This post applies to most J1772 handles but specifically the LEAF with the YAZAKI 73A-2002 or 73FA-1501 handle
We received the charger the latch lever on the J1772 handle was loose and floppy. We check the proximity switch between pins 5 and ground and found a constant 480 ohms (switch open). The vehicle will not charge if the switch is open. Browse this link for details. http://bit.ly/J1772HandleTest
The Yazaki J1772 Handle case is particularly difficult because it is held shut by internal pins vs. screws. We used a 1" chisel and a 2lb hammer to gently open the handle. You need to avoid the small pins next to the chisel. there are a total of 9 pins to avoid plus a little clip that retains the spring on the latch lever.
This model of the Yazaki has a plastic pivot pin on the latch handle. (the model 73FA-1501 has steel pins). We epoxied the pins back on and because this plastic is hard to glue we drill out the center and inserted a steel pin. See the finished latch lever.
We thought we were done until we found that the attachment for micro switch was broken. This would probable be Ok because the switch is constrained in the handle but just to be sure we hot glued it under over and behind.
We cleaned up the edge of the handle that had been damaged during opening and using a vise and hammer we convinced the handle to snap together (and it was tight), We tested the LEAF charger on our EVDOC Lab simulator and it charges at 12A without error. We did a 240V upgrade and now with an EVDOUBLER it charges in 1/2 the time!
The SD Auto Show was held Jan 1-5, 2020 at the San Diego Convention Center
I took the opportunity to take public transportation from Carlsbad to the Convention Center. Very easy. Arrived in less than 45 minutes. Cost round trip $7.50 (for seniors)
We were looking for details on the 2020 models especially the OEM Level 1 chargers. How many have a built-in Level 2 charger ie are they 120/240V ready? We did not find a single level 1 charger (guess that is not something to showcase)
Many of the Electric Vehicles were highlighted an area called the 'Ener-G Station'. See the posters listing the current rebates for EV and PHEV vehicles.
The Highlight of the show was the Ford Mustang Mache.
