I have been running this off the 12v charge in my Grand Cherokee and, more recently off my 80w solar panel on my Patrol. I ca get 18 volts showing at the solar but only 1.2 (at best) at the charger. It appears that something may have failed in the charger itself. The battery will charge on 240v. Can you offer any advice on how to remedy this situation? Many thanks Greg
the DC to DC car charger needs a constant 120 watts to operate to spec, the DC to DC car charger is not meant to be plugged into a solar panel of any size the reason is the voltage fluctuation is to much and not a constant 120 watts this is a problem and the DC to DC car charge is only meant to be plugged into a female cig socket that is connected to a car 12 volt system.
so i am 100% clear your saying the Ark Pak will not charge via the supplied DC to Dc car charger is that what you are saying ?
if so please check the 10 amp glass fuse that is located on the inside of the male socket and check that is has not blown, if you mean something different could please explain so i can offer some advice.
Thank you for the reply and i do understand why you have done it, what i must advise is at ark we do not encourage or recomend this course of action, but i do understand why you have done it.
I have some questions for you to help understand the problem.
the new lead you have created does it have a fuse on it and if so what size ?
the reason i ask is that DC- lead came with a 10amp fast blow fuse and the wiring is 16AWG wiring which handles a max current of 13 amps by cutting off the DC male socket and if you have not put a 10amp you may have fatigued or shorted out the wiring by allowing too much current to pass thru.
