Dagnose a failing Starter?

    Hello, all.

    How do I diagnose a dying starter? My 95 Chevy 5.7 liter just the last few days has been doing the Ruh, Ruh, Ruh, Rinininini start lately. I hope that made sense. I have charged the battery up with a charger to make sure that isn't it. This reminds me of an issue with my 1990 chevy many years past where a similar thing was happening until I was stranded on a Sunday 180 miles from home in front of a dump station on a Sunday with a 29 foot travel trailer attached. <chills up spine...>

    Are there any tests that don't involve removal of the starter? If it comes off it is not going back on. I have had the truck for 10 years of its 17 year life and I have never put a starter on it.

    Thoughts?

    The only test I know of, other than the sound and drag of the motor, is to remove the starter and take it to a parts store to get tested. I would just buy one and try it. If it doesn't fix the problem, which it most likely will, just return it!

    That's what I figured. By the way all, I do know how to spell Diagnose.

    I agree, it is probably the starter; however, I can't rule out the battery yet. Just applying an outside charge is not much of a test for the battery. It should be load tested.

    However, a test you can do in the backyard, just connect a second battery in parallel (jump from a 2nd vehicle). If the 2nd battery started the 2nd vehicle without any drag then we know it should spin a good starter in your truck.

    If the starter still drags, you need a new starter. If the starter spins as it should, you need a new battery.

    I did try and start it with the charger on the 50 amp setting as well; no difference. I will try the jump start trick this weekend, assuming I make it that long!

    50 is just a drop in the bucket, a starter takes a lot more, 2 to 3 hundred, or more. 50 amps is a typical recharge rate for a "low" battery.

    Thanks, RayVoy. Now, I am going to change my story. I put a voltmeter on the battery like I should have in the first place and I am getting 10.67 volts off, 13.48 volts running. I think I may have an unhappy battery.
