I recently purchased a 1978 Ebbtide Dyna-Trak 160SS fishing boat. It has all options available at that time. It has one feature I am not sure how to use. There is a panel on the bow which contains a socket for the trolling motor, meter for trolling motor battery, courtesy light, 12V outlet, and a three position rocker switch labeled: run & charge ( third position is inbetween these two unlabeled). I think this is used to operate the charging system for trolling motor's battery. Can you tell me how this should be used? Thanks, Bert :D

bertherr <br /> Sorry I can't help with this one. The previous owner installed a nice stainless steel plate with a plug / connector only. (My boat is a 1978 model. Originally it was green. The guy I bought it from painted it white, with real light scattering of blue metal flakes in the paint, and there is a green stripe down the sides.)<br /><br />Gold Bear ;)

Re: Help with trolling motor battery charging.

sorry to reply so late. i have access to 2 dynatrak's, 1982 & 85 models. my 82 wiring was cut/hacked and messed up when i got my boat, so when i rewired most of it, i didn't use that 3 pos rocker. i asked my pop about his, since he bought the 85 new. but he changed the wiring also.<br /><br />i don't have a schematic, but from the info i got on the labels, that switch is horizontal, with (left to right):<br />12/24 run<br />12 run<br />12 x 2 charge<br />he seems to remember that the female plug used to connect the TM (trolling motor) is also used to charge the battery. the cabling up front is separate from the cranking battery cabling, so the TM battery will not discharge the cranking battery (or get charged from motor when running)<br /><br />since my wires to the switch were cut, i pulled it out to run depthfinder cabling thru it. <br /><br />but my best guess would be that the switch was mainly used to switch a 24volt 2 bank battery connection from serial-to-parallel so a common 12v charger could be used to charge them <br /><br />hope that helps a little....<br /><br />PS. if you are running a 12v TM with original cabling, you should be able to ignore the switch. just either put the same male TM plug on charger and charge battery thru the female plug up front or go the ez'r route - lift the lid on battery compartment and clip charger directly to battery.<br /><br />feel free to ask more questions, but you might want to post it under the "boat questions" forum for more responses. ;)

Re: Help with trolling motor battery charging.

Thanks Ebb. I believe you are right on. I emailed Ebbtide through their website and asked about this switch. Here is what they said. We hope you are enjoying your boat. The switch you are referring was<br />designed to switch the batteries between 12 volt output, 24 volt output and<br />charge (top position). In theory, you should be able to put the switch in<br />the top position and charge both trolling batteries with one battery<br />charger. Since it takes longer to charge the batteries this way, most people<br />just put the battery charger directly on the batteries. My switch is mounted horizontal. Bert :D

Re: Help with trolling motor battery charging.

Sounds about right. I have a Stratos but it doesn't have run/charge. Has a 4-blade twist-lock plug.Bass pro sells just the male in red.This is assuming you have 2 positive and 2 negative cables(set for each battery) The positives are jumpered together in the charging plug.So are the negatives.You cut off your jaws on the charger and direct wire the plug to the charger wires.(I used spade connectors on the wires so I could switch back to the jaws)<br />The run charge switch isolates the plug from everything but the batteries so you have no leakage to detract from battery charging but if you don't have at least a 20amp charger, you might as well just put them on the individual batteries. I tried this with a 10amp charger and it took almost 6 hours to charge both,(they had 3/4 of a charge already)I took it off the next time and put it right on the battery and it took about an hour for each.I'm looking for a bigger charger right now.<br /><br />Hope this helps alittle.<br /><br />Tom
