Bad rectifier?

[jeff7599]

1996 88 hp SP<br />6 amp unreg.<br /><br />Any harm in running my engine with a bad rectifier. Im not sure if I have a bad rectifier or not. Im not sure if Im using my ameter correctly. Im going to have a friend test it next week with his. Question is, if it is bad, is there any harm using my boat this weekend? I have a new battery, and notice after several hours of running the motor at low RPM, and the running lights on, my lights go dim after a few hours. Basically I have a low load, and the lights still go dim after a few hours of running the motor. Oh yeah, sometimes the tach gauge drops to zero at high RPMs, like above 3000.

Re: Bad rectifier?

Sure sounds like a bad rectifier. Tach problem is an almost sure indicator.<br /><br />Don't believe you will damage anything but the longevity of your battery.<br /><br />And you may get stranded if you drain the battery.

Jeff..... Running a engine with a faulty rectifier prevents the AC voltage being emitted by the stator (under the flywheel) to be converted to DC voltage which is needed to charge the battery.<br /><br />The stator is constantly producing this AC voltage, and with a faulty rectifier, that voltage backs up at the stator resulting in overheating and a meltdown of the stator which in turn results in erratic ignition among other problems.<br /><br />Bottom line.... Correct the problem to avoid additional problems.

Joe,<br /> could this explain why my stator went bad about 2 weeks ago?

Re: Bad rectifier?

I had a bad rectifier/regulator... the tach did not work but the recharge did. My mechanic informed me that their are 2 parts... ususally both break together but in some cases only the tach will go out. I like having my tach as I am always sensitive to performance and maintenance

Very interesting.
