Increased resistance indicates a poor joint or corrosion has taken place in that winding.

Check again with another meter.

Depending on the design of the coil this can be an easy fix, like an external break or failed solder joint but corrosion of the winding is another matter.

I do not know what this coil looks like, but, if it is a two layer solenoid that is good. It can be rewound as long as the same wire size and replacement of the celluloid liner with PETE if it is a coil on top of a coil.

It takes patience and method, a finished rewound solenoid coil can drop in and work like it never happened.
