Check Your Battery Terminals

[KingKona]

I had to do a bit of cleaning and coating. Probably time for a new battery soon. I used CRC Cleaner With Acid Indicator (and it indicated), and their Terminal Protector. All nice and tidy now. I'd hate for corrosion to get to the cables.

No after pictures?! Unacceptable, lol. I like seeing clean/polished

Seriously though, I’m gonna check mine tonight. Mine is garage kept and stored in the winter so doubtful but doesn’t hurt to peak

Yeah, I should have done that. But I'm not taking that craptacular cover with it's magically disappearing push-pins off again to take an after picture.

Sorry, I should have done that before I buttoned everything up. It's cleaned with a heavy red oily protective coating now.

Good that you caught it early. You shouldn’t have any more problems, especially with the heavy oil

Like you said, good that it didn’t get to the cables. That happened to my daily driven 2001 Escape. Had to replace all that crap.

Exactly......

I saw something on some car show about that corrosion getting into the cables, and it just slowly crawls up them and eats them. Then ya gotta replace them.

good one. writing it down on my to-do list

It's definitely worth checking , as evident by some of the cable photos witnessed in threads prior.

I keep a log book of such information. It helps confirm when last checked.

While under hood, check the radiator cap. Some have caught theirs sticking in times past. Once a year or so, I remove mine and use a Q-tip to apply a light coat of silicone spray to the attaching surfaces.

Back to terminals and associated cables...

Just get some terminal/cable protectant and apply it. Then, no worries.

I meant to do that back when I bought the car years ago, but never did.

This is an issue I had posted about a while back.

Ford released SSM 48123 about battery terminal or battery cable corrosion, because at that time it affected model years up to 2019 (not sure if there is a new SSM to cover later years yet). See the actual SSM PDF in the below link:

and yes, if it is bad, the corrosion does wick up into the cable strands under the conduit/insulation. It will continue to corrode just as salt water infiltration would do to wiring harnesses exposed to salt water flooding.

I have never seen such bad corrosion like what happens to the S550's. My theory to this problem is that it is happening due to having a battery box cover with inadequate ventilation. It could also be exasperated by dissimilar metals of battery posts, cable connectors, and inferior wire stranding.

My 94 Cobra has not had any such battery terminal corrosion in my 19 years of ownership and that battery compartment design does not have a closed box. Prior Mustangs, other Fords, and even a few BMW's (where battery is under rear seat or trunk), never had this issue either...

Everyone who has an S550 should definitely check the battery cables if you never have or if it's been a while.

I'd think the fact that the car basically never shuts off, never stops moving electrons around, plays a part too.

Just my guess.

Another good theory too - with all the modern day “tapped in” BS modules and whoosywhatzits.

You need to replace that battery very soon. Cleaning it helps temporarily, I've been down that road on my S550 before.

Second time, battery sat too long and just started failing. On these cars, it's better to replace them.

My car/battery isn't having any issues. Plus, I'm the guy here that tells everyone, no matter what is actually wrong with their car, the problem is their battery.

Flat tire? Battery.
No A/C? Battery.
Seat uncomfortable? Battery.

Noco do a protector too :

There’s some strange things that stay hot on these cars. I recently read about the throttle body, and I suspect something behind the dash on the drivers side, along with something behind the screen on the lane sensing cars ?
