Kínai energiatakarékos keringetőszivattyúk hibakódjairól tud valaki valamit?
Sziasztok! Több néven gyártják az okosszivattyúkat. GREENPRO RS25/6EA-180 BRH 25-60E/180 Dokumentáció nem nagyon van róluk. Találkozott már valaki olyan doksival, amiben benne vannak a hibakódok? Egy ismerősöm E6-tal küzd, néha megy pár percet neki, aztán megáll. Üdv: Jácinr
Medicor Q125 fűtőszűlak kiváltása

Sziasztok!

Van két ilyen készülékem is, az érdekelne, mivel tudnám helyettesíteni a két fűtőszálat, ugyanis a hőre nem lenne szükségem.

VERTIE: TD8888 Árszorzós mérleg. Nem lehet, csak 2 memóriába beírni adatot.
T. Fórumos Kollégák! Ezzel az új mérleggel kapcsolatban kérdezném, találkozott-e valaki ezzel a típussal? Aki vásárolta, kapott hozzá használati utasítást, de az semmit nem ér. Próbáltam beírni adatokat a memóriába, kettőt lehet, utána fix számok jelennek meg, maradnak is ott. Jó lenne, ha lenne leírás, az alapján valószínűleg megoldódna a probléma, de nem találtam a NET-en ilyet. A segítséget köszönve, üdv.
Battery charger with EM78P41 IC
Working on a speed charge battery maintainer for small engines battery. Heat sink had (2) S2025R T0-220 type components on it. Seems they are an SCR and I have 57 ohms on 1 and 3 pin, so seem they are short. Cant get these anymore but installed S4025R which seems to be better replacement. Before replacing, heat sink seemed to be really hot after replacng on on 
board 10 amp automotive slot type fuse, so seemed these SCR were bad, getting hot woth no load.

Standby LED not lighting with new SCR's installed. Old ones did not have heat sink compound on them, so I used some to better transfer heat. I saw the input of the 7805 1 amp
regulator IC has short, so removed it, and its not shorted, but the feed to it comes from the IC chip on board, a EM78P41 BWD20J. Data sheet for EM78P41 is online. They have pin 16 going to pin 1 of the 7805 regulator. Actual reading on pin 16 to ground is 2.5 ohms. I suspect this IC is shorted output. Is there chance to replace IC or is this repair finished?
