I had an RV style generator on my 18 wheeler that died twice in 3 years, requiring replacement of the voltage regulator. The third time it quite I was in Abilene and went to C I Electric where they discovered the regulator had been wired wrong by the factory and this is what was killing the regulators. C I Electric replaced the regulator and corrected the wiring problem and the unit has functioned flawlessly for four years now. These guys are the best. Nothing flashy, just good old boys doing quality work....! Danny Sunshine Transportation Inc.
