  1. Controllers
    Hey guys, I have a curtis 1236 controller and i want to use the in internal precharge. I have my main contactor connected to the ksi coil return pin (pin13) and the driver 1 pin (pin6). The main contactor is between B+ and battery positive. MY pack is 48V. It seems as if the two pins im...

    When I registered here, I set myself the goal to start my first conversion build in 2018. And a couple of months ago I decided to go for it after I saw the first results of €1000 DC conversion here. To do a build on a shoestring and in a short period of time, the electronics have to be simple...

    Finished Soldering 6 Power Controller boards last night. :) In my Solectria E10, I am planning on having 4 parallel groups of 20 Leaf modules in series (150V @ 65Ah per group), and thus I need a way to pre-charge, connect, and disconnect them to/from the main vehicle power bus. That is the...

    My little Wheego frustrated me a bit by dying in the middle of the road yesterday. I was driving about 30 MPH when it lost power & coasted to a stop, not to restart. The initial error displayed 18 overvoltage, while decelerating it went to error 12 controller over current, then showed 14 when it...

During driving I heard a blow noise (it could be the noise of the contactor went off) and I lost power. No supply, everything gone.. I pulled off the road whilst the...

    I was wondering, because I've had a hard time finding info, if the aux 12V battery is really necessary? Would an EV work with just the DC/DC converter alone, or does that cause issues with the contactor/precharge business? Also, it seems the precharge resistor is something I overlooked in my...

    While my wife was driving my 92 Escort conversion it "died". It started normally drove for about 1/2 mile and the dash indicator that the car is ready to drive went out. See evalbum.com/1818. I pulled the codes from the hairball using the palm pilot to find: *1131 - Shorted / Loaded...
  8. Technical Discussion
    I am starting this thread so I will stop hijacking other peoples conversations in order to sell my step-start delay:rolleyes:. There are a lot of opinions on how to apply power to the controller. There are safety considerations for both the equipment and people. If we can work out some...
