Default Re: Columbia 48V Car Issue

Here’s another check. I’ve seen connections where the main harness plugs into the controller be intermittent. Have had a few where we unplug the harness, clean both sides with electronic cleaner then plug back in but actually use some zip ties to make sure that harness stays fully seated. Cheaper than replacing the harness. Not the preferred repair but for diagnosing it helps narrow the possibilities down.
