Not done much to Flint that last few weeks, luckily I sorted his coolant out months ago as its now -30 outside.
Flint does have an engine block Defa heater, which I have yet to use due to not having the correct lead, or an extension long enough to run from our first floor apartment balcony down to his socket. We are on the waiting list for a parking space with plug in, but the list is long, and could take a couple of years or so before we are allocated one.
So what I plan to do today, seeing as I have now fully recharged his battery, (Purchased the charger below, which is just like the Lidl trickle charger many members here have purchased) although its the wrong type ah battery, i do have a good 80ah battery coming tomorrow (Was sold out today), is to plug in his engine heater for a few hours, then fit fully charged battery, then attempt to start him up for the first time in what seems like ages.
I had been given another battery, but not only was it too tall, after charging it for five days, I discovered its dead anyhow.
I also invested in a multimeter to help aid my up and coming electrical upgrade/install.
So fingers crossed, the engine heater will do its magic today, and if it does, i will invest in a timer, and cabin heater for the Defa system too
