115 Inline 6 Stator Problems

I have a 1987 Mercury inline 6 and I started noticing that voltage gauge in my dash was peged out at 16 volts. Then I notice on my depth finder that it was reading nearly 17 volts. I done a search on iboats and noticed that people were saying that these older mercs would put out high voltage so I kind of ignored the high voltage. well to make a long story short, a fried depth finder and two new batteries later I decided that nearly 17 volts was just to much. I checked the rectifier and it checked out ok. Then I checked the charging side of the stator and my ohm reading on the wires coming to the stator was 1.1 and my clymer repair manual said that it had to be below 1. So I disconnected the wires coming from the stator to the rectifier and taped them up so I could still use my boat till i could afford to get a new stator. Also I checked the ohm reading on the wires coming from the stator to the switch boxes and they checked out ok. Now due to the fact that I disconnected the two yelow wires coming from the stator to the rectifier my tach does not work. My question is would it be posible to connect the grey tach wire to one of the yellow wire or even both of the yellow wires in order to get my tach back working.

I have a 76 850el merc. My tach is connected to the rectifier only so that I could hook up with a yellow wire. So I would guess yes. My tach does not run through the rectifier. Just hooks to a yellow wire.

you might be able to add a voltage regulator

The only choises you are to replace the rectifier with a voltage regulator is by far the best or in some cases you may add another battery that is hooked paralal to add enough capacity to the system to hold the voltage down

does anyone know what kind of voltage regulator i need? I did ask around at a couple of local marine parts places and even the automotive parts place and there were so many to chose from that i don't know which one to get.

Laddies right, I replaced my rectifier with a combo rectifier/regulator on my '91 50hp several years ago and have no electrical problems since.<br /><br />Jerry

Are the one's that laddies has listed Combo rectifier/regulator?

Yep - what Laddies said - your stator is fine.<br /><br />-W
