1994 Mazda B2300 Q&A

1994 Mazda B2300 Question: When I turn the key on I have no power, it builds and starts. What do I check.

When I first turn on the key on my 1994 Mazda B2300 I have no power. The charge slowly builds to virtually full in about 30 seconds. Once running the voltage meter bounces considerably, but the truck runs without any problems( Until I shut it of and all power is lost immediately.) Do you know where I should start in checking things out? -
Answer 1
I would suggest you begin by checking the battery and its connections. The battery should be load tested and be sure the connections are clean and tight. -

Thank you Jim, I was able to test the battery which was giving off a widely fluctuating charge. I appreciate your help. -
