Device without install harness drains battery and disconnects

Written By Vishal Singh

A device installed without its proper wiring harness, relying on its internal battery instead, can experience recurring low-battery-triggered drops and disconnects.

This is a fringe case — most installs use the proper harness — but when it happens, it needs to be reported to Geotab rather than resolved locally.

What to gather before contacting Geotab

  • Full vehicle information (make, model, year).

  • Whether the device is interfering with anything else on the vehicle, such as the ECM.

  • Whether the issue has been happening consistently since install, or is new.

  • Results of testing: does the problem follow the device if it's moved to another truck?

Report this to Geotab with the above details — they're equipped to diagnose whether it's a harness, battery, or device issue from there. There currently isn't a self-service fix for this scenario.
