Throttle and Battery Issues After Controller Replacaement

[emarine]

Recently, the throttle stopped working while others look normal, so I contacted customer service and replaced the controller myself.


Immediately after the replacement, the throttle seemed to work for a few seconds, but soon the battery level dropped back to one bar and stopped functioning.

The power turned off, and when I tried to turn it back on, I heard a small spark-like sound coming from the battery about once or twice per second while the battery level on the left controller dropped to 1 and blinking. So for now, I've disconnected and removed the battery. Anyone experienced similar issues?

Haven't experienced quite the same thing, but I did experience a battery drop after a controller change. It turned out that a contact pin in the plug to the display was bent, and was next to the plug of the battery. After pushing back a little bit this pin, the connection was good again and the battery level was also back at position at maximum.
