    Help me with the math for a U-Haul trailer

    Check to make sure the trailer has brakes for loads over 1650# (Tesla Owners Manual) over 1500# (CA law - check your state) MY 2022 isn’t currently working with trailer brakes. No power to the 7 pin.

    2202 MYP tow connector DOA?

    Hi, the brakes and blinkers are working on my March 22 MY. Rocklin service says corp told them it’ll be a two part fix- new set and wiring (harness? module?) I’d encourage taking it in and adding your vehicle to the Aux 12v fix list. The other stuff should be simple. Good luck!

    Charging time Tesla charger vs Standard 50amp outlet

    Good points. The MCU and cable was rested on a plastic storage container. I moved everything away to allow for better air flow. It was 100+ in the garage for over ten days.

    Charging time Tesla charger vs Standard 50amp outlet

    Thanks. RockyH if it’s showing up in a few threads do you think it was a stealth sw change implemented due to so many heat waves in the 100+ range for days/weeks?

    Trailer electrical connector DOA on New MYP

    Thanks for sharing. I agree with you. The last software release included games, yippee. I get the privilege of playing video games, polluting the environment and forking out $150 to fill a truck gas tank. (Ok, I’m being snarky, I’ll stop) The trailer brakes are a safety issue too. You’d think...

    Charging time Tesla charger vs Standard 50amp outlet

    Yep and 98+ % of the time at 32, sometimes it throttles to 16A. I asked them to run diagnostics on the three PCUs, no problem found. Ideas?

    Charging time Tesla charger vs Standard 50amp outlet

    It was charging fine at 32A 98% of the time. It’s cooled 20+ degrees, so will be difficult to reproduce. For now, I’m scheduling charging at 3 or 4am at 24A. I have to decide if there’s any value in installing the wall charger. I want to keep an outlet for the teardrop. They can change the 50A...

    Charging time Tesla charger vs Standard 50amp outlet

    Yep, the outlet is capable, up to code, verified by a Tesla preferred installer who didn’t do the original work. I scheduled this after a service visit & the car suggested it was the outlet should be checked. Electrician pointed to the MCU as the likely problem due to 3OA rating. Also...

    Charging time Tesla charger vs Standard 50amp outlet

    Interesting. The electrician said to throttle to 24A because of the 30A rating. It has been hot here, long stretches with garage temp over 100. I didn’t even try charging until 4am when CA had the heatwave over 110.

    Trailer electrical connector DOA on New MYP

    Third year engineering co-op student found a part online. Not rocket science. But does have to be integrated and supported. It wasn’t generally known. I suspect the impact that trailer brake controllers won’t work wasn’t well understood when the decision was made. I also suspect they mistakenly...

    2202 MYP tow connector DOA?

    12v system doesn’t send power to 7 pin needed for trailer brakes. Tesla service Rocklin is working with corporate on this. The latest update I got was there’ll be a wiring harness retrofit and software. There are a few of us waiting for the fix. I’ve cancelled trips, borrowed trucks, pumped...

    Charging time Tesla charger vs Standard 50amp outlet

    Rocky, this is great info. I have a 22 MY LR. I’ve been troubleshooting a charging issue with over temp. I had an electrician come out and was about to install a Tesla wall charger. The electrician said the 50A outlet is fine. But pointed out the Tesla mobile charging unit shows max 30A. The...

    Blue Model Y waiting room

    I just ran into this with my MY, LR, tow package, March delivery. My brake controller needs the Aux 12v. Trying to get answers from service. The brake controller mfg said all their brake controllers need the Aux 12v.

    2202 MYP tow connector DOA?

    I have a March 2022 MY, LR, with the factory tow package The Auxillary 12v pin on the 7 pin connector has no signal. My brake lights and turn signals work. But, the brake controller isn’t powered. I have the Prodigy RF controller. The manufacturer says all their brake controllers need the 12v...

    Model Y Hitch Receiver: Rise Limit Question

    I think I’ve just gotten stuck on this 3/4” rise limit. I have a NuCamp Tab 320 S Boondock. I’d asked the SA to clarify the requirements when I purchased the MY LR 19” wheels with towing and FSD. He came back saying the tow height is set by the trailer mfg. I took delivery last week. There...
