  1. Ground at the source only, generator ! Grounding at a distro point can defeat the main breaker on generator. For verification, put one end of your volt meter on a hot leg and the other to the ground rod, It will show line voltage if it is right. Also, a good ground will show less than 200 ohms to anouther "known Ground" at 6 feet .
  2. Regenerators in Dallas Texas sometimes has used generators and distro equipment www.regenerators.com
  3. Colleen, I wanted to answer you question a little further: Lets say you have a 3 phase generator{120-208volt} For this example we will use LitePower's configuration with a Basler or Marathon voltage regulator. As the engine spins the generator around, it passes each "leg" The leg's are spaced equally in a circle, as it passes the leg that is loaded heavy, the engine has to work hard to produce enough power to satisfy the demand{engine slows down a little}, then it passes a leg that is loaded light it doesn't have to work as much so it passes quickly. This will cause engine speed to vary wildly{Hz or Frequency}. Also , most of our 60,120,and 140kw generators use 2 legs to control voltage. The voltage regulators function is to maintain a constant voltage between phase 1 and phase 2 to our pre-set point of 208 volts. As the leg loaded heavy goes by, the regulator looks at it and says"increase" but when it see's the leg loaded light it say's "decrease". Phase 1 could be as much as 20 volts too high, and phase 2 could be 20 volts low, however measured between them you still get 208 volts, measure line to neutral and it wont be 120 volts. This is a bad thing,however some generators use a three phase voltage regulator{this is the case with our 220KW Generators} with a PMG generator{Perm. magnet generator}. This type of generator is much more forgiving in regard to balancing as each leg is adjusted separately. Also, use the ballast, not the generator's circuit breaker, and ground properly, especially when using dimmer racks.
  4. Good advice Kyle, Balance is actually 20% of Total load used, if you have 100 amps on L1 then L2 and L3 need to be 80 to 120 amps each. Ground it correctly.
  5. Replace the battery and any connections that have any corrosion at all, especially the battery negative. Fresh Fuel ! Disconnect the fuel pump actuator so engine WONT start. Change the oil, and fuel filters. Fill fuel filter half way with dexron mercon transmission fluid. Run through several crank cycles to pump up oil through engine and turbo charger and to get dexron into injection pump, this will clean it out. Now re-connect actuator and crank it up. It will smoke for about 3 minuets or so and then shuld start to run cleaner. It is also a good idea to inspect inside generator for dirt dobber nests and mice. Look at all rotating parts you can see, especially the fan{inside generator}. You may also have to prime the fuel pump, Cummins engines have a bleed port for this, others you may need to crack an injector line to get all air and contaminated diesel out. Woodward and goveners of america sell sync kits but be carefull, if you havent done this before you can easily destroy the engine. I am in Dallas but I can recomend a guy in Van Nuys who can install these units. Hope it goes well !
  6. I see several posts here regarding portable diesel generators for motion picture use. If you have questions you would like to ask a manufacturer of some of these,let's have it.
  7. Guy, Thanks for the detailed response,over the top! In short if you want to be a professional, use professional equipment, not a toy from home depot.
