    Over voltage (again)

    OK - a little more testing after our day out on the boat. The port alternator is putting out 17.3 volts at idle speeds. So, I think the voltage regulation is cooked. I'll get a new alternator on order. I'm going to do away with the 2 alt/3 battery isolator. It seems a little unnecessary and...

    Over voltage (again)

    Quick update - i disconnected the starboard engine/battery from the isolator. Starboard engine is no longer getting over voltage. We salvaged the day and took the boat out. Stayed close as there is more diagnosis to do.

    Over voltage (again)

    Tomorrow, I will focus on the battery isolator with the port engine running. It has occurred to me that the port alternator is doing the over-voltage, but the isolator is giving the voltage only to the starboard engine. :unsure:

    Over voltage (again)

    I have no idea. Everything is wrapped in harnesses. I'm just wondering where the 16 volts is coming from . . . perhaps the port alternator, but it is not showing up on the port engine controls. Someone on the CY338 group stated that the battery isolator was causing an over voltage on their...

    Over voltage (again)

    I think it may be worth noting if any other voltages change when the port engine starts up. I'll be checking later today.

    Over voltage (again)

    Here is my Diacom recording of the Stbd engine data. Starboard engine started first and then the port engine was started after a short time. . FWIW - The Diacom seems to have Battery volts and system volts labeling reversed within their software.

    Over voltage (again)

    Here is my wiring diagram tracing from an issue that I was chasing last year . . . Just wondering about the Alternator Excite connection/wiring (right side or diagram). But thinking that I see the over voltage only on the Starboard engine. Port engine thinks it is fine, even though it seems...

    Over voltage (again)

    I spent some time out on the boat checking into the voltage issue . . . This got a whole lot more interesting (?) When the Port Engine is running, it causes the over voltage on the Starboard engine (whether it is running or not) The starboard engine running by itself is fine. The port engine...

    O2 Sensor codes . . .

    Just getting back to this thread with some follow-up. . . I replace the sensor (post CAT) and it is all good. The sensor was pretty much disintegrated, which leads me to think that the other sensors may need replacement soon. :unsure: The Post CAT sensor is about $60, but it looks like the...

    Over voltage (again)

    I launched the boat today and within moments of starting the engines, I got an over voltage alarm. I had one during the pre-season prep. I cleared it with the Diacom and it was fine throughout the engine running during the rest of the pre-season. Today it reared its ugly head. Per the...

    Birds in the boat . . .

    IDK . . . the habitat was pretty well isolated, being the ladder pocket of my boat. If anything, it might have been too small for the parent bird to cover the nestlings. I suspect that their demise might have been from the cold & harsh weather, but hard to tell. Not a bird expert, but I'd say...

    Birds in the boat . . .

    Well, it looks like the storm was too much for the birds. This morning, after the last bit of rain stopped, I noticed the parent bird bring food to the nest as they have been doing over the past 1-2 weeks. But then the bird would come back out of the nest with the food still in its beak. This...

    I/O (Sterndrive) Conversion to Outboards

    Well, I know that I have aged . . . I can no longer contort my body to reach under the engines to check the water intake hose clamps. As I was trying to do so over the past few days, I said to myself . . . . "well that just perfect" :rolleyes: I used to not mind maintaining the I/O engines...

    Boat budget question

    Not much building yet . . . more in the planning stages. The Admiral may not remember, but after we sold the house (and got well more than our asking price), she said "now you can get your outboards". :LOL: :cool: I will be working up a (big) budget for that project soon.

    New SeaRay owner (Sundancer 250) with some basic questions

    Having your boat towed without a towing membership or good insurance coverage can get crazy expensive. I have SeaTow (and have used it) which is predominant in my area.
