Charging alarm question/help.

[NUTMEG]

Thanks for the feed back.

Hopefully now cured although a bit of a mystery why the alarm sounded when both batteries were selected but not when just the starter battery was selected.

I think Id be wondering if both were actually connected or if only the house battery is connected when the switch is in the both position......... perhaps worth checking that out as a possibility ?????

Thanks VicS, now I have something else to worry about . You may well have a point though, I will stick a meter across the switch and check it.

I always wonder what happened next when threads drop off of the bottom of the list and the OP never comes back to explain if it worked, they sorted it out, or whatever.

So, to close this thread, I went back to the boat today, removed, cleaned and refitted all the battery post clamps and started the engine. No charging warning buzzer. I had a hunch that a bit of corrosion on a post/clamp might give a resistance and this resistance might set the alarm off. No scientific knowledge or anything, just a hunch. It seems to have worked. I tried restarting several times and no problems. I hope that's the end of it.

Thanks for your help chaps.

Hi Steve, I am glad you have sorted this. I just thought I would add one comment. Your OP says that your batteries are charged by shores power when the boat is at her berth. I have a newish battery charger and smart engine charging system, and if I fire up the engine and forget to turn off the battery charger connected to the shore power, my charging light stays on. Turn the shore power off and everything returns to normal.

Thank you, indeed shore power and charger were on. But they usually are. I must get in the habit of turning the charger off when starting. If/when the problem returns I will try your suggestion.

Cheers
