First Time Timing Belt Change F250

Good job of deducing the sequence of events. It cost a few bucks but you can sleep at night now.

Where and how did you measure the 12.2 volts? Just want to be sure that battery is dead ( and if 12.2 after charging, it is dead)

The 12.2 was off the Yamaha gauge. I am pulling the batteries one by one and testing them. I'm trying to revive the bad ones by using a jumper cable to a good one, then putting a charger on the good one. Just following a YouTube video.

How did your Amazon tool work out? I made a tool out of 1-1/2w x 3/8 thick flat stock. Cost $25 in materials.

I did almost the same. A friend had 1/2" bar stock so mine will be heavier. But inertia is not a bad thing.

You shouldn't rely on the Yamaha gauges or any voltage reading from a device like a GPS mapper. They are OK for relative numbers but not for battery testing. In addition, battery voltages should be taken at the battery terminals.

Ya, I pulled all 4 to test. 3 are OK, but the 4th one is suspect. I'm trying to locate a single of the same brand in time for our halibut opener.
