Looks Correct, But is it?

Here’s a great case study, provided by our friend Michael in Utah, related to a 2010 Dodge Ram 1500 SLT that his customer brought to him for a TIPM reset. As expected from Michael, he dug into the problem vehicle prior to performing the TIPM reset and really didn’t like what he saw, which included no comms with the vehicle’s ABS system (the reason the customer installed a replacement TIPM in the first place). That sent him down a diagnostic rabbit hole. After doing his homework (wiring diagram review, understanding system function, etc.), he found reference voltage somewhere he wasn’t expecting to find it. This lead further down the hole, but also to the root cause of the problem, which eliminated the need for the replacement TIPM. Check out the case study to get the full story. It’s a good one.

Peak Amps – Don’t Tell the Whole Story

It was great to see so many of our technician friends at the recent Vision Show in Kansas City (of course, we love it when a show is right in our backyard, which almost never happens). We had many great conversations at the show around starting, charging and maintaining batteries. One of the most common topics we got into was Peak Amps. Those conversations were so common and so in depth that we thought we’d share our thoughts on the topic here. Peak Amps – One Power Value, But Not the Whole Story Peak Amps are a great starting point when it comes to assessing if a jump starter is capable of meeting your needs. After all, each user’s needs are different when it comes to a jump starter – are you purchasing one to help you avoid a potential hassle of a future dead battery as vehicle owner or are you purchasing one because you run a roadside recovery business where you could perform 8-12 jump starts per day for your customers? Peak Amps is loosely defined as the total potential current available from a specific jump starter, i.e. if you shorted the clamps, etc. (which we do not

JNC1224 Tackles it All!

“I work setting up and supervising the removal of everything after large corporate auctions. There have been times where we have done construction or oil industry or trucking company auctions with 10’s or even 100’s of pieces of heavy equipment or semi-trucks, etc., being sold. At an auction 7 years ago, I bought a Clore Jump-N-Carry JNC1224. I’ve used it many times since then and it has amazed myself and many others with its ability to start just about anything, anytime. 12 volt or 24 Volt – it doesn’t matter. The cold cracking amps have never failed to start any piece of equipment or vehicle at any temperature. I’ve jump started over 20 semi-tractors in one day with it, all with dead batteries from sitting idle for months in below freezing weather, without recharging the JNC1224 that day. It’s a beast! I’m not sure how it is but it appears to be as good as new and still functions beautifully! I recommend Clore products for any and all of your jump starting needs!” BillSouth Elgin, IL 3400 Peak Amps – 12V 850 Cranking Amps – 12V 1700 Peak Amps – 24V 425 Cranking Amps – 24V 46″ #2 AWG welding

AGM Batteries – An Update for 2026

Over the years, we have written quite a bit about AGM batteries. That’s for several reasons: 1.) AGM batteries often require different service routines than traditional flooded lead acid batteries, especially when it comes to testing and charging, two topics that are near and dear to our hearts; 2.) there is quite a bit of confusion and misinformation out there related to this battery type, which we try to do our part to set straight; and 3.) AGM batteries have seen rapid growth in the North American car parc in the past 10-15 years, which means that our audience is encountering these batteries more and more, whether they’re a professional technician or a vehicle owner. To provide a sense of just how AGM batteries are growing in popularity, here’s a quick excerpt from US AGM Batteries for Car Market, a December 2025 research report from Emergen Research. “The growing prevalence of start-stop systems in modern vehicles is a primary driver of the AGM battery market… According to the US Department of Transportation, the adoption of start-stop technology has increased by over 30% in new vehicles since 2020. This trend is expected to continue, with manufacturers increasingly incorporating AGM batteries to

OE-Specified Voltage Environment for Reprogramming 2026 Edition

When it comes to vehicle reprogramming, there is one constant, and that is the need for a stable voltage environment to ensure a successful reprogramming event. No matter what your reprogramming tool of choice is, be it OE tool, aftermarket tool or pass-through device, each OE has a recommended target system voltage in which the event should take place. Not surprisingly, they tend to vary from make to make, and even can vary from model to model within one manufacturer. Below is an updated table of OE-specified voltage environments for module reprogramming, developed and updated in partnership with our colleague Tanner Brandt, Diagnostic Technician, Technical Trainer, and Founder of Auto Diag Clinic. Where there is additional detail beyond the general spec, we have added it in the Comment column below. We hope this is helpful as you tackle your programming tasks. Our PL6100 and PL6850 are excellent units that create an optimized electrical environment for module reprogramming, with super clean power delivery (<100mV of ripple) and operator’s controlled output, from 13.1-14.9V.

Foiled by a Missing Option?

Here’s a pretty strange and frustrating case study, provided by Chad in Colorado, related to a 2020 Toyota Avalon that, upon turning the vehicle off and exiting it, the infotainment cluster remained on and displayed a “key left vehicle” error message. He started his diagnostic process, scanning for DTCs and testing the vehicle’s can bus network, which revealed that numerous modules remained on after vehicle shutdown. He then followed a logical diagnostic process to eliminate potential causes and work his way to the root cause. The funny thing is that the source of the problem was an option the vehicle wasn’t even equipped with. Check out the case study to get the full story.

Years of JNC660 Happiness!

“I have had a JNC660 for at least 20 years. I’m on my third one. I follow the instructions for proper care and it stays plugged in, unplugging it every so often. I use it, then plug it back in – the durability is extremely mind-boggling. I carry the JNC660 wherever I go. Last year, my daughter was playing a collegiate game three hours from home. My wife and I stayed behind and helped out until the team bus left. As we walked an eighth of a mile at 10:30 on a cold November night to where the parking lot was, we noticed two cars with their hoods up. One car was trying to jump start the other. Something happened and now both cars had dead batteries. My wife and I approached them and they said that they had called AAA, but there was a 2 to 3 hour wait. I told them that I could help them out. I went to our SUV and pulled out the JNC660 that was in the trunk. I jump started one vehicle and then jump started the other. The date code on one of the batteries was eight years old. The other vehicle

In Extreme Cold, Jump Starters Beat Booster Cables Even More

Many years ago, we published an article about how much better it is to use a jump starter when you are dealing with a dead battery than booster cables. In the last few weeks, as we have encountered extreme weather here in Kansas City, this advantage has really proven itself true and reinforced just how handy a quality jump starter can be. We manufacture some really nice jumper cable sets and we know that they are the preference for some users and in certain specific applications, but when you stack up the positives of each approach, it’s really no contest. So, in light of just how awful the weather is right now, we thought we’d revisit the ways a jump starter is the superior choice, especially in extreme cold and snow. In This Weather, Independence is Even More Important No matter the weather, the top advantage of a jump starter is that you are fully self-sufficient when you have one, so when trouble strikes, you are not at the mercy of finding someone to help you out and let you use their vehicle as the host vehicle for a jump start. With your handy Booster PAC or Jump-N-Carry jump starter,

The Value of Voltage Drop Testing

Another great case study by Bob in Massachusetts, this time related to a 2011 F-250 no crank situation that had already had its battery and starter motor replaced before it got to him. As he described it, “At key on, the dashboard lights up but when turning the key to crank, there is a faint click and then everything goes dark.” After checking the battery, which tested good, he headed off on his diagnostic adventure. He immediately started voltage drop testing various aspects of the starting/charging system, in search of the root cause of the issue. It didn’t take long before he started zeroing in on the issue. By his second test, he was able to determine that voltage at the starter during an attempted crank “saw a drop to almost zero volts.” It was then just a matter of time, and a few more tests, before he identified the source of the problem. This case study is very clearly presented, well documented and follows the diagnostic path from start to finish. As one commentator noted, “Your case studies are always so well written and easy to understand. You are a fantastic teacher!” We couldn’t agree more. This is a
