Well I've traced what I think is a fault on my genny to an open circuit 3 phase transformer. It's delta wired with quite thin primary and thicker secondary. All 3 primary windings show open circuit with my multimeter. I've spend most of the afternoon whistling Old MacDonald's Farm to myself as I stripped out the laminations removing E's and I's interspersed with frequent oh's. I now have a pile of said E's and I's and some wire on order to try rewinding the coils. Fortunately the primary=92s are on the outside. Inevitably, 3 or 4 E=92s broke during dismantling. I=92m working on the basis that 3 out of 120 aren=92t significant and I will probably have trouble getting them all back in anyway. The transformer=92s on the excitation circuit BTW. Is there anything I should be aware of or should I give up now? Would a rewind company do a much better job on a purpose made machine? If so, is it worth just paying them to do it for me?
Thanks in advance
