Got the PDU wired up and the EVSE kicks on and off and sends 230v to the charger and the PDU clicks but the zombieverter says PP and CP absent and not detected, aux battery is at 9v so going to charge that up and see if that is the reason or if there is another problem going on. I am going to go ...

okay,

this appears to be the PDM connector pin diagram for the 2018+ PDM

so pin 11 is CAN-L and pin 27 is CAN-H

pin 16 is ignition or switched power.

pin 18 is constant fused +12vdc power

pin 29 is proximity

Pin 30 is pilot

I'm assuming we're talking a Gen2 inverter, so no wire between motor and inverter?
I never shielded DC cables but it does cause issues. I had to reroute the CAN cables further away from the power cables.

It may be cheaper to shield the 12V wires instead of shielding the DC wires.

OEM systems ...

One thing that's not usually done but which could help is coupling HV+ and HV- to ground via capacitors near the inverter terminals. I think this should have a considerable effect on reducing interference from the inverter to the BMS, but haven't tried it myself.

Some kind of low capacitance high ...

Hi!
The hull is mahogany, and it has not touched the water yet.
Cables between battery and inverter are unshielded, so that might be an issue to look into.
Im thinking that the interference comes from the actual switching done by the inverter. If this is the case, it should show up as ripple on ...

Okay, now to start on the main harness to PDU and checking to see if the PDU I have is good. Does anyone have the third gen PDU connector(s) and pin diagram by chance? there is a main PDU connector which is like the inverters connector and then another small connector that goes into the PDU, not ...

Hi!

Got my nissan leaf motor and inverter installed in the boat. All works fine except that Im getting electric interference on the boats 12V system when the inverter is running/switching. I first noticed that the Oled display to the ennoid BMS started to "drop pixels" when I put the motor in fwd ...

The EXT CAN1 is for vehicle communication.
You should connect the inverter along with the ISA shunt to EXT CAN2.


Thank you! That worked and motor spins.

Now to start on the PDU. I have to figure out if the one we have is damaged or not. When it was in a crash the PDU case got a big hole in it ...

The EXT CAN1 is for vehicle communication.
You should connect the inverter along with the ISA shunt to EXT CAN2.


Would there be a conflict if the inverter and CAN-H & CAN-L of the inverter and ISA shunts are connected to the CAN EXT 1 of the VCU?

I probably misunderstood the video then ...

I want to see if anyone had any-thoughts on my gen3 set up, maybe i am missing something, but no can communication from the inverter and cant get it to power on.

here is full detail of what I have done so far.
viewtopic.php?p=39897#p39897

just going over everything and double checking everything.

I can not get the inverter to come on.

I made sure that there was a good ground for the 12v system and I am using a fused battery input that powers a power distribution block that feeds the VCU +12vdc and the VCU goes to the common ground ...

T15 on
Run mode
Throttle is responding and Tq command being sent.
No Errors

For some reason no can communication with the inverter.

With a DMM: positive lead to blue CAN Wire and negative lead to the green CAN Wire. I measure 156.1mV to 158 mV.

Blue harness can wire goes to blue wire CAN EXT 1 on the zombieverter. And the green wire goes to CAN EXT1 low.
Since no PDU is connected yet I put both blue can wires together and both ...

Got everything wired up on the bench and everything seems to work, but have no invudc.

I have switched power going to pin 18 of the inverter or the red wire of the main harness and constant battery power to pins 1 and 6 or the pink wire of the main harness.

Now going to check for voltage for can ...

I know at this point it is a bit over kill, but I am just testing and recording as I go along and this is kind of my digital notes so I know I am rambling a lot and for that I apologize I want to be 99.9% sure I know every wire for where they go and what they do before I put power to it so I don't ...

Okay now the image and diagram match. And the drawing is as you look at it on the inverter.

I wanted a more accurate drawing and orientation. I was also curious to how many degrees the connector twisted in got approximate degrees.

I made a correction to the drawing, I forgot to add one pin in the drawing and got the arrows pointing to the correct pins in black ink.

Just to remind everyone again that there will be some missing parts from VCU kits. Some components are just impossible to find at the moment but I am doing everything in my power to obtain genuine parts. I have not changed my prices despite me having to do a LOT more work myself to avoid nonsense ...

Planning wiring up the motor tomorrow and decided to check the polarity. Can anyone verify that this is correct orientation for third gen inverter.

I have positive on the right and negative on the left near the alignment pin as you look at it from Infront of the reducer.

I tested the polarity ...

Found where that grey wire goes. I traced both ends and that wire is grey from the main harness, through the motor harness until you get to just before the PDU connector where it goes into the resolver wires. Just after the resolver connector that single grey wire splits into two grey wire, one will ...

Okay back it today.

I am checking polarity of the black/red stripe wire from the main harness and pink wire which I have isolated and determined that they go to the inverter.

I believe that the black wire with red stripe is the common ground for pins 4 and 10 of the inverter harness connector ...

Okay, I believe I have the correct orientation for the diagram and it matches up to the image Darla posted. And seeing the pins that are paired in the main harness connectors makes it a bit easier to see which pins I need to apply constant power and switched power to.

Can anyone confirm that pin ...

*** I just realized that the inverter drawing is flipped and inverted and I need to redraw it for the correct orientation and this was based off of the image Darla posted and what I found on my connector and harness. I also realized that the way you read the diagram is like how you read Japanese ...

Hi,

I don't know the pinout, it might be worth checking the maintenance manual if you haven't done already.
On another note, we don't use the big main connector, so if you want some I can cut them off and post to you.


I have looked in in Chilton’s, and several other manuals, but didn't find ...

Here are a couple for images that I couldn't fit above
