My SIMRAD 4G DOME Radar showed an error message when I bought the boat and the previous owner thought that it was a bad RI10 unit, but I eventually got around to fixing it and found out it was an easy fix that I wanted to share with everyone.
After taking it apart I found out it was a bad drive belt. The belts in these things dry rot and fail after a while. Below is a link to where I found the replacement belt and this video shows how to replace it.
REPLACEMENT DRIVE BELT
I ordered 3 sizes in 1/8" diameter and the 21-3/4" circumference fit the best.
