This is the rectifier/regulator I figured out after I got home from Ray Roberts yesterday. I got in the boat to take off and smelled electrical burning luckily. Looked back and saw a little smoke. It never caught fire but had I not smelled it it looks like it could have. It is an older boat and I often say I have not had any trouble out of the motor which is a 93 150 Fast Strike but I guess it is time for parts to start failing. Fished on the trolling motor only for a few hours and boated around 10 with the biggest about 3 lbs. Fish were getting active and biting good when I left at about 4 but had to get to a family party for the 4th. Be careful and take your safety equipment, you never know when you will need it!
