Success! :D :D Turns out the problem was an assembly error, spot the problem. :roll: I'm seeing the same 6v lower condenser voltage as well. There is a trim circuit in the data sheet but I'm not sure it would be worth the trouble. I would suggest testing this and seeing if any problems...

Previous post looks good. The data sheet is confusing because the pin numbers on the example are for the SIP package, that doesn't seem to be available. You have to use the conversion chart for the DIP pin-outs. Thanks for this info, I have the pins bridged but I am suspecting that I should...

Using the pin assignments from the data sheet. Shouldn't pins 3 and 4 be as follows? pin 3 signal pin 19 pin 4 12v rtn pin 22 and 18

Here's my board refitted looking pretty. To bad it doesn't work! :( I've got different symptoms now. Previously the condenser voltage live data stayed at 0 volts all the time. Now when trying to start I get an over voltage fault and live data shows condenser voltage staying at 420 volts...

I've got my AD202 and PCBs from China! :D Now to check that I got the layout correct. :shock: I'll solder it in tonight and try it on the car tomorrow. Spent last night desoldering the hybrid board. My TS100 at 19 volts wasn't really up to the job, particularly with pin 4, the main circuit...

Figure 1a on the data sheet also shows the chassis ground symbol, I don't think it is relevant for the connections.

My AD202 got to Edinburgh this morning so hopefully I'll see it tomorrow. The simple pcb I designed and ordered from China is in transit, last tracked in Germany so I should get it Monday. I'll have 4 spares I can post, I'll test mine first. I missed out the 2k resistor :shock: but I'm going to...

I've fully tested the ISA215N board on my MCU and it's goosed. Using the ISA215N datasheet and google translate I determined that I am seeing around 4 volts briefly during precharge on pins 1 and 2, as expected. I'm getting 15 volts on pin 5, also as expected, but pin 3 is always showing -0.4...

Here's a graph of the actual condenser voltage when trying to put the car into ready mode. Live data stays at 0 volts even though the condenser is precharging fine. http://imgur.com/gallery/5aN5M3G Edit: fixed broken picture.

Thanks for the link Eddie49. I've had the circuit board out of the MCU and inspected the ISA board. Test wires had been soldered to the 8 pin op amp and according to the thread above and speaking with the previous owner he had been able to get the car to move on a couple of occasions. That tells...

Hello from the Scottish Borders. I've just bought the iOn from page 10 of this thread. I've done a few EV conversions in the past and bought a Leaf in Feb. Now I'm hoping 3rd time lucky as at least 2 people have had a go with this iOn. Symptoms of this car when I got it is that when you tried...
