Hi all, I have this 13.8v DC supply which seems to work fine but neither the volt or amp gauge works. The voltage even when turned off reads 4v and only flickers higher when increased The amp does not move at all. I have measured the output at all of the outlets and they rise and fall with the adjuster.

Any ideas please.

Cheers.

 

Did You try it with a Load ?, the Ammeter will stay at zero without a Load.

Have You tried manually zeroing the Mechanical-Volt-Meter-Needle ?

Sounds like Mechanical-Shock-Damage from possibly being dropped.

Have You searched for a replacement Panel-Meter-Assembly ?

Do You really even need Meters ?

External Meters could be added, if You really like watching them wiggle around.
They could be much larger too.

HI,

Thank you for your help. I have used a load and it works fine as you said. It would be nice to fix the gauges but doesn't really matter as long as it functions. Cheers.

 

I am guessing that the gages are digital, and it seems like there may be a broken connection. So a visual inspection looking for broken connections is in order.
BUT if they are indeed analog displays, the fist thing to do is inspect for the gage glass stopping the pointers from moving.

Hi,
thanks for the reply. Gauges are analog. Free from impediment. Cheers.
