Hi Coulomb: What do you think of using a 555 to generate gate test signals? I've adjusted the resistor values to give a close to 10khz frequency square wave output. The transistor inverts signal so high side and low side get 180 deg switching. This would need help working out what series...

Hi Jray3, or anyone else willing, As a backup plan, in case I cannot get the AUS charger I am working on fixed, I am interested in purchasing a 2nd hand one from the USA. So Far, I've not been able to find any stock in Australia. When I contact 2nd hand sources in USA, Even if I have USA part...

Hi Coulomb / KIEV: Would connecting a transformer with diodes as a test circuit like this drawing, allow to generate signals for the gates to allow testing of the IGBT's, or would this end up as a fireball of High side and Lows side switching on at same time? I figure connecting the test...

Hi Coulomb: The DMM I'm using is a UNI-T CAT III I bought from Altronics rated to 1000V When I said cheap, that refers to price and accuracy of calibration, It's just not a Fluke if you know what I mean. The 0.8 on the DIODE test that I am measuring is when the + of the meter is connected...

JRAY3: Can you PM me the VIN number of your car, or post it here? I need to use a USA VIN number when contacting 2nd hand parts places in USA. I want to see what is available as a backup if I can't get my original charger fixed. All of your previous PMs have disappeard out of my Inbox for some...

I'm using a pretty cheap volt meter that is probably way out of calibration, so that would affect my measurements also. I've soldered four wires to a terminal strip, 2 wires from across the 3x BIG electrolytics caps, and 2 wires going out to the transformers. On the Ohm meter readings (in...

Hi Kiev: You've really made life a lot easier with all the documentation you've done for these chargers. I've got the charger out of the can, on the test bench, and using a power cord with fuse from wall socket to the AC input ring terminal screws on the top pcb. I tested the ACTIVE and...

Hi Kiev: That is the most awsome reverse engineering I've seen. At the moment, I put the faulty charger back in my friends car, so they could still use the DC-DC Converter section to charge the 12v battery, and can use a Chademo quick charger to keep the car up and running. I have access to a...

Hi Kiev: The charger that I am working on is back in the car, at a friends house, so on my next visit there, I can do like you say and solder a "LINE" and "NEUTRAL" wires out to a point I can connect a volt meter to and fire it up. Just to be clear, Your Arrow pointing to "LINE" is sorta...

Hi Kiev: On your schematic of the Doghouse, you show the output of the drawing which will either be from the closed relay, or from the bypass resistors. If the pcb is still fitted in the box and heatsink still intact, so you cannot probe the bottom of the board, is there any points on top of...

I tried desoldering the 100x leads from the main charger PCB to the heatsink, but could not get all the solder out of the vias. I tried multiple sessions, but could not get every lead to wiggle as free, so didn't want to try prying and risk damaging any tracks. Without seperating the heatsink...

I've opened up the under side of the box where the DC-DC Converter is located. This picture is the result. I've checked the Mosfets along the end of the PCB, and I've checked all the fuses onboard. visually there are no places that look like smoke has been let out. I am thinking that any...

Finally got the pictures to come up, Did not realize its literal text while editing the post, and picture does not appear until posted. This is the daughter board that emulates the two blue thru hole caps. I think it originally had 4 caps on the board, with spare pads for other unpopulated...

Hi Kiev: Thanks for your help with posting images, I'm still missing something, as when I cut and past it just puts the litteral text of the link, the picture does not appear on the page. Below is link to a picture of the doghose that I've removed the black potting so the PCB is exposed. In...

I've been able to remove the main AC Charger board out of the box. One earlier comment in this thread from another person stated that all of the solder joints along the two white strips had to be desoldered to get the PCB out of the box. This is not correct. I fist labeled and unplugged all...

I'm adding a discussion that was on a PM to this thread, as it might be helpfull to others: It sounds like you have done quite a bit of research to getting this fixed. The CAN buss probably controls the functioning of the box so that may hinder testing, but the spare pack and 12V is a good...
