I am working on a 2005 22" Manitou Osprey Pro. Is there any source for obtaining a
boat wiring diagram for this pontoon?
I just recently purchased this and have been trying to fix some
electrical issues. Some are relatively straightforward.
The pontoon's stereo
speaker color codes matched the vendors color codes directly, but the
stereo's power hookup did not - both yellow and red leads from the stereo were tied to a the pontoon's solid red wire. There was also a red wire with a yellow tracer in the same (stereo) wiring bundle of the pontoon but it was just clipped. Is one of the these a direct battery connection and the other one an on/accessory connection? The stereo wiring diagram shows two positive connections one labeled battery and the other labeled ignition - I don't want the stereo on all the time.
The sun has faded all the indications of position for the ignition switch and all the switch/breaker functions. I don't even know if the ignition switch has an accessory function/position.
I don't know if the 5 function switch panel is a standard wiring. Is there a standard layout for the switches?
Since the stereo speakers and power seem to follow the standard color codes for front -rear and power, is it safe to assume all the lights, horn and other accessories follow some standard of wiring? If so what are those standards and where can I find a standard schematic or wiring diagram for those standards?
I can't wait to get out fishing on this pontoon - it has an installation for a trolling motor battery in the console with direct wiring to an outlet mounted at the bow for the trolling motor (no battery installed yet) - there doesn't seem like a way to charge this battery from the engine's alternator/charger. Is there a way to connect this battery to the the engine's alternator but not allow the trolling motor battery to try to start the main engine? I don't what to run the higher gauge wiring for that. I just want to use the trolling motor battery for the trolling motor and accessories when the main engine is not running if that is possible.
I would like to develop a wiring diagram for this pontoon but I would hate to have to start from scratch and trace out the circuits by trail and error.
Any help would be really appreciated.
It sounds like a previous owner was doing some wiring modifications. We know
the Manitou crew very well, and it is not like them to have hidden wires clipped off in their harnesses.
The key switch accessory position question is based on the brand of the engine on your boat. The easiest way to tell is to turn the key switch. It will either have 3 positions (OFF-ON-START) or 4 position (ACC-OFF-ON-START). If the key has an accessory position, it will have an A or ACC on a tab on back of the key.
There is not a standard layout for the switches on your helm. I would consider calling Manitou in Lansing MI to see if they have replacement panels for your boat that would have the proper labeling for the panels.
Here is the common
boat wiring color code used by most OEM boat builders, including Manitou. You should be able to use this to trace down any wires on the boat.
If you want to charge the trolling motor battery while the engine is running,
you will need to run some larger wires between the starting battery and the
trolling motor battery. This wire size is based on the size of the alternator on
your engine. Most
VSR smart battery switch systems are capable of handling 125+ amps but the
limit is the size of your alternator. If you alternator is less than 20 amp, the
VSR is almost a waste of money. You will need to run your outboard at full alternator output for nearly 3 hours to replace what the trolling motor can draw in less than 1 hour.
Hope this helps,
