Good day to everybody. Just got my RS warrior a last week ( second one) and having a bit of a problem so here goes.
Question for the Gurus in the forum, What could be making the ECU hot? No fuses are blown, the aftermarket parts ( electrical wise) on the bike are power commander, a second horn on the middle of the bike, aftermarket tailights and rear turn signal ( which I presume are LEDs)I got the warrior as a non runner and was sitting . I tried working on it and realized that the bike was missing a Starting Circuit Relay module so I ordered one.
When that arrived, put it on and tried starting it and i would just crank and when I throttle up a bit it would have this big backfire ( like a cannon).
I noticed that when ever I connected the battery , the ECU get warm and if left long enough, will get HOT to touch especially on the thicker side ( the fat part ). Checked the fuses and connectors for short and I dont see any. I disconnected the battery when sitting.
Yesterday I had a breakthrough, I was able to fire it up when I checked the wiring to the ignition coil were backwards (front coil wire for the rear cylinder). I was able to make it run at first w/o the power commander and after installed the old power command unit with came installed with the bike.
Now I tested it yesterday, the ECU doesn't get HOT when its off ( before it gets hot even when off , just with the battery connected) but after riding around my neighborhood about 5 to 10 mins, the ECU is HOTTTT!
