I bet a quickie, at-home fix after he discovered that Home Depot and Ace no longer stock the ANL current limiters.
They seem to have become a mail order only item, different from a decade ago and earlier when a lot of the flying RVs were built. At that time Home Depot had many sizes in stock.
In Tucson recently I could only find 100A ones and that was in an auto custom sound shop.
Maybe it's time for us to standardize on a more up-to-date high current fuse?
