Honda BF10 remotes

rigi36 · 14 February 2016, 17:56

Hi

We've just acquired a boat with a Honda BF10.

The outboard is electric start (though also has a manual starting cord).

The boat has a Honda remote control box. Connected to the control box are the gear/throttle cables as well as a kill switch/ignition cable that runs back to the engine and plugs in under the hood.

There are three connectors attached to the control box that at present are not plugged into anything - I'm guessing this is why the oil/overheat lights aren't working.

What cable do I need to plug the control box into the engine and where abouts does it plug into under the cowling? I couldn't see any sockets spare.

The outboard also appears to start remotely in gear which is a bit worrying - what would be causing this?

I can get photos tomorrow but any help appreciated.

Thank you.

Just to confirm it is the highlighted sockets I have free - i'm assuming it is these I need to plug into the engine to get the oil/overheat lights working?

Im not certain, but I believe those are the tacho connections. That's what they are on my yam. What colours are the wires.

You could be right (see attachment).

If that's the case, and ignition switch, kill switch and the indicator lights are on one connector why aren't mine working?

Kill cord and ignition switch works fine - there's no buzzer or oil/overheat lights though.

Not all small engines have those things (I notice your diag is not for the bf10).

Sorry, I managed to post a different diagram to the one I was looking at.

Attached is the actual one.

As far as I can tell, the lights + buzzer test should be working when I turn the key to first click.

I've only viewed your diagram on my phone. Whilst it looks like you do have a buzzer and sensors etc, I wonder if they are meant to activate during a key turn... Some engines do and some don't. It's not obvious from the wiring how this would activate?

I think on Hondas, the green oil good indicator should be lit when the engine is running.

When I had my BF20 with remote, all I did was connect the moulded plugs within the engine, the buzzer definitely worked, oil light cant remember TBH

Yep, all plugged in but sadly no joy.

Is there a separate fuse for this stuff?

I don't think so. Time to get out your multimeter... Is it an actual bulb or an LED? i.e. could it have blown?

This isn't a new engine is it? Check all the connections and wiring for signs of corrosion.

Thank you.

There's usually a little micro switch in the control box that stops the motor from being started in gear, when these go wrong, they should be replaced but some people just bypass them :-(

I have a bf10 (2006) I can take pictures of the control box wiring if needed?
