"I have a 2000 BF50. The last
"I have a 2000 BF50. The last time out I had a problem with the charging circuit. The first time I noticed it was after approx 1 hour of operation, the tach stopped working & I noticed that the battery voltage indication on my sonar was only at 12.4V It would usually indicate approx 13.6 with the engine ideling. I stopped on shore checked all conections & the main 15 A fuse . Found nothing. The next morning when I started the tach worked & the voltage was at 13.6. After approx 15 min the tach quit & the voltage dropped to 12.3. Now that I am back home I have checked the following.
Charge coil resistance .2 ohms no shorts to ground. I did the resistance checks for the rectifier/ reg nodule as per the Seloc manual & it looks OK. When I idle the motor I get only .5 VAC from the charge coils. This does not change if I disconect the wires from the coil going to the rectifier module or increase the RPM. What should the voltage from the charge coil be at a fast idle? To me the problem looks like the charge coil even though the resistance tests are within spec."
