mames19 Posted June 8, 2011 Posted June 8, 2011 so i had my trolling motor checked over everything worked fine. hooked it back up to the boat, the leads into the trolling motor show 25.5 volts, when you pushed the button the motor doesnt spin and it drops to 2 volts, then goes right back to 25 when you let off, is this the batteries?

mames19 Posted June 9, 2011 Author Posted June 9, 2011 even if when i dmm the batteries they hold at 12.5 a piece? while the motor is on Quote
CODbasser Posted June 9, 2011 Posted June 9, 2011 even if when i dmm the batteries they hold at 12.5 a piece? while the motor is on where exactly are the leads you are testing voltage on? Quote
mames19 Posted June 9, 2011 Author Posted June 9, 2011 it has a plug into the boat, i replaced that, i have the cap off the plug and im testing it right after the plug-in on the trolling motor side Quote
CODbasser Posted June 9, 2011 Posted June 9, 2011 do you have any batteries you can swap in to test with? or maybe borrow a friends for 5 minutes? how was the motor tested? Quote
mames19 Posted June 9, 2011 Author Posted June 9, 2011 the motor was testes in a test tank at the local minn kota service center, they powered it with there power supply Quote
mames19 Posted June 9, 2011 Author Posted June 9, 2011 swapped in batteries i had layin around, and it worked, any thought on good batteries? cabelas? Quote
Super User slonezp Posted June 9, 2011 Super User Posted June 9, 2011 I'm on year 3 with Cabelas deep cycle batteries with no issues. I think they ran about 80 bucks a piece Quote
CFFF 1.5 Posted June 9, 2011 Posted June 9, 2011 I have been running the Wal Mart Maxx Marine batteries for years and they seem to last a pretty long time. Quote

gar-tracker Posted June 17, 2011 Posted June 17, 2011 If you fish a lot and get 2 -3 years out of trolling motor batteries you v done good. Quote
Super User Jig Man Posted June 17, 2011 Super User Posted June 17, 2011 Before I bought any Wal-Mart deep cycles I'd check the warranty. Some stores have discontinued the warranty on them. Quote
Ann-Marie Posted June 19, 2011 Posted June 19, 2011 BEFORE you buy new batteries, put the old ones back and test again. If you had a bad battery connection it would give the same symptoms and just substituting batteries may have cleaned up the connection. Quote
Super User Way2slow Posted June 19, 2011 Super User Posted June 19, 2011 I'm sorry, but before I bought new batteries, I would make sure that's the problem. My magic wand is not working right now so just because it's dropping to 2 volts, doesn't mean crap about the batteries being bad until you check them. Dropping that much, would come closer to be a bad cable/connection. Connect your voltmeter across the lead post on each battery and see if the voltage drops there. Fully charged, they should have 12.6 - 12.8VDC. If they are holding voltage when you run the TM, batteries are not your problem. To locate the problem, first connect the voltmeter on the negative lead post of battery one (not to the cable)and the postive lead post of battery two and run the TM. If the batteries a still holding their 24+ volts, that means the cable/cables between the two batteries are good, if the voltage drops, it has a bad/dirty end on it. If the check across both batteries is good, move the negative lead off the lead post and connect it to the negative cable, try TM again, if it holds voltage, that negative cables connection/connector is good. If it drops, it's bad. Now move the move the voltmeters positive lead from the lead post to the TM's positive cable and try TM again, if you loose voltage, that positive cables connection/connector is bad. Quote
