Hello everyone!
I have this SBC 500 FR Advanced plus nautical charger that gives E1 error which, in manual, is stated as output short error.
Examining the rectifiers i noticed that they measured about 150k resistance backwards so i thought they were leaky and replaced them.
However i still get the same message
I removed the main transformer and still get the same message.
The parts i replaced are:
1x STPS30H100CW
1x STPS40H100CW (these two are interconnected)
3x STPS6045CW
On the main input filter capacitor i get 315V when i switch on the charger, then when a relay engages i get 390V, and again when the error is detected and the relay disengages i get again 315V.
Now i am skeptical if the problem is indeed on the output or it is a false error.
Any input greatly appreciated!
Thank you!
