Rando, blowing out a generator is part of the trouble shooting process and yes sometimes it will make things worse but more times than not it will eliminate grounds. But first back to the basics. What do the Generator and hoist motor Meg out to? You must remove brushes and motor leads and Meg everything to see if you are getting any grounds. Then you can hook your field coils to 110VAC and see if you have a even voltage drop across each one. Once you know you have an ungrounded and equal system you can start setting up your compounding and speeds. Also load weighing is huge on these cars as far as adjusting is conceared. So if people have been doing 5 year full load testing without jacking up the platform bolts I can assure you you will have problem there. Get a megger and some weights and start from scratch. You can never adjust an elevator that has grounds that may be changing by thousands of OHMS due to changing condishions like temputure and moisture. Good Luck!!!
