Dt85 how do I attach the battery to the charging circuit.

Ok so just got this new to me 1991 dt 85 starts and runs fine. Only thing I can't figure is where I connect the charging circuit from the engine to the battery?
It came with controls and the starting cables to attach to the battery but not the wires to charge it. I sadly don't have a diagram and so I can't figure out the circuits. I found one pdf manual but the resolution was to poor to read.

Surely it just charges via the battery start cable?

Was not sure on outboards if they used the same cables to start as to charge. Now that I really think of it it's a stupid question. Have re wired and re-harnessed cars and a good few motor cycles. Not sure why I was thinking the connection would be different. I guess the three solenoids threw me off.
Oh and I am originally from California probably the lack of sunshine getting to my head, the battle is real!

The starting cables are the charging cables. Current flows one way when starting (12-odd volts), and the other when the alternator is running (14-odd volts.)

Thanks for the help. Also while I have all your ears, or eyes I suppose, as you are probably reading this.
After setting up and connecting my controlls the buzzer/alarm is no longer working. Everything is connected properly nothing is disconnected.
I tested the alarm and it sounds if I directly connect it to 12v. So not really sure what's going on. The only thing I can figure is I switched the shift lever on the the other side of the controlls because that's how it fits on my boat but all the connections are sound. Am I missing something... Besides a few extra IQ points?

"no longer working" = it was working but now is not?

some engines buzz before starting (to test the buzzer) others do not. If its definitely faulty then all you can do is get the multimeter out and start the detective work for the dodgy connection.

Bear in mind if the buzzer works it may be the sensor that is goosed. On your car the oil pressure light comes on before you start the car. It does that to show its working, but it's not wired in a way to test it, it's wired to the oil pressure sensor which with the engine off will be low... Does that make any sense? So the buzzer on your engine means something as you start not just the buzzer works but something like low oil pressure. The sensor could be faulty... I'd check the wiring from the sensor reaches and activates the buzzer if it does I'd check the sensor

Ok so this makes total sense because I had the water float sensor taken apart because I am replacing it. Just replaced it last night so will plug the battery in and check again.
