Hi all, i done a search but didn't come up with anything that relates to my problem.(if their is please point me in that direction)
Please be patient, im not the best at electrical currents and thing, so anything i leave out please ask and i can find out or give pictures if needed.
So i will try to keep this short, but give as much detail as i can.
I borrowed a charger to try and start my van, the battery was still in vehicle, its a heavy duty upright charger. (sorry no name or info on the outside.
The charger has 4 settings 12v normal, 12v boost, 24v normal and 24v boost, i first connected it and put it on 12v normal, for about 25 mins, was reading about 14-15 amps on the needle tried the van and still dead, i was told to give it a boost for a few minutes which i done, out put of about 35 amps (again by needle dial on charger) to no avail.
Well after the next try i took all connections off battery, cleaned and checked and then re-connected, connected charger and tried again on boost, this time the charger made a clicking noise and the needle dropped to the bottom, with no movement.
I unplugged the charger, checked for any problems or burning smell, all seemed o.k, went to re-connect and their was a big spark from the + terminal.
Now this confused me as the charger was unplugged, i tried again and the same thing happened.
I assumed the battery was just beyond or maybe shorted or something, so i tried the charger on my good car battery, still the same, sparks and no needle movement.
I took the car battery out and tried again, still sparks with battery out and charger un-plugged, no needle movement, i also tried on an un-charged battery aswell, still the same thing happens.
So can anyone please help me repair this charger, if you need any more info please ask and i will do my best to get it for you.
i can provide pics if needed. i have taken it apart and looked for anything out of the ordinary.loose wires, burning smells, broken wires and everything looks normal.
Please please help
thanks wayne
