1. Thanks for the reply Tony. The core had calcium build up on the water side, and the fins were dirty from sucking in the blowby gasses. I (wrongly) assumed that an acid wash was common practice based on my years of experience sailing deepsea. The housing is serviceable I think, but am having a machine shop take a few thousandths off the mating surfaces to ensure good sealing. I have a cpl 1975 6bta, in a downeast boat, cruise at around 17kts at 2350 rpm. 

 

Thanks,

 

Chris

Gents,
Thanks for the replies. I guess I misspoke regarding the combiner, its just a 1-2-Both battery switch, not a load activated combiner, so the troubleshooting of that is much easier. The 12v distribution system is pretty basic, Im leaning towards the grid heater circuit. Im putting in new batteries this week and will work towards isolating the grid heater and installing the pan heater I got from Tony.
