I've completed the main mechanical work on the Citroen and will finally start wiring this weekend. Should have her on the road for testing real soon now. Except that the well pump at the cottage (where my garage is) died a few days ago and the well guy can't get it out. So no water except what I can carry in the Insight or carry in a bucket from the neighbors. Sigh, if it's not one thing it's another. Oh well... Further to my previous questions about the secondary motor, I've obtained a real motor, a 1.6 hp Leeson, to replace the cheap treadmill motor that I've been using. So with a bit of redesign of the mounting bracket I should be just fine. I had a chance in the summer to test drive an S-10 with the Kostov 11" and Zapi sem 3 system at Randy's place, along with a similar pickup with a 9" ADC series motor (I think that the controller was a 600 amp DCP). I did not push either to the limit off the line but both were adequate and had about the same feel. The Kostov sepex had considerably better mid-range acceleration (i.e., from 30-45 mph). Randy has the field coils rewound locally with better insulated (? larger?) wire, because he had some early problems with burnt out field coils in the stock Kostovs. Mike Hoskinson >This is definitely a problem specific to your particular system then, >because I achieved significantly higher regen currents during my test >drive of the CEV MightE truck with the Zapi 96V 500A SepEx drive...
