- Well something broke. Can we fix it? This one gets a bit technical but it's all part of the adventure that is our project. Converting a 40 year old Porsche 928 into an EV. Madness.
If you are enjoying our journey and are as keen as I am to see the EV Porsche on the road, then why not SUBSCRIBE so you can see episodes as they appear. Thanks for watching. Or just a LIKE or COMMENT if you have something constructive to add.

The patience of a saint! I like the blend of MG and Porsche in the dash - I think you're going the correct way about it, by integrating the MG electronics and controls into the 928 interior.
Everything looks great Stu. Good luck with the electronics. 😊
I think you'll want to seal up the shifter hole in the tunnel, as it can be a source of road exhaust (though probably most of that is coming from the 928's engine rather than other traffic). Every episode of this series is great and gives me confidence in taking chances in my own projects
Yes absolutely. Many holes need filling to reinstate cabin integrity.
l really like and appreciate how you are sharing your diagnostic dramas . Might be a bit boring for some but really interesting and helpful for the rest of us ev nerds. More helpful than you realise . As to those questioning your choice of MG, l think it gets more valid as you go along. lntegrating all the other MG components is a great idea and its the cheaper way in for a first timer. Maybe the next 928 conversion might be Tesla based but considering what you have learned with this one l think the experience is priceless . Also it is proving what a wonderful choice the MG running gear will be for many other cars . Many others will benefit from your efforts for sure.
dash looks great. good luck with the electrics !
EV8 already exists as a DIY conversion. It was formerly an RX8. He's been building it for a few years.
I admire your persistance, & still don’t get why you’d bother with this project, but it makes very enjoyable viewing😁
The fun is in the journey. Who knows. When I finally get it going I might go 'well that's disappointing'. Or not. Time will tell.
Stu you are a Legend !!!! A little mad but we love you.
You're crazier. But thanks
Great to see another episode, Stu. How visible are those custom warning lights behind the steering wheel/indicator stalks? They look pretty obscured to me.
You're right. I wanted them inconspicuous but they might be too much so. Hopefully they'll be adequate for compliance.
PORSSSH!? Come on Stuey. LOL
FYI - there is a custom relay that plugs into the wiper relay slot that allows you to set the wiper timer interval by just pulling/holding the wiper stalk. It is a VW part if i recall correctly. In case you were planning on eliminating the original potentiometer switch located under the original pod.
.
mea culpa.
Thanks for the tip. Yes, wiper pot unserviceable so that sounds like a good idea
You know: You two should maybe consider going into the MG repair market.. at this rate you will be Master Technicians on them.
G'day from Norfolk UK. I have been a keen follower of this 928 project and certainly look forward to each episode. Your test equipment and the wiring diagrams are 2 items without which you could not work. Were you able to source the wiring and technical data from the manufacturer? The dash layout you have achieved is excellent. Regards, Roy.
Yeah without those manuals I would have no chance. Originally shared by the EV conversion guys here and overseas who've spent time reverse-engineering the MG ZS EV. Funnily enough, just made contact with a very helpful guy at MG Australia who provided more PDFs for me. Stuff that would have saved me a lot of time early on. He's helping fix our HV contactor issue. Fingers crossed.
I have MG ZS EV (2021) and those phantom HV battery shutdowns can occasionally happen like, for example, if you turn off the car then immediately, for any reason, try to turn it on again and it can be a bugger to get it to clear the error symbol. Something that, for me, seems to fix that problem is to press on the brake pedal extra firmly. Anyway certainly enjoying your series and have subbed.
If you had a billy cart as a kid I imagine it was part UFO 🤯
My dad made a nice billycart for my brothers and for me. It had a proper steering wheel and with a rope pulley system. About 20 turns lock to lock which wasn't a great idea. Drove like a Chevy Impala. And the brakes didn't work. Seemed like a good idea at the time. But wasn't.
Porsche are continuing to sell the older ICE Macan model in parallel with the new EV Macan (in some markets but not Australia) and you can be sure that if the EV does not sell they quickly develop a new ICE Macan model. Porsche is taking a very cautious considered approach to EV.
Check if the brake switch is a switch or a potentiometer.
It has both. The pot only used for determining regen amount and stability control functions whilst driving I believe. Currently set at rest position to prevent "out of range" DTC code. Switch used for other functions like brake lights, start up and shutdown processes, P park enable. And yes, probably part of HV enable process.
@@inCARnationAustralia cool. I was looking at the circuit diagrams the other day and saw mention of a brake pot.
Hey Stu, sorry to see that you’ve had issues, but good on you for going back to basics with troubleshooting skills.
I like the simple solution for the speedo.
I still think that the ideal place for the charging socket is behind the number plate. Plenty of room, easy to get at and invisible.
Re the handbrake, did you see if the rear calipers on your model S could work in place of the MG handbrake? Older model S have a separate handbrake caliper that may do the trick.
@@markedwards4879 Excellent suggestions. I haven't yet tried the Tesla Calipers but I will look. Thank you
I also forgot to mention that the rear brake callipers are pretty simple. Two wires. Connected to 12v one way tightens, reverse polarity loosens. And I assume they use current detection to know when they are fully engaged/retracted.
