Re: What is causing this alarm on my Honda O/B?'

OK, I checked out the oil pressure light.

It comes on just a few seconds after the motor starts and stays on.

The second time I tried it, after going out for a spin, it did not come on at all.

Re: What is causing this alarm on my Honda O/B?'

Good news:

New rectifier installed. New battery (starter) has 12.5v charge. Goes up to 13.5 when I start the motor. Deep cycle battery has 13.2v charge, Does not change when I start the motor.

Bad news:

Did not fix the alarm.

The only thing left, I think, is the low oil pressure sensor.

We could figure out how many Macs were built by utilizing the German Tank Problem.

Re: What is causing this alarm on my Honda O/B?'

Took her out yesterday. Left the dock just fine. Wouldn't start on way back in. Not a grunt, not a click, not a peep. I might as well have stuck the key in a potato. I assumed I blew a fuse. Sailed into to slip (perfect wind for it, almost rode up on boat ahead of me under power) When I tried it aga...

Re: What is causing this alarm on my Honda O/B?'

Thanks.

It's been running all summer with that alarm so it hasn't done any noticeable damage yet.

But my motor won't run without it in-place so it's got to go back in.

I guess I'll just leave the alarm connector off.

Re: What is causing this alarm on my Honda O/B?'

So, the part is gonna take two weeks. Question: if all it does is recharge the battery, and my motor was running OK, is there any reason why I can't pop the busted rectifier back in* and go sailing while I wait? I recharge my batteries from shore power anyway, so they're fully charged when I go out....

Re: What is causing this alarm on my Honda O/B?'

Incidentally, not really a gear-head, so I am quite pleased with my patience and success in both locating the offending connection and in consulting the manual to find out exactly where it led to. It's a general purpose manual, so there are no less than 20 electrical diagrams - at least six of which...

Re: What is causing this alarm on my Honda O/B?'

Awesome. Thanks for that.

I think I will replace the rect rectifier and just avoid turning off the power when motor is on.

Also, I think I will either recharge or replace my dead battery and, in the future, be more mindful of good, solid battery terminal connections.

OK, here's what I tried: Red probe to black/white connector, and Black probe to... ... grey connector 1: metre reads "1" (I assume that means infinity). ... grey connector 2: metre reads "1". ... grey connector 3: metre reads "1". Black probe to black/white connector, and Red probe to... ... grey co...

Re: What is causing this alarm on my Honda O/B?'

The wire leading to the rectifier is causing the alarm (if I disconnect it, the alarm stops). I assume that's actually the alarm telling me the rectifer's plotzed. There are 4 other connectors: 3 gray and 1 black/white - and a ground. Presumably, b/w is power. http://www.davesbrain.ca/miscpix/sailin...

The alternator on this engine is very simple. What kind of problem do you suspect?
Not charging the battery, of course.

Re: What is causing this alarm on my Honda O/B?'

Plan to head down the dock tomorrow. Of course... the day everything's closed. Hope I don;t need a part. :(

I'll check every connection.
I'll check the battery - see if it's dead. If so, I"ll disconnect it.

Is there anything I can do to root out any alternator problems?

That's because it's a switch, not a sender.
Ah.
'Sender' as in signal. Not 'sender' as in pump.
