spoke with geoff....he doesn't do tech...just parts........getting parts is not my issue......knowing what to get is:.........model number is 4lm38b = dayton generator with a generac stator.rotoe assembly.....guys if you google that model a manual will come up with wiring diagrams and all and you can see what i have serial no is 3098257 ..........so i'm right back where i was.....with a busted azz useless generator no one can seem to fix......question is how and what do i start to test??? i will fix this!!!
Here are some things that could be the issue. Slip rings and brushes need cleaning and checking for correct wear pattern, voltage regulator dropping out after it warms up a little, DPE circuit breaker making and breaking(auto re-set breaker) due to age or overload, stator and/or rotor windings damaged. If you are going to tackle this yourself you need to get a diagnostic manual for the unit or at least a similar machine. Call Ziller and talk to Geoff, tell him as much info as you have about the age, model #, serial #, engine make, RPM, and describe the control panel. It sounds like something from 2004 or older.
