Should I replace my Stator ???

1999 Mercury 200EFI 0G897614. New week & new problems, I noticed last week that my lower voltage regulator was burnt & I could smell that certain electrical / plastic burning smell. When I took them out, I knew visually it was toasted. I did a little research and decided to check the stator, it pass all the ohm test listed in the manual, I don't have DVA, so I couldn't check the low & high idle volts. But visually, one side the copper is dark & the other side is shiny copper. Something also, drain my starting battery overnight. When I hooked a new battery up, I could hear a click around the stator area and get a big spark as my battery lead touch the battery post. Does the VR burn up the stator or does the stator burn up the VR? Or what could have cause this. I didn't smell this when I first got the boat, but I have had some performance issues


A little about the motor, I just bought in late december. It had been sitting for a few years. I have found several things wrong with it & hoping to get it running better.

I would greatly appreciate any advice. Thanks

yep gonna need both regs and stator, would only use oem also JOE

Thanks Joe. I was pretty sure I needed to replace the Stator from the looks of things. Will I have to set the timing after I change the stator

shouldn't ,wont hurt to check it though,just don't use junk regs

The new mercury regulators have fuses to help prevent this

To prevent from burning the regulators or from burning the stator

both

ANY browned, blackened or burnt Bullet Connectors should also be replaced.

Be sure to verify your battery and connections.

Battery should be a traditional WET CELL Cranking Battery (don't use AGM, Gel, or Deep-Cycle Batteries).

Cables should be ENGINE cable FIRST, remaining lugs largest to smallest, and finish off the connection with a Stainless Locknut (NO WING-NUTS).

A high-percentage of Regulator Failures can be traced to the battery or battery connections.

Don, I saw this when I was researching other stuff. Before I roasted the VR's and Stator. I had a undersized battery, bad connections. I instaled a properly rated battery, took about 6ft of battery cable off (because I moved starting battery to starboard side) and install brand new lugs. The first time I cranked the motor, my stator burned up. I figure the VR'S were already gone.
