Model JAC0524R/3 Output: 24VDC 5A It's used for two sump pump batteries 24/7. It has a fan (for some unknown reason). Recently, it has emitted a whining sound which can be corrected by shaking or turning the charger, or even blowing into the chamber which houses the fan. However, the noise invariably returns and requires a repeat performance to silence it. Is this whine a symptom of serious trouble or danger, or just some harmless debris? The email contacts at Schauer's web site don't respond and I haven't been able to get anyone but receptionists at the waterproofing co. Please cross-post any responses to balt.general. Thank You, Jack

The fan is there to dissipate heat from the 140 watt power supply The whine is the fan bearing going out. Replace the fan and everything should be cool.

When the fan does go out, what are the ramifications? Ineffective charge? Danger of fire?

When the fan goes out it may overheat and either shut down or break down. It might not do either. Best regards mark BroJack wrote: > On Thu, 30 Dec 2004 08:50:40 -0700, "Mark W.
