TEST DON'T GUESS!

Автокөліктер мен көлік құралдары

In this video we learn the value of taking the time to test a component even when you are SURE you know what is wrong! Although I have over 15 years of experience working on cars and know what a bad starter sounds like I still take the time to prove the failure even though it can sometimes be a pain in the neck to do. We see a perfect example in this video of a poor connection (voltage drop) that makes the vehicle exhibit the classic sound of a bad starter... -Enjoy!

    I went to Ranken Tech in St. Louis, MO. During the drivability/electronic part of the course, I was instructed by a former Marine. He stood about 6'5" and went about 285lbs. Walking up to him and saying "I think......" was akin to a death sentence. He demanded to know what measurements you'd made, what they told you, and your diagnosis based on FACTS. That training has stuck with me all of these years.... Glad to see that you're carrying on the tradition. Kudos!

No rust, no complaining customers, no bills, 5 lifts, no hard schedule...you get the idea. We do lack diag equipment as our OTC scanner broke but it was good for a few years.

    My students and I spent much of last week learning about the importance of looking for voltage drops that appear on a loaded circuit, specifically starting and charging systems.

    Voltage drops are why they went from 6 volts up to 12 volts back in the 1920's and 1930's. With 6 volts you need twice the current for the same amount of power transfer. This makes small resistances at the connections more significant because they will cause higher voltage drops. Older 6 volt cars always had a lot of problems with dim headlights. I heard recently that some auto manufacturers are considering going up to 36 volts. This will reduce the required gauge thickness for all the wires and reduce the significance of connection resistances.

    I'm just a DIYer but I came across a similar situation a couple of years ago on my friend's 2008 Corvette. In this case his starter was toast but it was because the nut on the starter for the hot lead was loose. The high resistance caused the post to overheat and melted the plastic around it until the plastic crumbled and the post/nut fell off when I touched it. It either worked loose or it wasn't tightened properly at the factory.

    I've seen this happen quite often on older chevy and dodge starters, but the bad connection happens on the inside of the solenoid, between the post and copper contact ring. Those solenoids you could take apart and clean the contacts, polish the copper ring, and be back in business. Also, a bad starter will also mimic a bad battery but you can do an amperage draw test on a starter and see if it's out of specification before replacing it.

    The crappy thing about this situation is someone who just assumed they needed a starter and tore it apart and put a new starter in it would have probably fixed the bad connection in the process of installing a new one and they would have thought their parts cannon worked perfectly. Althoygh the customer would have had to buy a new starter in the process and paid for the labor of changing it. The costomer would have had no clue they got ripped off cause the problem would have been gone after replacing the part. Even though they only realy had to clean up the connection.

    Excellent advice! Always test the circuit under load! I've been stung by this twice. First time, wheel loader: electric fuel priming pump not working, pump had power, replaced the pump, didn't fix it. dug further and found the voltage dropped to 2V when you flicked the switch. Turned out to be a broken pin in the connector in the back of the cab. Second time. Wood chipper: Intermittent engine shutdown, No com error codes for engine ECM. Unplugged ecm plug and tested for power grounds and data link continuity, all good so made the call on the ECM. Didn't fix it. Dug a bit further, Supply voltage at the ECM was dropping to 6V when under load. Turned out to be a poor connection at the emergency stop switch which had been wired directly into the ECM power feed.

    Had a similar problem on the 175 amp main fuse connection on my 2007 taurus. It was a intermittent connection at that fuse box by the radiator and if memory serves me right it kept showing up as a low battery. I thinking it was a old battery changed it only to have the problem reappear a week or so later. Used the meter that time and found the voltage drop then cleaned it up. Looked somewhat like your sample. I thought I was smarter than that but shortcut burned me for the price of an un needed battery. Thanks for another good video.
