I am working on a 1995 Stewart Stevenson M1078 A. I am having an issue with the charging system. CB77 is good as is K11 relay. However after about 30 seconds my volts gage drops to 0. I pull either CB77 or K11 and reinstall it, the volts go up to about 27-28 for about 15 seconds, and then drop off to zero again. I have cleaned the terminals on the LBCD, Battery cables are good, and the excitor is still having issues. The red light comes on the voltage regulator, and that is when the volts drop off. Can anyone give me some insight as to where the problem may be? I have tried to by pas the LBCD and unit will not even power up when I hit the green button on the dashboard. This tells me that the LBCD is doing its job. I tried going from battery to excitor. That does not work and it powers up the CTIS directly. I am trying to get this going for a fire department to use so any suggestions would be appreciated.
