Again, Bosch charger repair. 36V (14.40-36V), 8A unit. Very similar to GAL 1880 CV that you can already find on this site.
Same issues as its smaller sibling (GAL 1880 CV), failing the primary side.
Most common components to give up:
As a replacement for Q1 STQ1NK80ZR-AP (datasheet),I mostly use:
HFU1N80, 800V, 1A in I-PAK case (datasheet)
BXP2N65U, 650V, 2A in TO-251L case (datasheet)
Here are some High Resolution pictures of PCB:
p.s. pictures are not very nice because I had to remove a thick protective epoxy layer from PCB.
And in the end, as always Complete component list: GAL3680CV Component List
Hope it helps. Enjoy.
I can see why you love these electronics so much. I love looking at images of them. Try more here https://www.appliancerepairvictoria.com/gallery.html
Great images. Keep up the good work.
Haben sie einen Schaltplan? Meine Ladegerät ist komplett tot, der R13 war kaputt, ist getauscht, immer nocht tot.
Sind Sie an einer Bauteilübersicht interessier? Habe eine erstellt.
Gibt es ein Servicemanual für dieses Ladegerät?
Ihre Webseit ist super!
Danke Gruß
Vocês tem o esquema eletrônico da placa GAL 3680 CV?
A explicação sobre a placa gal3680 CV muito bom.
Desde já agradeço.
I’m sorry but I don’t have the schematics. If I did I wouldn’t waste my time measuring and documenting component by component.
