Hello,
I need help diagnosing and repairing my metal detector device, model Garrett ACE 250. I accidentally powered it with 8 V lithium batteries, and now the device is not functioning properly.
Details:
- Device: Garrett ACE 250 metal detector
- Power input: 8 V from lithium batteries
- Issue: After connecting the batteries, the device stopped working. No display or response.
- What I tried: Checked battery polarity and connections. No visible damage, but unsure if internal components were affected.
Important note:
Electronic components are not available in my local market, so I’m looking for repair solutions that do not require replacing parts. I’m hoping to identify the faulty section and possibly repair it using existing components or alternative methods.
I've attached several images showing the board and components. Any advice on how to test the board or pinpoint the issue would be greatly appreciated.
Thanks in advance!
AI: After applying the 8V lithium batteries, did the device show any signs of life at all—such as sounds, lights, or even a brief display flash—or is it completely unresponsive in every way?
When I power on the Garrett ACE 250, there are absolutely no signs of life. The screen stays completely off, there are no sounds, no lights, and no noticeable heat from any components. It behaves as if it's completely dead.
I’m not sure if any internal protection was triggered or if something got damaged due to the 8 V input.
Let me know what I should check first.
AI: What is the original/standard battery voltage and type for the Garrett ACE 250, and have you tried powering the device again with the correct batteries after the incident? If so, did anything change?
Yes, I did try powering the Garrett ACE 250 again using standard AA alkaline batteries after the incident. Unfortunately, the device still shows no signs of life—no display, no sound, and no response at all.
The original battery specification for the ACE 250 is 4 AA batteries (6 V total), typically alkaline type. I made sure the polarity and connections were correct during the test.
If you have suggestions for where to begin diagnostics on the board, I’m ready to take measurements and share results. I’m working with limited tools and no access to replacement components, so I’m hoping to repair it using only what’s available.
