My port cooler is a lot more brown then the strb. What could that mean.

[David Carter]

It’s a Hi-Star 47. Seahorse. Made in tawain built heavy I believe over 50000 lbs.
2004. It’s got a bow thruster an stabilizers

[David Carter]

I also don’t know anything about stabilizers. Any help on maintaining them or dangers of them If you notice the one stabilizer gage has a broken needle. The previous owner said he ran them to keep them operating. Also the hynautic steering can I don’t remember how much pressure they’re supposed to have. There must be one for shifting also I haven’t noticed it yet.

1 stabilizer and a fluid box in support of not sure yet what goes in or how much
The door goes to the back of washer an dryer
2 hot water tank and expansion tank
3 front port side of strb engine
4 engine info
5 top of strb
6 center isle
7 port side of port engine. Looks like something is leaking.
8 possible belt size on engine and the hydraulic pump.
I’d also like to get the digital meters you recommended. Which should I get I’m not sure if I should get three with a panel to mount them in. I would like recommendations on the cooler kit I need. Do you see anything in the hoses. The wires on the exhaust I don’t where they go I haven’t found any gauges other then the normal volt meter temp, oil pressure.
Any other things you would recommend to add. I tell my grandkids im as broke as a bag of glass. But I can’t afford to have another boat burn up.

I really appreciate that I can post these questions and to have someone of your caliber to answer.
Under Tony’s tips in the electrical section you have typical dc distribution.
I have a manual switch on the combiner and I disconnected it. When I check voltage with the engine running there’s only one battery being charged. I’m getting the leads labeled. I ran each engine and checked the voltage on the batteries. The engine batteries are stand alone unless that combiner is engaged. I also ran the inverter and the other three phase charger separately to label what is charging what.
I’m trying to figure out the items on the engine. The ones I posted pictures of. They look like relays. I see one is the aux. mag switch I see it on the starter crank fuel solenoid schematic but not really sure what it’s for. Also what is the alt. Diode do It’s next to the 10amp reset button in my pictures. I see its changeable I’m wondering if it could cause my problem.
It may be a couple of days before I can spend much time tracing the system. I’m going to try to sneak over and take pictures of the whole engine room. I want to do any maintenance I can to prevent any future problems. I need o rings and lube for the the aftercoolers. Maybe belts and hoses. I’ll Start another thread for that. I don’t have much on my specific boat and systems Hi-Star 47 I’ve looked on the net but nothing out there.
So again thank you so much I will purchase as much as I can from your company.

I just looked at your typical dc circuit for twin engines. I got the idea if that’s the diagram your looking for I think mine is close to that. I had a house bank of two 8ds and a separate inverter bank of two 8ds. I was running out of inverter power in less then 8 hrs so I connected the house and inverter banks. Most of my stuff was running off the inverter and only a few lights off the house. I will try to trace my system But that’s four batteries and I have one for each engine with another in the bow for my thruster. Also a 27 for the gen.

[David Carter]

I spent the yesterday tracing my batteries as far as what charger is charging what. I have an inverter that charges and also a phase three smart charger. Not to mention the 22sl alternators. I turned both charger off and still had the 14.7 output from the alternator. The alternator 22sl has a negative and what I believe to be a two prong plug for an internal regulator. There is only one wire coming out of this connection it goes into a connection that has a red an black leaving and going into a harness that raps around engine with many splits and relays I’m guessing. Each engine has a single 8d that is either isolated or switched to parallel. The hot from the alternator goes to the starter and that sprouts other hots Anyway I will do what it takes to track down the problem. I’m not sure the best way to proceed. Must I strip the harness and track each wire thru out. Or maybe add a jumper to my ohmmeter and try to find the other end of each lead. What a mess. Would there be a way to check the internal rectifier like maybe I should take the one wire coming out of the two prong connection on alternator and run it to batteries or just disconnect and look for a response. Looking on YouTube I see someone had a similar problem and hook up an external rectifier. There’s not much about an alternator that continues to charge most are about under charging. It’s puzzling that with the heater hook up the output swung 12 to 14.7 and with fuse out of heater it’s constantly 14.7. Seems like the rectifier was switching with the heater. I was thinking of switching alternators but I don’t want to fry the other one. But stripping the harness to trace the wires is going to be a mess. So if there’s any easier checks I could do before tearing things up I’m in. Please I’m not complaining and will follow your guide. I have more projects to do this winter. Like cleaning after coolers and anything that should be done after a thousand hrs.
