Not sure if this helps any but I couldn't get a PWM controller to work with the Nissan Leaf pump and ended up using an Arduino to send a 2hz signal and changing the duty cycle controlled the speed of the pump.

Hi Neil
I'm sorry I missed following this thread, I saw it in 2022 and even commented but unlike Landyzone this forum doesn't automatically subsubscribe if you comment which feels a bit odd.
Anyway it was great to meet you recently and having seen your build in the flesh it is as awesome as it looks ...

oh and that Leaf charge receptacle has leads even shorter than the Walmart one

Nah, I was talking about your wee short wire.

The other end goes to the charger in a 2011 Leaf

Looking good mate.

when searching for a charging receptacle I was surprised to find one at Walmart, so I had to order it

I don't think this could have come with a shorter tail

thank you and yes they do, I even own a couple of them and thought about testing one of them in my kitchen sink with that PWM controller off of AMAZON but you may have just saved me the trouble, I wonder if your code and the Arduino gizmo will work on the GS450h/Camry/Altima ones

Say it with me now: That aint going anywhere!

Where I come from they usually say "That ain't goin' nowhere"
I suspect pointing out the double negative may be lost in translation. :lol:


Sidebar, and a call for help

gents ...

I have actually and I'm not there yet I am just barely getting to tack welding without my elbow high Lincoln ppBuffalo Rhino thick welding gloves and in a short sleeve T shirt

honestly there is no way in hell to do some of the tight and tricky upside down sideways welding in all the proper safety ...

Have you ever watched Fitzee's fabrications. He does awesome work on rust repair but rarily wears a welding helmet.

Are you going to replace the floors or just put extra stiff carpet down?

slightly revised schedule for the purpose of steadfast driveability with some built in padding for nice to have little things like: brakes and seats which I will do off camera on this forum anyway, the Flintstone floors will be delt with later... much later

For anyone with an earlier Zombie without the direct solder connections for the wemos ESP8266 or ESP32 this seems to be working for me.

The Olimex plugs into 10 pins marked "ESP WiFi Module" "Conn1"
Connect it as shown here, only the four pins on the RHS are used.

I didn't think that would stand the Greg test!

I'm scared enough being around 400V but the thought of 600V is just NO!
You're a braver man than me.

I've been using the ESP32 in my Zombie for a couple of weeks and so far so good.
I haven't seen any communication errors since installing it and before they were frequent so I'd say this is a very worthwhile upgrade.

Check all your pins in the header are fully pushed home, I had similar issues and it turned out one of the pins hadn't fully clicked in so wasn't connecting. It would be worth double checking your soldering too.
If your precharge is working and the Zombieverter is going into run mode then the Gnd ...

Here are some logs from the charger in my Gen 1 MG5

no sir, not yet, was wondering if JBUGS is a reputable source, or if they are the LMC Truck of VWs ? ha ha I don't care for aftermarket parts and was also looking at maybe landing some used ones, why do you ask ?


Didn't you ask us to remind you?
Maybe you told yourself to remind yourself to ...

Did you order replacements yet?

For anyone trying to upgrade their Zombie WiFi from ESP8266 to ESP32 and unsure how to do here is the numpty's guide for people like me.

First order the ESP32's that Tom linked to. https://s.click.aliexpress.com/e/_c3QjPOaj
If this link fails then search for Wemos D1 Mini ESP32. There are some ...

Yip, I really am a numpty, the phone messing about cost me a couple of hours.

ESP32 installed and working a treat. I was hoping this would stop the communication issues and so far so good.

EDIT: Ignore this, I should know better than to try to use a phone to connect to a local WiFi.
I've used a laptop and it is working as expected so now I will plug it into the Zombie and see if it works.

I've bought a few of the boards linked by Tom and had a go at installing the firmware but ...
