Default Starter likes it HOT?!?

I have a dual (24) battery setup with a Guest switch and a Volvo Penta 5.7l V8. When starting cold on battery 1 or 2 alone, I get a single crank but no turnover. Starting on both gives me enough juice to start. After warming up to 160 degrees +, I can restart with either battery alone, no problem. After shutting down and letting it cool about 10-15 minutes, it will start on 1 but reluctantly. A friend's theory is that it could just be a bad connection at the starter and the heat is enough to expand and "improve" the connection at the starter. I have triple checked all battery connections and load tested them, they are good. Before I invest in a new starter, any other ideas I may be missing?

It's not the starter...

My guess is the battery is on it's way out,


you have a bad connector. You say you are checking the connections, but are you REALLY checking the connectors? I mean, I'm sure yoru checking for a clean un-corroded battery terminal connection, but is the battery cable connector a good one? I've seen battery terminal connectors look fine, but when you take them off the battery, and wiggle them around you might find it is corrodded on the inside, where the wire meets the connector. That goes for the starter cable connector as well. Pull them off and make sure they are tight... try holding the cable and then try to wiggle the terminal with a large plyer. It should not move or wiggle, or bee loose..

Thanks Birdman,
I was hoping it would fix itself but that hardly ever happens. #2 battery is brand new and #1 tested well so I think the connections at the starter are the culprit. I have to find a smaller person than me to crawl under there and pull it out, test connections. Hope to do it before Irene blows through!

How big are the battery cables? They may not carry enough to start a cold engine. what weight oil is in the motor. Do your batteries have enough CCA.I would think the warm engine is easier to start because the clearances have opened up and the oil is warm.
