Battery Selector Switch? Not sure....

[jheard]

Hello all. I need some expertise. I have a 2002 Century 2100 with a 2002 Yamaha 150 2-stroke. A couple weeks ago I took both batteries out and took them to get charged. I reinstalled them and now things aren't working correctly.

When switched to battery 1, all the electrical switches will work ie. trim tabs, nav lights, depth finder, etc but the radio won't come on and the motor won' t raise or lower.

Whenswitched to both batteries, everything works like it should.

Whenswitched to battery 2, nothing electronic will work but the motor will raiseand lower.

I triedreplacing the switch but it does the same thing even with a new switch. Ichecked all the fuses I could see and they were all good. I'm pretty sure I putthe correct lead back to the correct battery, but if I had gotten the leadsmixed up could that be a cause?

Any ideasare appreciated. Thanks.

the first thing i would trouble shoot is why the motor wont lower and raise on battery one...use some logic and just dont start swapping wires...the two large wires coming from the motor must be connected to their respective posts on the battery in both switch positions...use the same approach on every device that it not working...keep it simple..one thing at a time...

just curious about why you removed batteries for charging?...if you store the boat where you can use a charger then they should be fully charged before you put the boat in the water every time...
