My motor isn't getting any spark to the plugs. I spotted a FAQ that says test electric system and I'm wondering how to do this. Is there a wiring diag (or color chart) anywhere? I found a bad fuse and replaced the AVC #5 250v fuse under the dash of the pontoon. All red wires at battery show good. Starter is turning great. What color are the kill switch wires at the motor. They seem to be ok under the dash. I've unhooked the big black electrical harness and reseated it to make sure it was getting good connection. 20 amp fuse on side of eng. is good. What are the two 1" x 1" black elec. boxes inside the motor case around behind the motor under the spark plugs? Can they be tested? We went for a long ride on the lake and decided to stop for a swim. Motor wouldn't start after we got back on the boat and had to get a tow back. Any ideas?
