|  Wet servo reversing Y-harness!
Long story short, crawling in the dry riverbed, flipped the truck down a boulder and landed it in a pool of stagnant water. 4WS, the servo reversing Y-harness's box thingy (Futaba SR-10 Synchronized Servo Reverser, if that matters) was mounted on the rear steering servo, and was about the only thing to really get wet. The rear servo immediately jammed way hard left (front is still under control) and sat there kind of shivering. Other than the coulda/shoulda/wouldas (believe me, I've been through them all) is there any hope for saving the harness? I'm going to let it dry out for a week or so before I plug it back in, if it's still not working properly, is there anything to do other than be more careful next time? Thanks in advance -val |

I think probably the best thing to do is waterproof it. As in use a marine silicone and seal up the cases and any openings, u could also put it in a baloon and rubberband the end. Hope this helps! Water Proofing Electronics Alos that thread is about waterproofing the elctronics. |

Typically if it didn't fry, water woln't cause problems, there maybe a chance that if you let it dry it will start working again. I dumped water on my keyboard at work, and after it dried Everything worked a-ok. |

Hair drier & wd40 (ya know wd40 (water dispersing #40) was invented to dry electrical parts?).  |

Let it dry. Then get some liquid electrical tape and coat every seam and opening around it. I use this stuff on all my electronics to protect them from water and arc-ing/ debri damage.

id let it dry out for a while, a good trick is to open it up and stick it in a sealed container with rice. the rice will pull the moisture out. after that, hook it up and see if it still works. if everything is good id coat the circuit board with a conformal coating, this will prevent moisture from getting to the board effectively making it water proof.

x2 ! Just spray it down with WD-40 and pat it dry shake it a little spray again . Let stand for a day or so (if you have desk fan use it) . If you use the hair dryer set the heat on very low !!! It should work fine unless it fried . Read the sticky on water proofing electronics . It will save you in the future . I use a plastic hobby box sealed with silicone for the Rx and esc and use the o ring trick with grease on the servo . | |
