Hi there! Well, the other day

Hi there! Well, the other day it dropped down to -20F, and we had a starter problem. The starter hsd been working fine in cold temperatures and did so last year. However, this time, the starter would not disengage once the engine fired, making expensive grinding noises. It was shut off after three short duration tries, and now that the temperature has risen to +30F, it seems ok. To prevent this from occurring when (not if, when) the weather again deteriorates, what should be done? Years ago, more tradional machines would replace the solenoid. Stil hold true? Thank you, Dan Hudson
