Charge light flashes continously

What is the name of the manufacturer and model of the equipment you are working on? 

Physio Control AC Power Adapter for Lifepak 12 by Medtronic

Part #: VLP12-06-000102

The charge light on the defib goes on and off with the yellow light on the AC adapter. I hear the relay of some kind in the adapter clicking at the same time.

I've opened some and clean the dust out to repair them and or i've had to replace internal parts. 

it may be easier to replace the power supply if one can be found. 

so many possible issues so maybe a couple of questions might help for background identification:

What do the small bananna plugs look like which connect to the battery(s)?  Are they discolored and have they been replaced lately?

Do both battery indicators blink or only the bay 1 battery indicator?  If just one, have you swapped the batteries to see if follows the battery or the bay?

You say it "clicks" when the battery light blinks, is the click from the defib or the charging unit bolted to the bottom of the defib?

Have you looked in the error code logs to see if any error codes have been loged related to the battery charging operations?

Is the battery actually charged up?  I understand you state the battery on the port is charging while it is blinking??

Can you post some observations of you situation for better troubleshooting?

Hope some of this helps..

1. No plugs involved. Batteries are installed on Lifepak 12. Plug from Physio Control LIFEPAK 12 AC Adapter Power Supply Battery Charger VLP12-06-0000 is in good condition.
2. When I switch batteries the light blinking follows from 1 to 2. If I remove 1 battery it switches to blink on the remaining battery.
3. The click in from the bottom charging unit.
4. There are no error codes related to charging.
5. I truly appreciate any help.

If the batteries are charging with the adapter plugged in then it should be fine,

but if they aren't you should probably find a replacement adapter. Physio-Control no longer provides service for the 12 or its accessories.
