I’ve been the proud owner of a dual Raptor for about four months. I’ve had no issues with it…until about a week ago, then began a sequence of events that has me fearing its fried. To best explain let me start with a quick chronology:
1.) June 26th - board randomly shuts down while riding over rough surface. Turn off/on, board fires back up, no issues rest of day.
2.) June 27th - while riding the board shuts down and won’t turn back on. Power switch on space cell is very loose. Upon further investigation, it appears the battery shifted which jammed the power switch against the opening in enclosure lid causing it loosen and fail.
3.) June 30th - thinking this would be a relatively easy fix, I order new power switch (this one http://www.ebay.com/itm/5Pcs-2-Pin-On-Off-SPST-Round-Rocker-Switch-AC-10A-125V-6A-250V-Black-/262209348826?_trksid=p2141725.m3641.l6368 ) and remove old switch and solder (I suck at soldering) in the new one. The new switch is virtually identical to old, but the prongs are a bit longer. I snip the prongs shorter so it lays flush on space cell like the old switch. Switch works, board powers up and seems fine. Only difference is the lcd screen blinks once when switched on. Test ride around block is good to go, no issues.
4.) July 3rd -
A) riding board to breakfast, take off from stoplight with a kick push then throttle like normal, accelerate to about 15mph and suddenly the brakes (or brake) slams on, I do a poor superman imitation and earn some minor road rash. Get up, look at the board, it’s off and won’t turn back on. One motor seems to have heavy resistance (attached to slave VESC) while the other has normal rolling resistance.
B) Walk home, pull space cell out and disconnect from board, turn on and it powers up like normal, plug back into board and it shuts off. Happens multiple times. Plug fast charger into space cell while battery is connected to board and get a decent size spark.
C) decide to try different battery. Plug in @torqueboards 12s battery (used with board before without problem) get a fairly big spark at xt60 connectors.
D) pulled new space cell switch. Soldering is ugly, but seems solid. decide to seek help before I melt my board.
Am I correct to assume there is a short somewhere in board and not battery?
Could poor soldering in power switch to battery lead to a short in board?
Are my VESCs likely fried?
Would a short in one of the motors cause this?
Greatly appreciate any feedback.
