Catalina 34 Starting Battery Problem
I recently purchased a 1989 Catalina 34 with a 23 hp Universal Diesel. I was having a problem starting the engine on the cranking battery so I put in new Interstates for both the house and cranking battery. I have a good West Marine shorepower battery charger that keeps the bateries fully charged and I have checked the batteries with a hydrometer. All is OK. My problem is that even with new batteries, I cannot start the engine on the cranking battery alone. I always have to use "all" to get sufficint power to start the engine. Has anyone else had this problem on a similar boat? I am not sure if I should be looking for corrosion on the wiring terminations or if there may be a deficinecy in the original Catalina wiring?
Thanks for your ideas
