I'm assuming here that you're using a series DC motor because I don't recall that GE made any EV1 controllers for separately-excited motors. I may be wrong about that, however. But if your motor is series-field DC, and the GE EV1 is indeed not among the living, and time is more important than the budget, the quick fix would be to replace the EV1 with a modern controller. I guess you could say that Curtis is a more or less "standard" choice here. They've been making road EV controllers for for many years. Their former incarnation, PMC, built the DCC-96 bipolar transistor controller used in the Bradley GT EVs in the late 1970s. Something like a Curtis 1238E-6521 (rated for 48-80v systems) should be plenty to get your car rolling, assuming you have a 60v battery, which your message suggested. There are other reputable brands, such as Zilla and Alltrax, but 60v seems to be kind of in a "no man's land" these days. Kelley controllers are cheap, but I've seen mixed reviews of them. Maybe others here will have further controller suggestions. Please let us know how it goes. We're pulling for you and your uncle!

Re: [EVDL] 85 Year Old Uncle Worked 30+ Years on EV, Needs Help Update #1
Update #1 Corrected links to pictures that were conditioned for insertion into another server, they should be visible now. New comments appended. I am trying to help my 85 year old uncle realize one of his bucket list items while there is still time, to drive this car at least once. He has been working for over 30 years to slowly build an electric car using the GE EV1-B controller that he purchased in 1984. The car chassis was hand built: http://ptandjb.com/eddiesEV1/carfront0491.JPG http://ptandjb.com/eddiesEV1/carside0490.JPG It was finally finished recently and is in a machine shop in Ludlow Massachusetts. When we attempted to power it for the first time it failed. Overview of controller assembly: http://ptandjb.com/eddiesEV1/EV1fullview0483.JPG http://ptandjb.com/eddiesEV1/EV1closeup0485.JPG I have attempted to study the schematics and all available documentation. In my distant past I have a degree in electrical engineering so I should technically understand all documentation and pretty much understand how things should work. Relevant documents uploaded into my webpage directory: http://ptandjb.com/eddiesEV1 Included is the most legible and complete copy of manual EV1.pdf with wire diagram used on page 17. Re Cor’s comments: The controller may be perfectly fine. If there is no voltage on points L3, L5 and L7 *in reference to traction battery negative* then fuse 3 (15 amps) is blown or a mis-wiring has happened, because only fuse 3 and the key switch are between L3 and battery positive. I made an error in my first post, should have said L4 not L3, corrected below. I did have BV 59 volts at L3. Using the “General Electric EV-! B, C, D Panel Replacement parts Lists and Troubleshooting/Tune-Up Instructions” manual, I noted that with SEAT and BRAKE switches bypassed and KEY, FWD, and ACCEL switches appropriately set per 3rd bullet point in Symptom section 1B there is not BV at L4, L5, and L7, just minimal voltage. It appears but not confirmed that the new never used but 30+ year old EV1-B controller is defective and am at a loss on how to proceed. Any advice would be appreciated.
