Re: Mercury rectifier test?

P.S. You should know the metal of the engine is of negative terminal so you have a 4 wire bridge diode[ & not to confuse but Mercury or any other alternator has a wire that goes to the ign switch to turn it off while the motor is off. If that switched wire had an issue the alternator would not charge. Check your manual for which terminals to check to see if that may be an issue. Without switching the alternator off would allow current to reverse & discharge the battery while sitting. /size]
