal boat with a 4.3 gi volvo penta. We took to river and battery was dead. Exchanged battery with another but accidentally switched terminals. After that we had no spark and no jetting of fuel to the carb. The breakers are not tripped and I do have power to the purple wire going to the coil. This motor has the computer module 3857324. Do you think we fried the module when we switched terminals or is there a fuse link protection we're not finding?
