Check your voltage isnt going above 16V or going below 8v.
do a datalog. youll see it.

it was going about 15 16v -what can be causing this? and what can be done to fix

Your alternator regulator is stuffed or your wiring is incorrect.

Get the alternator tested at auto elec and if its ok wiring is bad.
