Check the battery cable connections. The ring terminals on the end of my battery cables weren't crimped correctly and thus had a voltage drop. If your battery tester has a digital voltmeter, I would suggest checking the voltage at the input and output of the battery switch. Most likely it is a bad cable or switch.

Hi List
I have a quick question. My boat starts on the the #2 battery, but will not start if I put it on the #1 battery (It slow cranks, like the battery is dead). It will also start if I use both batteries. Both Batteries are fairly new (both Sears Marine batteries, changed two years ago). Both batteris are reading good and charged on my digital battery tester. Someone suggested that I may have a bad connection on the #1 battery. My question, is : How many points must be checked starting at the battery working to the engine? Thanks.... Andy
