What is your question?
I have changed the Battery, Alternator, Voltage regulator , cables , I check the fuses and the relays still no luck . please help if . it's a Toyota 1984 pick up .
The most important thing is the proper voltage and grounding at the alternator-You need to have it checked and the problem will be solved-take it to a shop for this diagnosis and you will save money.
