Folks with electrical
I am not sure if my questions are specific to the U-Haul battery
charger or chargers in general. When I bought the 13’ U-Haul
from my parents several years ago there was no battery
. The heater and apparently a power monitor / control panel next to the heater were removed and discarded. I installed a deep cycle battery
and the charger / converter seemed to be doing it’s job: charging the battery when hooked to shore power and bypass the battery with 12v power. We took a two-week trip and the system seemed to function properly.
I periodically plug into shore power to charge the battery but I have not been checking for proper function. I am getting ready for a short trip next weekend (after more than a year of actually using the trailer, sad but true) and the charger did not seem to recharge the battery and did not supply 12v power to the lights
With the charger wires disconnected from the battery and turned on, should I be able to measure 12v (or slightly more) from the charger? Turned off I read 0v (no surprise) and on I measure about 4.5v.
By the way, I checked all of the fuses in the charger / converted, none are blown.
The battery did charge up with my car battery charger.
Hoping I don’t need a new charger / converter.
Any thoughts and help are most appreciated.
