I understand what you mean. I didn’t realize trickle chargers could be a bad idea. I will say I believed it was my best option at the time being that the cold weather was creeping in. Even in the relatively well insulated garage, when the first sign of cold temperatures hit I couldn’t start her up to save my life. It would crank and then click. Which signaled to me that the battery was dead. I wasn’t able to get it started until I went and bought a trickle charger and thus far that’s how I’ve managed to get it up and running now that the temperature has been so low. It likely is going to need a new battery soon though. I don’t keep it hooked up 24/7. Just every now and then to keep the battery going since I haven’t completely finished driving it this year. I’ve noticed the more frequently it’s started up the better it runs. Even if it’s for a couple days out of the week. Used to have a lot of rough idle issues after driving her for the first time, the seller likely hadn’t exercised it as much since it was mostly a show car. When my grandfather and I would drive her around Champaign, Illinois after getting back from Iowa, it would be hard to keep the engine running at times. It wasn’t uncommon for it to idle very fast and rough after starting only to die or stall shortly after. Luckily that hasn’t happened since then. I think we just needed to push all of the mothballs and dust out of the system.
