im having a lil problem with my schwinn s500 had not much use but I tried plugging in my charger to my batt. Note my charger is a Jing Cheng 24v charger has 2 LED indicator (FULL) which is Green and (RUN) which is RED. Now the problem is that as soon as I plug in my charger the green FULL led indicator stays solid I DO NOT get a RED (run) light at all. So I disconnected it and check the output voltage from the charger and im getting about 27.5v now i got to my battery its about 23.4v Im dont know whats going on here im assuming that I have a faulty charger can it be something else?? Id just hate to buy a battery charger if need not be. Do you guys know what voltage should come out of a charger? Can a bad controller affect the charging process? I did check all connections for possible weak points ect. PLEASE ADVISE!! Thanks!!
