Hi All,
I often visit this forum desperate for advise and information regarding some problem i experience on my boat. I found this forum to be my best source of information for making the right decisions.
This time i'd like to share some info i've recently acquired whilst troubleshooting my electrical / charging system - Subject - Rectifier / Regulator Box
My engine is a Farymann Diesel with an internal magnet / coil alternator arrangement. After installing a voltmeter on my newly acquired boat i figured out that this read 12volts regardless if the engine was running or not which made me doubt if i'm charging my battery at all.
First step was to check the output of the alternator; got a reading of 40 to 100VAC depending on RPM.
Second was now wiring from the alternator to the rectifier / regulator box which was ok.
Third step was checking the output of the regulator by means of a simple multimeter; reading was about 4 VDC; not enough to charge with.
Last and final step was to try get a replacement box. After some research on the internet i found out that these rectifier / regulator boxes are reallly manufactured for motor bikes; Ducati and Honda being quite big suppliers. In fact i later found out that Farymann purchases their's from Ducati.
So to cut a long story short i purchased one from the motor bike people which cost me much less than what was quoted by the engine manufacturer.
Hope this could be of help to anyone experiencing same problems like i had.
Cheers
Tyrone.
