Inside the Controller

peter

I finally got some spare time and opened up the controller to see what I could see.
I have a clearer understanding of what most of the lines do – but still do not know where to hook up the accelerator pedal lines. There are 6 lines called “Function” that lead to KB5, KB6, KB7, KB8 and two unmarked inputs on the controller. Not much help there.
I also have a rough idea about the serial lines – three lines that are labeled “gorge line transmit, receive and place” which are hooked to T2OUT, R2IN and one unlabeled wire.

Delays in research

Sorry about the delays – had a week-long face-to-face meeting, compleate with a BBQ at my house and a dinner at a local restaurant. Busy busy busy. I really hope to have time this weekend for reviewing the motor.

Kick Gas Club

After helping set up a plant sale at Balboa Park, my wife and I made a stop at the Kick Gas Club.  Neat little shop set up by a retired mechanic that specializes in helping people convert their car to electric drive.  The purpose was to see if they could help me with the motor adaptor (which they can’t right now), but they did give me some good ideas on how to proceed.

(BTW – if you are going to get a brand new motor – see if someone else has used it first and get their feedback before putting money into it).

Charger isolation

Over the weekend I added some isolation to the charger and removed the ground connections, so the charger is completely floating now (relative to ground). This was done by putting some ABS plastic under the charger, and trimming off the ground wires that attach to the charger.

I also replaced the BMS master board, as the feedback from the charger might have damaged it. Not sure what did damage the BMS, but it is working now.  I also had to turn the voltage down on the charger a bit – I suspect the voltage adjust knob is moving on its own.
