Batteries are probably weak, plug block heater in for at least 4 hours so it is not as hard to turn over. Crank engine longer in colder weather.
I have already had to replace my starting batteries in my 21, the 19 is probably on borrowed time.
Good replacement, Duracell at Sam's, Group 31 model C with studs, made by East Penn, best price, nationwide guarantee.
