Is there an easy fix for the issue I am having with my P3A Controller. When plugged in LED lights flash in sequence. After it appears to be charged controller won't turn on, nothing happens. i tried disconnecting the battery to no avail.

I last flew about 2 months ago and everything worked fine. i did however the first time I charged, connected both the battery and controller. It worked that day but now won't turn on, has not been powered up again for 2 months. It has been stored in the case i have for it.

Any assistance would be great,

Controller GL300B

Good morning and WELCOME to the forum Gary.

I moved your post to it's own thread so it's no longer buried within another thread. This way you should get some help on your specific problem(s).

Looks like power control circuit failure?
Some people reported rebailing the power control chip fixed such issue.
You'll have to search old threads for details.

Also, make sure the battery is really charged (ie with multimeter - charged has 4.2V per cell), and isn't puffed (when hydrogen bloats the battery, it destroys its structure, making the voltage drop unpredictably; such battery cannot be safely repaired).
