Thanks Neil - and yes sounds similar. I have the smaller acr which has on-board led indicators. I gather you needed the larger unit for a higher output alternator. According to the support docs, the charge source has to exceed 13.7 v for a period of time for the batteries to combine. On the shore charger the batteries see 14.28 v from the charger, and settle at 13.2v fully charged, as do yours. Here’s the installation: http://cncwindstar.blogspot.com/p/blog-page.html?m=1 I missed and will add the ability to monitor the voltage on the start battery, this will give all the necessary info. Off to the alternator shop...
