Voltage tester for an Interspan
« on: May 19, 2020, 06:49:40 PM »
Hi
Anyone used Fred's voltage tester on the 12v Interspans.
Got a couple that show a charge light on connecting up to the van battery. The amber no longer shows when I disconnect after the first hours charging. The unit after the second charge is showing the red light on turning on. However lol I'm not sure if the are holding a full charge.
Anyone used Fred's voltage tester.
Loathe to just buy one as I had some units adapted with fly leads for charging with Fred's trickle charger.
That never worked from day one! It just tells me it's fully charged after 5 minutes (or 30's or less)
Thanks Chris
