I finally found out why that 2018 F-150 kept eating alternators
Honestly, I've been chasing a weird electrical draw on a 2018 F-150 for like three weeks at my shop in Austin. Kept swapping alternators and they'd fail within a month. I finally looked up a TSB from Ford's service site and found out a bad ground strap behind the passenger headlight causes voltage spikes. That tiny strap was corroded and barely hanging on. Has anyone else dealt with that specific ground issue on these trucks?

Man, I don't know, that seems like a lot of work for a little ground strap. I mean sure, corrosion happens, but are we really gonna blame a whole alternator eating spree on a tiny piece of metal behind a headlight? Feels like Ford would have seen that and fixed it by now if it was that big of a deal. I've seen plenty of those trucks running fine with a little rust here and there. Just saying, maybe you got a batch of bad alternators or something else is going on.
