Battery Draining on Tender
Very new here and looking for some help. I purchased a 40 f-1 about a year ago and since have been getting work done. (12v conversion, new ignition, new gauges, new starter, new gas tank, new wiring harness)
I have had the truck on a tender in the garage but when it sits for more than a handful of days she doesn’t want to start right up. Been giving it a little gas to get some in the lines which seems to be working.
I am by no means mechanically sound especially on a 40 flathead so little lost. These old engines just need a bit of gas in the lines to fire up, or should I be assuming that something is draining her?
Any ideas/suggestions would be great. After I figure this out it’s time for new seats
