    Roadster chasing a Roadster at Laguna Seca

    905Wh/mile average :-) Figure that is about 40 miles of range when fully changed (70% battery).

    Roadster chasing a Roadster at Laguna Seca

    Refuel EV day at Laguna Seca yesterday... did a 1:57.784 in the time trial beating my personal best (1.5 Roadster with original battery). The Performance Model 3 is quick - nothing else production there could touch them.

    254 is alive... needs firmware

    Opps... it is #254... I will see if a mod can fix.

    254 is alive... needs firmware

    I picked up #254 about a year ago as a project car. History - the car had a disagreement with a tree back in 2009 which took out the headlight and damaged the front-right suspension. Not a scratch on the hood. The car hasn't been touched since. It has done 5800 miles, is still on the factory...

    Powertrain failure alert, working 10 mins later

    The car is very confused about the new TPMS sensors. I ordered them pre-programmed and figured the car would learn after 20-odd miles. They came up almost immediately - FL 30psi, FR 30 psi, RL 40psi, RR no information. Drive for 21 miles, stopped, restarted car - FL 40psi, FR 30psi, RL 40psi...

    Powertrain failure alert, working 10 mins later

    No dash removal, just the ESS. It is a 1.5 so I don't think there is a 12V battery. Not getting any 12V errors.

    Powertrain failure alert, working 10 mins later

    Good news first - I have been driving the car for the last two weeks! Bit of a change after driving a Leaf for 6 months! Two minor problems remain... the airbag warning light is on and it is report TPMS Hardware Error. I ordered a set of replacement TMPS sensors in case that is the TPMS...

    Powertrain failure alert, working 10 mins later

    The car completed charging and the error has gone away... car turns on with no fault codes! Next up is reassembling the rear suspension and clearing a path to get the car out :-)

    Powertrain failure alert, working 10 mins later

    Car booted back up. It is throwing an error "Backup power service required" but the battery is charging. I will let it finish charging then investigate the backup power path.

    Powertrain failure alert, working 10 mins later

    New relay installed and the ESS is back in one piece. Now just have to put the car back together.

    Powertrain failure alert, working 10 mins later

    Broke one of the studs off the new relay (well not strictly new). Another new relay on order :-(

    Powertrain failure alert, working 10 mins later

    I got the relay out. The area around both studs is equally crispy. No damage to the relay housing. Thinking either A - poor contact to one of the studs resulting in heat which coupled through the relay path to the other stud, or B - poor crimp of the main power cable resulting in heat coupling...

    Powertrain failure alert, working 10 mins later

    Nuts didn't seem loose, though without the nylon they unwound easily once started. Both nuts and surrounding areas looked to have the same damage (ie not obviously one side causing the problem). The different metal bars and rings connecting to the studs all look tarnished from heat. The small...

    Progress... I installed a 2-post lift last month and spent the last week slowing working through the procedure to remove the ESS. Got the cover off the ESS today. It looks like the contactor ran a little hot... the nylon in both nylock nuts melted and dripped down.
