My Volare hates it when the temperature get's below 25, and as I found out this morning if it sits in single digits for too long it will not start. Even though it's the correct battery and the alternator is good there's not enough cranking amps to turn it over. Even with ether assist. Happened at work and someone gave me a jump, but even after it got running, after a few seconds it'd die. Took 6 tries to get it to stay running. I'm going to have to invest in a heater of some type (not one that requires knocking out the freeze plug). I was thinking of a tank style like a KAT one, but how many watts would it need to be? And will it even work with the car?
