    Corrosion on TM receptacle

Hereís the deal, Iím having some serious corrosion issues with my TM receptacle. Cleaning it and using some dielectric grease is the plan, but Iím trying to figure out the cause.

If I cleaned it off today and didnít put anything on it, it would be just as bad, if not worse in two weeks. I let the boat set for three weeks over the winter and the corrosion completely disintegrated one of the pins. I have never seen this happen so fast before, something is not right somewhere.

I installed a new one this spring and left the batteries unhooked. Since itís been in weekly use, I have to check it and add grease every few weeks.

Iím thinking something is just not right somewhere. Otherwise, the batteries or strong and no TM issues at all.

   Probably electrolysis. Do you have a TM battery disconnect? from Wackoman  7/23/2012 4:01:41 PM

If so use it.

Bought it last weekend. Just thought there might be an underlying issue with the wiring, not obvious in any other way.

 I would guess the TM stays plugged in and it's drawing a little current. I would replace both connectors, coat with dielectric and install the cut off switch.

 Unplug the trolling motor power cord from the boat receptable when you are not using the trolling motor.

That sort of acts like a cut-off switch.

My Motor Guide Tour motors use current when not operating due to the elecronic circuit. I unplug it as soon as I get off the water. The motor doesn't drain my batteries between trips if I unplug the charger.

  Both Motor Guide and Minn Kota recommend you disconnect the trolling motor while charging as both of them now have a circuit board that is powered even when the motor is not being used.

Especially when you are charging the TM batteries.

   Electrical Service from fishsmart #10374 #10374  7/24/2012 10:25:46 AM
  Cutoff all electrical service when the boat is not being used unless you need the power for a bilge pump to keep the boat from sinking.

If you leave the power on, the wiring will fail much sooner.

   technically from MikeF  7/25/2012 1:54:05 PM
 Technically the automatic side of the bilge pump should be wired directly to the battery with only a fuse (or breaker) in the system. You should never be able to turn the power off to your bilge pump even on a trailered boat.
