High voltage

[Lead_sled]

Yesterday, my water pump went out. As the warning light came on the dash because of low coolant, my voltage light came on. Do you think it’s because the alternator got wet? Do you think it’ll go away once it completely dries? I changed the water pump today and drive down the highway and voltage would spike up to 16. I haven’t had any prior issues with voltage. With the truck turned off, an electronic meter shows the truck to be at 13.0 volts.

On a side note. I posted awhile back about my low fuel mileage. Since the truck was down, I removed the cac to have it checked. Wow, poor thing was beyond repair. Purchased a new one and installed. Just the few miles driven down the road, the truck is stronger and my wrong fuel economy meter shot up.
