Low starter battery voltage

[sailcruiser]

Hi papabruce,


Look into one of these:
http://www.xantrex.com/power-product...y-charger.aspx

Then make sure you are wired as follows on the battery switch

House bank to one switch

Start in the second

Charger charging house bank with echo charge to start.

Alternator charging house bank.

Leave the battery selector to house and starter is wired with start battery.

Then you should only need to mess with the switch to turn it off. I have a diagram if this somewhere I will try to find and post.




I believe this is MajneSail's diagram. Hopefullyy brain got that straight above.

Thanks Sailcruiser! I have been able to recharge the battery!! The controlling battery switch was in the incorrect position and the starter batt was not being charged. I put it on a trickle charger for about 24 hrs which got it from 2.4 vdc to 6.8. I could then switch it on at the battery switch and let my xantrex take it the rest of the way. At 2.4 vdc it set off the low battery alarm when I switched it on. Getting up to 6.8 vdc solved that.

Thank you all for your input.

Glad to help. I have been in a similar process. Be careful with the battery switch and know where it needs to be when under motor or else you may blow your alternator out. I'm not sure what people were thinking when they wired ours. I prefer not to have to worry about it with a so many other things to check before departing.
