Okay guys before we begin let me first say that I am not the most electrically inclined person there is. My problem is with my 07 Puma that is equipped with a Cul Em Rite Pro Pac IV charger. Recently I had one battery( Trojan) that I continuesly had to keep adding water to, eventually I had to replace it with a new one (Trojan). Now I think my charger is not working, heres why. I keep the charger plugged in all the time in between trips, and yesterday after 5 hours of fishing in calm conditions I had nearly no juice left. I put the boat away and plugged the charger in and after about 2 hours it showed all green lites. This morning it shows all “green lites” still. So I took a portable charger and hooked it up to one of the batteries and it shows a yellow lite which means its charging. So obviously the batteries are NOT charged. Question; How can I check the charger to be sure its actually working? Remember, not electrically inclined!! Also is there anything else I should look for? Thanks, Keith
