I'll throw in another question to add to the rest. Since I've owned mine, on occasion the charging circuit doesn't charge system, then does and on one occasion the new tach went down then a minute or two works fine again. I have been thinking about changing that rectifier/ regulator but this reading this thread that doesn't seem to have fixed anyone's problems in that area. Very interesting. Anyone had intermittent problems with it?

I do have a voltmeter on my console and I have also been taking voltage readings with a multimeter. It seems that once I've recharged the batteries, they are now staying charged evenmthough the readings at the batteries never exceeds 12.44 VDC. When starting it drops to 12.2 volts and then comes back up to 12.44 volts when running. It's been over a month and I'm still able to start the motor and I've been out quite a few times in the past month. I was told by another boat owner that the older 2 cycle outboard reulators don't send back a high voltage and only supply a trickle charge. I don't know how true this is, but it seems like my batteries are now recharging.

True, they only supply a trickle charge but it should increase voltage level by at least a volt when running. However if you have an accessory that is pulling current beyond charging capacity, say a bilge pump that's stuck on it would not show a voltage rise . Maybe disconnect hot wire to accessories and see what happens. Or check for anything running that shouldn't be. There should be an orange wire going to first switch on back of instrument panel that then piggybacks to all the other switches. Disconnect that then read voltage before and after at battery with meter.

I have an old two stroke an it boosts to 14 volts when running.

I think you have a very borderline situation. Most batteries should charge to 12.7 v at least. I wouldn't think that would be good for the life of your batteries. Acdaddy, your intermittent problem is likely a loose connection. I had the same thing happen and I want to say there was a post on the back of the tach or one of the gauges where all the grounds connected together that caused my problem.

Most motors have a 15 amp alternator. That is a lot more than a trickle charge. Your voltage should come up higher to maintain your batteries long term.

That's a good suggestion about disconnecting the accesories. Nothing seems to be running that isn't supposed to be, but that's not saying I don't have a short or ground somewhere. My accesories are also fused. Pulling the fuses should give me the same results as lifting the hot wire. From all the replies it sounds like I should have a higher reading at the batteries. I just haven't found out why yet.
Thanks for the help.

You said you checked the voltage at the regulator/rectfier, right? I think, we talked about that earlier.
And its reading 14+ volts?
If yes, then take the multi meter down by the battery and stick the leads into the actual wire rather than testing the terminal/terminal connectors, you can get very differnt readings.
To your other question, yes pulling the fuse breaks the load.

Thought of you after having too much voltage on the boat this weekend.
Did you ever firgure this out?
