Welcome to Just Answer!. You have more than just a problem with your electrical system...
....you have a *dangerous* situation...you should have the system looked at by a state licensed electrical contractor right away.
The two readings you gave are not amp readings.... those are typical of volt readings and are way out of balance.
Tell me if the readings were taken from each of the black wires... with one meter test probe on a black, and the other test probe on a white. Or if the 187 reading was taken with a test probe on each of the blacks.
SAFETY ISSUE: If you are working at the meter or the main panel there is virtually no protection at all against your being electrocuted if your hand slips or if you are using a volt meter not rated for use in such locations.You should have this system looked at professionally right away.Phil
yes that was volts in the two phases ( two black wires) and some way there is a wire wich is disconnected (loose)but when i test the black wire with an other black wire wich is connected it give me 120v.
