In this video I repair a dead odometer on a Buick century. it is common for these to break when the MELF package resistors fall off the board. I always replace these with 150 ohm 3/4 watt resistors. Do not use THT film resistors it doesn’t look professional. You can reflow the old resistors if they didn’t all fall off the board but be aware it’s going to take a lot of flux to reflow them. The solder faces on these MELF resistors are normally super corroded from heat.

On a Buick roll this week. I was hoping I was going to get to program the Odometer to do a video on it but the mechanic does that in house I guess.
If you want to get technical, these clusters actually have two 120 ohm and two 150 ohm resistors. But four 150 ohm resistors will work fine.
Back in the good old days people "repaired" high-mileage cars with a reversible drill hooked up to the speedo cable. In 10 minutes you now had a low-mileage creampuff…
