You do not indicate if they checked the alternator, normally the battery receives load from this component when the engine is working.

Hi: First I want to greet you, it's my first contact with you. From Concepciòn Chile, I greet you, the question is as follows: what are the measures if so they are said to reappriev

How, for the head torque I recommend that you visit automecanico.com you will find relevant information, it is a page designed for mechanics I like, and I recommend it health2

Look would have to check first the electrical circuit of the 4x4 indicator, check the Transfer seeks information on the automecanico.com page If there are doubts to tell me health2
