The copy I printed today is hard to read. Does the diagram show where the lw pump out, pump in wiring? I know its a general question, but are there any known problem areas, maybe bad connections that have happened more than once, etc to cause the low voltage issue? When I bought the boat 7 years ago, the problem was severe. Aerator pump would only run for about 30 seconds before the dash turned off. I rewired the junction block and the voltage went up to 12.0 or so. Now with the aerator on, full charge, etc it drops to 11.2-11.4. When going down the lake the voltage will eventually pick up to 12.3 or so but it doesnt happen quickly. Last fall I checked the main + wire and some others for resistance and the ones I checked were OK. Any ideas or shortcuts would greatly be appreciated. Thanks
