Have you checked or reset neutral yourself? I’ve found it off so many times coming back from the motor shop that now I just check it as a rule.

I'll get back to you guys. Today we changed taps on the series field and the best result was slow up no down, even with 55 amp loop current! Very strange. Will try moving the ring. We haven't checked neutral yet though.

Do you have a diagram for the field connections for that generator yet? There may be more wired wrong from the motor shop. A shunt field, series field or innerpole wired backwards. Reminds me of a nightmare with a giant Otis gen we had come back from the motor shop all kinds of F’d up. At least you have other cars to compare. This was a 14 stop freestanding tower to nowhere but that’s another story.

So now, as soon as the generator is powered up it almost stalls like its loaded up and a lot of current through the loop circuit even with GSEF disconnected.

Your GSEF is backwards to the Series field. reverse the leads, then use the leveling field leads to make sure car runs right direction. If wrong reverse them. You cannot disconnect the series field to stop build up. It is wound in the pole piece.

Do everything on inspection and use Uor D and H for leveling field.

Thanks Rolly, I will check that.

Even with GSEF and GLF disconnected the generator is outputting 27v and almost stalling, brush holders get hot. I cant see how it can generate with no fields. Any ideas on this?

You cannot disconnect the series field from the GSEF. It is wound in the pole piece so the self excited field can build. If you listen and do what I told you can get all the fields in sync, The suicide circuit using the SUD relay could have an open resistor. Also on some controllers a breaking contact on H is used in suicide circuit, Does you generaror have taps on the pole pieces, or an extra series field wire coming out to controller. There is no 65 Generator, some dumb ass in the UK stamped it wrong. I had 4 controllers in the Bahamas from UK and I had never seen so many factory wiring mistakes. First time power was applied transformers smoked for touch buttons. Awful Quality. You will notice there is no way for the GSEF to get any external power to the field, it is done with induction via the leveling field to get the build up started. Also all the speed steps pull in all at once,

Was this issue ever resolved?
