Frying chicken wings all the way through I have tried deep frying chicken wings few times. 
The first time I tried it, the oil was heated a lot and I continued Frying it until it was crisp outside,but when ate it, it was not cooked all the way through, it was pink and the joints of the wings still had blood. 
Second time, because I thought it was because I cooked the wings on high heat, it was burned on the outside but still not cooked inside, I tried Frying the wings in low heat, but the result was the same, undercooked bloody joints in the wings and burned skin. 
So how do I deep fry the chicken wings so that it is cooked all the way through? 
Do I boil it in water before i deep fry?
It sounds like your temperature is way too hot. You need a thermometer as there's no reliable way to tell the temperature of your oil without one. A simple method is 190C for 10-15 minutes depending on the size of the wings, that's from refrigerator temperature.
