H40.5 Electrical Schematics - Anyone have them?

[Rich Stidger]

For some reason the set of drawings in my owner's manual notebook that I received with my 1997 h40.5 were missing the electrical schematics and also some of the diagrams that show where the different cables were run and located.

My dealer was able to get me a set of schematics from the 410 model which had just replaced the 40.5 from the Hunter factory, but these don't reflect the h40.5 wiring in many places.

Does anyone have the original h40.5 wiring schematics?

Maybe...

Rich, I have all of the manual, but mine is the Yanmar, and some of those wiring looms were different. Still, the basics should be the same. I won't be at the boat for about 10 days or so. I could scan them soon after. Is that OK? If anyone else has better info, let Rich know.

If it's anything in particular you need Rich or if you or anyone thinks it's of value to others, I can scan the docs and post them under the KB here

I have the basic ones that were in the binder. I can scan and send them over to you on Thursday.

Rick, Dan, Karl,

Specifically I am looking for the wiring between the engine, instrument panel, and the battery combining solenoid that is mounted on the side of the drawer in the engine compartment.

However I would like to have the complete set of original wiring diagrams. I don't know if the ones for 1996 and 1997 were different with the Volvo engine vs the Yanmar. The set I have for the 410 is probably 15-20 pages, so assuming that the set for the h40.5 is about the same quanity that is a bunch of scaning and uploading to the KB. I might be the only one that doesn't have these drawings.

If any of you would like to make me a copy and mail it to me I would be happy to reimburse you for your copy and mailing expenses. Alternatively, scanning and uploading would be great also, but it's probably more work.

I would be grateful for anything.

I have a 1997. Only problem is the boat is in the yard on an emergency haul out. I'm hoping to be out quickly. I'll grab the book and can scan what what I have.

Go Karl...

You are probably Rich's best bet. Good luck on your shaft fix.

Rich,
the wiring diagram from the engine to the panel is part of the Yanmar service manual. I do not have a combining solenoid. Maybe what you are looking for is in the Volvo service manual. All the other wiring diagrams are here.

 

[Marco Garcia]

Does it look like this one..... They probably have the diagram....

If memory serves me right, my book electrical looks like the the diagrams posted by Marco. I have the service manuals as well and will grab them on my next stop at the boat. A better copy of the breakdown can be had at Marine Parts Express:

Marco, thanks for the scans

However these scans show the routing of the wires and cables in the boat. What I am specifically looking for is not the routing but the actual schematic connections of the wiring.

These are useful, however, since I think the routing diagrams that I have are for the 410 and not the 40.5. I'll need to check when I am back onboard. Of course the 410 layout is almost a mirror image of the 40.5, so everything is flopped port to starboard.

Regarding the instrument panel wiring, the component view that you linked is for the standard instrument panel and I have the deluxe panel. Beyond that, the specific wiring detail that I am looking for is the interconnection between the engine wiring and the boat wiring. The engine instrument panel is connected via a cable to the engine harness. Additionally there are connections from the engine harness (alternator, starting battery, etc) that tie into the boat wiring itself- These are precisely what I am searching.

 

[Rich Stidger]

Unfortunately, they only have exploded views of the parts and they don't have actual schematics. I have the MD22L-B Instruction Book, Owner's Manual and Workshop Manual, and the best connection information is a component pictorial that is like an exploded view with wires running between the parts.

Take a look at one of my other posts regarding the engine wiring and you will see the type of wiring diagrams that V-P provides.

I may head down to check out the boat tonight. The damage turned out to be a lot worse than I suspected at first. We'll be out of the water for a while. But I do have to stop over and take a look at the boat and pick up a few things. I have a meeting this afternoon and may head there after that. If so, I can scan the pages tomorrow. If your e-mail is still the same, I can send them on to you. If I don't make it tonight, I should be there tomorrow.

 

[Rich Stidger]

OK, Karl. Thanks.

Rich, sorry to inform you, but like I was told by the chief mechanic for my Hunter dealer, "your boat is number ...(pick a number) of .... so many built. The schematics were only applicable to boat #1. After production starts, Hunter keeps making changes and they don't update any of the drawings. Very frustating at least. I'm looking at my 120- vdc schematic and it's not even close to what I see in my boat. I might as well deep six the books for all the "help" they provide. PS: None of the major wiring is placed inside the PVC conduit built into the boat, but instead run here and there during manufacturing. It crazy when you see this is a new boat and no one has made any changes since it came from the factory.

Karl-
What happened to the boat???

The best we can figure is there was a catastrophic failure of the cutlass bearing. When the bearing failed, the drive shaft shifted and the resulting vibration took out the shaft seal, coupler and transmission. So I’m down until the insurance folks do their survey and then we can start the teardown. The transmission will have to be pulled and rebuilt, so I’m looking at a few weeks of no boat. I’m already having boat withdrawals.
Rich, I didn’t have a chance to get to the boat, but I am headed there this morning. I’ll grab my schematics book when I’m there and will scan the section for you on Monday.

 

[windward54]

Rich, got the book and I'll scan the electrical sections and e-mail them to you Monday. Good news on the boat. The surveyor had a different opinion on the damage. He felt that the motor mounts came out of adjustment and the engine dropped on the port side about an inch. That bound up the drive shaft, causing the key in the coupler to snap and the cutlass bearing to break apart. The transmission appears to be fine but the shaft may be scored. Bottom line, looks like we are back in the water by next Thursday, Friday at the latest.

Karl,

Thanks for your effort on the schematics.

Regarding your shaft issue, I'm trying to piece together what happened from your various posts. Now I am confused- how can an engine mount fail and allow a corner of the engine to drop an inch?

Can you elaborate?

 

[windward54]

I'm not buying the whole story from the surveyor, but here goes. The story from the surveyor:

Somehow the port/aft engine mount became loose. After some time, the vibration caused the port forward motor mount to also loosen. Eventually the adjustment nut loosened all the way down. When I put it in gear the last time, the engine shfted down over an inch to port, dropping the shaft down to where it bound against the tube. The shift also bound up the cutlass bearing and caused it to bind and break. When the shaft dropped, it locked up and the turning transmission broke the key in the coupler.

Like I said, I'm not buying the whole story, but the net result is the same costwise. The only good thing is the transmission seems to be fine.
