Hyundai SantaFe - Surging Lights? New Alternator & New Battery

Рет қаралды 156,056

Ай бұрын

In this video I have a look at a customer's 2008 Hyundai SantaFe that has an issue with a battery draw and the customer states the dash lights and headlights surge when the blower motor is on. This vehicle was already at another shop, and they replaced the alternator and battery. Let this video be a good reminder to not forget the basic checks.

@smijas Ай бұрын

As a light defense,.... The old battery might actually have gone bad .... because the alternator could not charge it sufficient. Eric did a good job explaining voltage drop! I was secretly expecting a rotten (green puss) flexible engine ground cable and a money-shot. But this one was an acceptable alternative! Good fix.

@tjroelsma Ай бұрын

@@smijas Second defense: the alternator also may have gone bad if this situation had been going on for a while. The surging of the engine points to a (very) heavy intermittent load and that CAN kill an alternator depending on how high the current draw surges. Ground errors in a car can be time consuming to investigate and some garages simply fire up the parts cannon and don't want to spend the time when that doesn't solve the problem.

I measured the resistance of the cooling fan switch at the relay panel inside and found the problem. Since it has a rear battery, I used the same jumper cable trick to see if I was on track. Stepped my way from the cooling fan switch towards the battery to find the firewall ground point for the engine was all rusty. Cleaned up firewall and replaced the ground wires. All fixed.

I like it that you never want to appear to be full of yourself, but don't ever sell yourself short. I follow along with your findings, and start thinking of the next step. But ALWAYS you jump to the most effective test that should come next and it only takes you a split second. Just amazing to watch. And know that this is coming from the guy who was always assigned the tricky jobs where you had to work yourself through step by step. Huge respect for your skills!

@spelunkerd Ай бұрын

The vast majority of alternator replacement videos, most done by professionals, fail to show any voltage drop testing before they swap in a new alternator. It's a glaring weakness in the way flat rate work flow pushes guys into cutting a corner that literally takes a minute. After a while, guys forget how to do it correctly. I get that new alternators are more tricky because they adjust output based on a more complex algorithm, but diagnosis is the fun part of auto repair. Great demo, Eric!

@gailtaylor1636 Ай бұрын

It's even worse than that. 95% of the guys that own a multimeter or a scanner don't really know how to use them. Don't want to "know" as that requires time to learn. They got fishing or hunting to do.

I used to have a 90s Corolla which due to the NUMMI deal came with a GM alternator. Those things always had the decency to fail completely. I went through several of them. Those Delco alternators were absolute junk new, and even worse when remanufactured! I bought a newer Corolla and first on the list was ensuring it had a Denso alternator...

Long time viewer, first time comment. For some reason this is a common problem on both Santa Fe's and Sonatas. The bolts going into painted body parts end up with a crappy connection over time. Especially in the rust belt. Common issue causing many electrical gremlins on Hyundai forums. Preventative recommendation was to shine up the area around connection to body, load up on fluid film, put bolts back and some more film. Appreciate the video Eric.

FOREVER GROUND: (best use: steel-framed trailers) 1) Make frame steel shiny (grinder, etc); 2) solder a brass washer to the shiny frame; 3) drill & tap a hole for your ground screw / bolt through the washer; 4) attach your ground wire-. In 5 or 10 years, if it needs it (unlikely), remove the screw / bolt & shiny up the brass washer with Scotch Brite, sandpaper, whatever. * Yes, you can solder brass to steel with no difficulty (& adequate flux).
