You are about as far away as I am, in any event you need workable batteries of some sort in the car to test the charger, the charger (if your car is a 72v car) should charge the batteries up to between 84-90 volts NOT 72 volts which is your nominal, Those miles batteries when new sit around 13.3 volts without the charger running when fully charged. Anyway the charge should climb up to 84-90v depending on the temperature then sit there a long time then drop down to the float mode then the charger shuts off, Miles has used different types of chargers so it may vary a bit but not by much
Something else you should check is ARE all the batteries at the same voltage before you charge?
If one is way low and the others are way high you can blow out batteries since the charger will drive them up over 18 volts ea if you have one that isn't coming up correct, so take care.
Good Luck
